mike welton
chairman the industry context
2012 was a year of difficult macroeconomic conditions and depressed capital markets the
energy industry however has performed strongly and continues to present opportunities for
growth signs of recovery in western economies and world financial markets are at an early
stage but it is encouraging to start 2013 on a stronger note commodity prices have
remained remarkably stable providing a healthy backdrop for continuing investment and
new opportunities although costs are rising in some areas good projects are still earning
attractive rates of return
premier’s performance
premier has again achieved strong growth in the value of the underlying assets of the
business in 2012 we increased production by 43 per cent cash flow by 66 per cent and
report record profitability for a fifth successive year reserves and resources now amount to
773 million barrels of oil equivalent mmboe compared to 513 mmboe at the end of 2011
four new projects also received development approval during the course of the year while
we invested in excess of us250 million in acquisitions and us772 million in development
and exploration projects during the year balance sheet gearing remained stable at 36 per
cent and is well within our target range we continue to have good access to several
sources of debt capital both reducing our average cost of debt and extending its maturity
this strong operational and financial performance supports continuing investment in new
opportunities an increasingly material exploration programme and the initiation of a
dividend payout for the year
premier’s growth plans
building on the new fields which came onstream in indonesia and vietnam in late 2011
2012 saw a significant increase in group production 2012 average production of 577 thousand
barrels of oil equivalent per day kboepd will rise to a run rate of around 75 kboepd as two
new fields huntington and rochelle come onstream looking further ahead we have
made significant steps in progressing the solan and catcher projects which are expected
onstream in 2014 and 2016 respectively these new fields together with our existing
producing areas will underpin our mediumterm production target of 100000 boepd
we continue to invest in new project opportunities where we see the potential for attractive
returns for shareholders we are delighted to have secured the operatorship and a large
equity interest in the sea lion field in the falkland islands our project team is already
working closely with both the falkland islands and the uk governments to deliver an
approved development plan by the middle of 2014 we also look forward to our first
exploration campaign in the falkland islands which further builds up our increasingly
material drilling programme
our 2012 exploration programme delivered successes in the uk pakistan and indonesia
these are valuable additions to the portfolio due to their proximity to existing producing
assets in the uk central north sea our exploration drilling programme attempted to
replicate the successes we had in the catcher area in previous years however with the
exception of the carnaby discovery in a new play area west of the catcher development
the programme was unsuccessful this serves to underline the necessity as we grow our
production and development asset base to identify new basin opportunities for future
exploration away from the more mature areas in the north sea and south east asia our
exploration and new venture teams have done an excellent job in identifying and negotiating
entry into such opportunities offshore kenya in the north falklands basin in the phu khanh
basin in vietnam in the mandal high area in norway and in southern iraq over the course
of 2012 the team added approximately 1 billion barrels of oil equivalent bnboe of
prospective resources to the portfolio we look forward to maturing these for drilling over
the next two to three years success in any of these locations because of the nature of their
playopening potential will be transformational for premier focus of the board
as the group and its scope of operations expand the board has taken a number of initiatives
to ensure longerterm plans can be delivered successfully a comprehensive strategy review
incorporating asset profiles capital allocation and funding plans was completed in the first half
of 2012 and has been reviewed again by the board in the first quarter of 2013
significant progress has been made in the way in which risks are identified analysed and
mitigated throughout our operations reporting back to the board via the audit and risk
committee the board’s nomination committee has with the help of the senior management
team taken new initiatives in succession planning career development and competency
programmes members of the remuneration committee have held a number of meetings with
key shareholders and advisory bodies to ensure that our remuneration policies achieve an
appropriate balance between reward for our investors and incentives for our employees at the
board level we continue to devote significant time to the management of the critical issues of
health safety and the environment the group’s improving record in all of these areas is
testament to this effort however the tragic accident in december in which a crew member on
an emergency standby vessel close to our balmoral facilities lost his life in extreme weather is a
sad reminder of the need for constant vigilance and determination by all industry participants
returns to shareholders
we recognise that the upstream industry is a sector in which substantial capital growth can be
achieved by companies focused on shortterm exploration success such exploration activity
yields potentially attractive but inconsistent returns it is our objective to provide investors with
consistent growth above that of the major companies in our industry but with the potential for
higher returns through our exploration activities
premier’s share price today stands higher than at 1 january 2012 and over a fiveyear period
has significantly outperformed the ftse allshare oil and gas producers index however we
recognise that the share price has not kept pace with the growth in value of the underlying
assets of the business the onus is on the board and the executive team to deliver on our
growth plan and to demonstrate an improved return on our exploration programme so that a
higher market rating will be achieved
the board has also considered again our policy in respect of shareholder distribution as
foreshadowed at the annual general meeting in may 2012 the board intends to propose a
2012 dividend of 5 pence per share to be approved by shareholders at the june 2013 annual
general meeting the level of future payouts will depend on the progression of cash flow over
time and the capital required to fund our investment opportunities but the board believes that
the payment of a sustainable dividend underlines our confidence in rising cash flows the strength
of our balance sheet and the quality of our asset base it is a reward too for the loyalty of our
shareholders we also thank our employees all of whom participate as shareholders through
our employee longterm incentive plans for all of their hard work in 2012 we all look forward to
2013 and the continuing growth in the company as it achieves its mediumterm aspirations

chief executive’s review we focus on growing the underlying value of the business through
disciplined investment in high quality projects our skill set and
experience give us the confidence and capability to take on complex
operated development projects typically offshore and utilising
floating production systems we believe in offering our investors and
our employees continuing growth opportunities reflected in rising
production targets we will judge ourselves and invite others to judge
us by the growth in our net asset value nav per share yearonyear
without relying on a rising oil price we target in excess of 10 per cent
nav growth per share per year and over the sevenyear period to
end2012 have achieved in excess of 15 per cent going forward we
will source this growth from the development of existing assets new
acquisitions and material organic exploration while maintaining a
strong balance sheet so that we are well placed to take advantage of
attractive opportunities as they arise
in the fiveyear period since 2007 we have generated impressive
growth in all key financial and operational metrics which define our
business our growing undeveloped reserves and resource base will
support substantial future growth

our growth rates have significantly exceeded the 54 per cent rise in
the oil price over the same fiveyear period the majority of this
growth has been financed by the reinvestment of internally generated
cash flows or new debt funding with some us11 billion of cash and
undrawn facilities on hand and a gearing ratio stable at 36 per cent
our balance sheet continues to provide a strong platform for further
material growth
reservoir performance from all our producing fields in 2012 was
encouraging and generated a 43 per cent increase in working interest

over the last
five years
q 
were you
pleased with
premier’s 2012
production
performance well productivity was supported by improved facility uptime in the uk
indonesia and pakistan we continue to work on the redevelopment
of the kyle field in the uk which has been shut down since december
2011 following a severe north sea storm the supply of additional gas
to the indonesian domestic market which would have generated
further gas sales remains under discussion with the indonesian
authorities these two factors reduced 2012 production by around
4000 boepd though value will be recovered by a combination of
insurance proceeds and future production equipment issues at our
chim sáo field in vietnam notably with power supply prevented the
full application of water injection limiting our production rates from the
field this is being addressed and overall the field continues to produce
above the level originally anticipated in our field development plan
first oil from the huntington field is expected at the end of march in
line with our 2013 budget after a ramp up period the field is expected
to produce 2530 kboepd gross following a successful development
drilling programme the smaller rochelle field premier share 15 per
cent is now expected onstream around midyear after storm damage
to the initial development well the rig is currently drilling the
rochelle west well and will return to rochelle east after first gas
further significant milestones were achieved within our development
portfolio during the year especially on our operated development
projects the pelikan and naga projects which will sustain and grow
our position in the singapore gas market received development
approvals and will add to existing volumes in the natuna sea from
2014 onwards the dua and solan fields received project sanction
during the course of the year and are progressing well towards first oil
in 2014 on our operated catcher development in the uk north sea
concept selection was formally agreed in december and various
tenders are now under way for key contracts we expect to submit the
field development plan for approval to the uk government once
these tender processes are complete targeted first oil date will be
driven by the contract negotiation process notably for the floating
production storage and offtake vessel fpso elsewhere we increased
our equity interest in the bream area in norway and are working with
the revised partnership group to finalise development plans in
mauritania the partnership submitted a development plan for the
banda gas field though this remains subject to final agreement on
a gas sales contract
in line with our stated strategy we were delighted to acquire
operatorship and a significant equity interest in the sea lion
development project in the falkland islands during the course of the
year with some 350 million barrels of appraised oil in the sea lion
field and nearby discoveries a clear fit with our development skills
and an attractive fiscal regime this is a substantial opportunity for
premier it is also exciting to work in an environment where there is
such strong support from both the falkland islands and the uk
governments the location of the islands raises logistical and
infrastructure challenges however the resourcefulness of our own
project team members and that of the falkland islanders gives us
every confidence that these can be more than adequately addressed
q 
what milestones
did premier
achieve in 2012
with respect to
its development
portfolio
q 
what are the
key opportunities
and challenges
associated with
your entry into
the falkland
islands building on the work that our partner rockhopper exploration plc
rockhopper had already commenced we expect to make key
development concept decisions during the course of 2013 with final
development approval targeted for mid2014 this should facilitate
first oil from the sea lion field during 2017 whilst the geology of the
north falklands basin is complex we also see a large number of
prospects and leads which offer potential for future exploration we
are working closely with the rockhopper team to define the targets
for the next exploration programme now expected in late 2014 or
early 2015
the falkland islands transaction contributed significantly to a 51 per
cent increase in reserves and resources yearonyear while the sea
lion field has been fully appraised our reserve booking policy
dictates that resources associated with the field will not be booked
into the reserves category until further development milestones have
been achieved
as at 31 december 2012 proven and probable 2p reserves on a
working interest basis were 292 mmboe 2011 285 mmboe giving a
reserve replacement ratio of 134 per cent

the percentage of liquids in total reserves and resources has increased
to 67 per cent 2011 51 per cent given that the price we receive for
our indonesian gas volumes exported to singapore is linked to oil
prices around 88 per cent of our resource base is effectively oilprice
driven our current development portfolio is dominated by oilbased
projects
premier’s exploration programme over time has generated notable
successes indeed the largest projects in our portfolio – our gas
reserves in the natuna sea our chim sáo oil field in vietnam our
catcher field in the uk – come from premier exploration drilling
initiatives in 2009 we set a goal of adding 200 mmboe of net 2p
reserves over a fiveyear period based on discoveries to date the
followon potential which they have generated and the programme
still to come we are confident that this objective will be achieved
we added four discoveries to the portfolio during 2012 the carnaby
discovery adds additional reserves on the catcher block and is
encouraging for the ongoing exploitation of the smaller accumulations
around the catcher field itself the catcher area nearfield exploration
has commenced in 2013 with the drilling of the bonneville prospect

with the k30 well on the kadanwari lease and the bbn1 well on the
badhra field these two discoveries added 116 billion cubic feet bcf
gross and have both been brought into production postdiscovery
however we recognise the need to update the portfolio as prospects
are drilled out and as areas like the uk north sea become mature
this is why we have taken steps to add new areas in kenya iraq the
falkland islands deeper water acreage in vietnam and the mandal
high area in norway we believe in targeting playopening
opportunities which on success will deliver not just one discovery but
will open up a series of prospects and leads success in any of these
areas would lead to multiple opportunities and reduced risk over
time such new acreage additions in 2012 were significant with a total
of 30 new licences amounting to net acreage gain of 11800 km

in 2013 premier plans to drill 15 exploration and appraisal wells this
includes five high impact exploration wells targeting in excess of 150
mmboe including the luno ii well which is currently drilling on the
south west margin of the utsira high and the lacewing well premier’ s
first high pressure high temperature well in the north sea in addition
we look forward to the results of the kuda laut and singa laut wells in
indonesia and the ca voi exploration well in vietnam the latter is a
true frontier exploration well with the potential to open up a new play
in eastern vietnam we also hope to replicate our near field exploration
success achieved in 2012 by the drilling of six near field wells in 2013
including the matang well in indonesia and the bonneville well in the
uk north sea both of which are currently drilling
we continuously review the structure of our organisation to get the
most out of our assets and to optimise project delivery during 2012
we reorganised our teams into six country units – uk norway
indonesia vietnam pakistan and the falkland islands – reflecting the
growing critical mass of those units and the need to have strong local
presence in all our key business areas at the same time our exploration
teams now report directly to a central exploration function pulling
together all the technical skills in the group into one team and
allowing us to make better informed choices about where to allocate
our exploration funds we continue to believe that our organisational
model – strong local units supported by a head office team focused
on critical decision points – will deliver our ambitious medium and
longterm goals

premier’s entry into the falkland islands was completed in the fourth
quarter of 2012 our primary focus is to develop the estimated 300 mmboe
sea lion field currently targeted for project sanction mid2014 working
closely with rockhopper we have also defined the lead and prospect
inventory such that a minimum of three exploration wells are now
planned for 20142015
highlights and achievements 
• completed acquisition of 60 per cent of rockhopper’s
licence interests in the falkland islands
• assumed operatorship of the 300 mmboe sea lion project
• lead and prospect inventory defined ahead of a 20142015

premier oil falkland islands
one of our greatest
achievements last year was
our successful entry into the
falkland islands through the
farmin for 60 per cent of
rockhopper’s licence interests
in the north falklands basin
the current focus of the
falkland islands business unit
is the development of the sea
lion field and the exploitation
of the remaining exploration
potential in the basin”

sea lion satellites development 
in july 2012 premier agreed to farmin to 60 per cent of rockhopper’s
licence interests in the falkland islands including the sea lion development
project following the approval of the falkland islands government the deal
was completed in october with an initial cash payment of us231 million
in addition premier will pay an exploration carry of up to us48 million and
subject to field development plan approval a development carry of up to
us722 million these are fullyfunded from a combination of existing cash
resources facilities and cash flow from operations premier and rockhopper
also agreed jointly to pursue exploration opportunities in the falkland
islands and analogous plays in selected areas offshore southern africa
the sea lion field is located on the falklands plateau 220 kilometres north
of the falkland islands and lies in 450 metres of water the geological setting
is a northsouth atlantic failed rift with primarily early cretaceous to tertiary
fill in a typical half graben structure with a large bounding fault in the east
the sea lion accumulation is close to the eastern margin stacked early
cretaceous lacustrine fan reservoirs contain waxy 28 degree api crude oil
oilinplace is estimated to be over 11 billion barrels with 300 million barrels
gross recoverable including the discoveries at casper and casper south
the transaction added approximately 230 million barrels of net contingent
resources
the sea lion field is expected to be developed by drilling and completing
subsea wells in manifold clusters tied back via flexible risers to an anchored
fpso water injection and gas and produced water handling facilities will be
provided on the fpso gas will be used for fuel or reinjected to boost
recovery shuttle tankers will collect the crude oil and ship to international
markets gross estimated capital expenditure costs remain unchanged at
us5 billion premier will fund its share from rising cash flows
on 1 november premier formally became operator of all of the licence
interests previously operated by rockhopper thereby becoming the
operator of the sea lion development project a new dedicated project
team is undertaking detailed planning of development drilling and the
specification and sourcing of production facilities prior to commencing
frontend engineering design notably an fpso market enquiry which
included visits to ship yards has been undertaken to assess options of
conversions or new builds to meet the design life criteria technical reviews
have also been undertaken to study the option of gas lift instead of hydraulic
submersible pumps while design studies of flow line systems have been
completed health safety and environmental management plans are being
set to safeguard the development and operations phases concept selection
is targeted for mid2013 while project sanction is planned for mid2014 with
first oil targeted for third quarter of 2017 once onstream the sea lion

since the announcement of the farmin in july 2012 premier has been working
closely with rockhopper to define the prospect inventory within its acreage in
the north falklands basin to date we have technical agreement on a
programme of between three and six exploration wells for the next drilling
programme which is targeted for 201415 subject to rig availability wells
currently included in the proposed programme include playopening wells
targeting prospects beneath the existing sea lion sands prospects from
independent feeder systems along the east flank of the basin as well as sea
lion lookalike prospects
premier has received notification from the falkland islands government that
licences pl023 and pl024 premier interest 60 per cent have been extended
to november 2013 pending further seismic interpretation work and that
licences pl003 and pl004 premier interest 45 per cent have been extended

our key asset in indonesia remains the operated natuna sea block a
with both further development and exploration activity in the area
we are planning to build on our existing strong share of the singapore
gas market through our interests in block a aceh and an ongoing
programme of exploration new venture work we are seeking to take
advantage of our longestablished relationships and gas marketing
expertise to increase our incountry presence production and development 
during 2012 the premieroperated natuna sea block a block a sold an
overall average of 217 billion british thermal units per day bbtud gross
2011 161 bbtud from its gas export facilities a 35 per cent increase due to
a fullyear of production from the new gajah baru facility and the established
anoa field
the anoa facility continued to increase its market share of sales under the
first gas sales agreement gsa1 delivering 75 per cent over its contractual
market share of 369 per cent in addition three anoa development wells
were drilled and put on production in 2012 adding 36 million standard cubic
feet per day mmscfd of gas deliverability the nonoperated kakap block
contributed a further 33 bbtud gross 2011 42 bbtud gross liquids
production from the block a anoa field was steady at an average 2400 bopd

the pelikan and naga projects also on block a were sanctioned in april 2012
and are now in full execution mode the contract for the engineering
procurement construction and installation of two wellhead platforms and
connecting pipelines was awarded in may 2012 the two projects will involve
drilling six new development wells to develop an expected 150 bcf of gas
reserves first gas will be delivered in 2014 to supply existing indonesia and
singapore sales contracts
in parallel a major brownfield development project to upgrade the
compression facilities on the block a anoa gas production facility has also
progressed through its first phase in 2012 two cantilever deck extensions
housing a new gas compressor and turbine generator were fabricated and
installed on the anoa platform 2013 will see a second major offshore
campaign during which the existing compression equipment will be
reconfigured for low pressure production the project when complete in
september 2013 will extend the field plateau for another three years and
develop 200 bcf of gross field reserves
on the nonoperated block a aceh work continued on the gas development
project the focus has been on improving the economics such that the
project can be sanctioned by yearend the tendering process for most
facilities is complete with current efforts towards securing higher gas prices

premier carried out exploration in five production sharing contracts psc
in indonesia natuna sea block a kakap tuna block a aceh and buton
in 2012 premier drilled three exploration wells on its indonesian acreage
one of which was successful and opened up a new play
the anoa deep1 well drilled as an exploratory tail to the anoa wl5x
development well discovered gas below the anoa field the well flowed
over 17 mmscfd of gas from fractured sandstones of the lama formation
building on strong share
of singapore gas market the discovery of gas in the lama sands provides additional gas resources that can be
dedicated to existing gas sales agreements and opens up a new proven play type which can
be pursued across premier’ s block a and adjacent west natuna areas prospect development
continued in natuna sea block a with the overall prospect inventory being upgraded
through seismic reprocessing on selected prospects and prospect development in the newly
proven lama play premier expects to start to drill out these prospects in 201415
the biawak besar1 well on natuna sea block a was drilled to test a stratigraphic trap which
was assessed on seismic data to have a good possibility of containing gas biawak besar1
encountered good reservoir development and gas shows but was not deemed commercial
in the buton psc premier participated in the benteng1 exploration well which was aimed
at discovering oil in limestone reservoirs in the cretaceous tobelo formation while the well
was successful in proving an oil presence in the area with oil shows in the miocene tondo
limestones no commercial oil accumulation was found premier and partners will not
continue exploring in the buton psc and the licence will be relinquished shortly
in the block a aceh psc in northern sumatra the matang1 exploration well was spudded
in late november 2012 the objective of the matang1 well is to discover gas resources in a
miocene peutu limestone reservoir the drilling of the top seal sequence has taken longer
than expected with the results now anticipated by the end of march 2013
in 2011 exploration wells gajah laut utara1 and belut laut1 were drilled in the tuna psc
to test the miocene and oligocene potential of two prospects the wells did not find
commercial hydrocarbons but utilising the information gained two new prospects kuda
laut and singa laut were matured in 2012 these prospects are approved for drilling in 2013
with the kuda laut1 and singa laut1 wells expected to spud in the second half of the year
during the year premier maintained an active programme of exploration new ventures work
aimed at capturing new licences this work entailed a number of regional basin studies as
well as three formal joint studies carried out in conjunction with the indonesian government

premier was awarded four new exploration licences in january 2012
as a result of the awards in predefined areas apa 2011 round and
continued to mature a number of prospects towards drill decisions
in 2013 the company also built on its acreage position in and around
the mandal high area through the acquisition of three operated
licences which completed in february 2012 and the award of the skala
exploration licence in the apa 2012 round in addition the company
increased its interest in the bream field development and the adjacent
block at attractive pricing development 
in august premier acquired a 20 per cent interest in pl407 which contains
the bream field and a 40 per cent equity interest in the adjacent pl406
licence this increased premier’s share in the bream project to 40 per cent
and the company’s operated interest in pl406 which contains the mackerel
oil discovery and the herring exploration prospect to 80 per cent premier
paid an upfront consideration of us10 million with further payments of up
to us175 million contingent upon certain milestones being reached
engineering studies for the subsea systems and wells for bream were
completed during 2012 but the studies carried out for the lifetime extension
and upgrade of the fpso targeted for the field demonstrated that the
vessel was not suitable the joint venture partnership has investigated
alternative production facility options and a new build vessel has been
identified commercial negotiations are under way with the contractor for
this vessel and it is expected that front end engineering studies will start in
the second quarter of 2013
during 2012 premier completed subsurface evaluations for the mackerel
discovery based on the results a subsea tieback to the bream fpso is the
most economic solution an exploration well on the adjacent prospect
herring is also planned to be drilled as part of the development project
project sanction and submission of development plans to the authorities
for the bream development are expected in early 2014 first oil is targeted
for 2017 with an initial production rate of approximately 14000 boepd net
to premier
elsewhere in norway commercial discussions have been held with field
owners in the frøy area with the intent of developing a central processing
hub for a number of discoveries close to frøy this has proved a slow
process however the pace is expected to pick up in 2013 with equity
alignment discussions taking place with the operator of a nearby field
active exploration exploration 
work continued in 2012 to evaluate the grosbeak discovery in pl378 the
partnership is participating in an area forum that is evaluating the best way of
developing the resources in the area in addition a significant oil discovery
skarfjell was made in the adjacent licence in 2012 current mapping indicates
that a significant portion of skarfjell extends into pl378 and preparations for
appraisal drilling have been initiated
in february 2012 premier completed its acquisition of three operated
exploration licences these licences are close to premier’s existing freki licence
and are on the margin of the mandal high in the southern norwegian north
sea evaluation of this acreage has so far resulted in a drill recommendation
being brought forward to our partners in pl539 and we are awaiting a decision
shortly premier built further on its acreage position in and around the mandal
high through the apa 2012 licensing round in which it was awarded a 20 per
cent operated interest in the skala exploration licence in january 2013 as a
result premier now has access to around 200 mmbbls of net prospective
resources on and around the mandal high

natural decline in production from our producing fields in pakistan
has again been more than offset by successful infill drilling and
stepout exploration further potential will be tested during 2013
premier is also seeking through a programme of pilot wells at
kadanwari to test the tight gas potential in deeper horizons production and development 
average working interest production in pakistan during 2012 was 15600 boepd net to
premier three per cent higher than in 2011 15100 boepd despite the start of natural
production decline in some existing wells the higher production was mainly due to
successful infill drilling and the tiein of exploration and development wells in the kadanwari
and bhitbadhra gas fields
production from the qadirpur gas field was broadly stable in 2012 averaging 3700 boepd
net to premier compared to 3750 boepd in 2011 this was due to the good performance
of the wellhead compressors and to the better than expected support from the extended
reach wells drilled in the northern part of the reservoir specifically the development wells
qp44 qp45 qp46 and hrl6 were successfully drilled completed and tiedin to
production in 2012 while qp48 and qp49 are currently being drilled in addition the
government of pakistan has approved a new price for qadirpur gas increasing it by 11 per
cent applicable with effect from december 2012
production from the kadanwari gas field averaged 2600 boepd net to premier during 2012
27 per cent higher than in 2011 this was as a result of sustained production from k19 and
the increase in field production following the tiein to facilities of the successful exploration
wells k27 and k28 and the k29 development well
the pilot programme at kadanwari to test the tight gas potential in the lower goru
formation is ongoing the k3 dirb vertical well has been tested and is currently being
tiedin to the facilities while the testing of the k1 dira vertical well commenced in january
six tight sand intervals were fracked and tested separately at the k3 dirb well with total
initial flow of 34 mmscfd which reduced to 18 mmscfd upon clean up this proved that all
the tight intervals in the kadanwari area can flow gas after fracking while the gsand and
bsand have demonstrated relatively better flow potentials these two intervals are being
tested in the k1 dira well where preliminary results are encouraging as the gsand flowed
05 mmscfd prior to clean up all fracked bsand intervals also flowed gas to the surface
while rates are likely to improve after further rigless clean up the gsand will be targeted
in the k31h horizontal pilot well in 2013
the zamzama gas field produced 5800 boepd net to premier during 2012 2011 5800 boepd
this was mainly due to continuous good performance of frontend compressors and the
zam8 infill well being tiedin ahead of schedule subsurface studies were completed in
early 2012 following which two infill wells zam 8 and zam 9 were drilled backtoback in
the second half of the year while the zam8 infill well was tiedin to the system in
november first gas from the zam9 infill well was achieved in january 2013
production from the bhitbadhra gas fields was stable in 2012 averaging 3500 boepd net
to premier this was mainly due to the successful drilling and tie in of the badhra b north1
exploration well in addition the bhit15 development well which was spudded on
4 november was tiedin to the facilities in january 2013 further helping to offset the natural
decline from the existing wells on the bhitbadhra gas fields
a revised development plan for the zarghun south gas field was submitted to the pakistan
government in may 2012 following certification of 64 bcf of tight gas in the dunghan
formation and 12 bcf of conventional gas in the chiltanmughalkot formations by
independent consultants degolyer and macnaughton the revised development plan has
been approved for application of premium ‘tight gas policy’ prices and as a result the joint
venture commenced development work on the project early in 2013 all costs pertaining to
premier’s 375 per cent interest in the project are carried by the operator

following this better than expected result two more wells are planned in 2013 in the eastern
part of the existing lease
the bbn1 well was drilled in september 2012 and made a significant gas discovery in the
kirthar foldbelt the well was drilled to a total depth of 2450 metres and encountered a new
sand interval 44 metres thick in the mughalkot reservoir formation which tested gas at a
flow rate of 31 mmscfd the well was tiedin to the bhit facilities in november the joint

be the successful execution of these projects we will also pursue
exploration opportunities where the balance of risk and reward
meets inhouse objectives production and development 
production from premier’s uk fields increased to 12100 boepd compared to 10300 boepd
during 2011 despite no contribution from the kyle field the banff fpso which handles kyle
production was damaged during exceptionally bad weather at the end of 2011 since then
it has been off location while repairs are undertaken the increased production in the north
sea can be attributed to significantly higher uptime at the balmoral facility positive results from
the scott field well intervention programme and our increased stake in the wytch farm asset
production from premier’s balmoral area averaged 4500 bopd during 2012 compared to
3750 bopd in 2011 an active year of work culminated in a highly successful health safety and
environment hse kp4 audit during august in which a significant improvement in overall
integrity was noted safety performance at the premieroperated balmoral floating production
vessel also improved in 2012 with a marked reduction in incident frequency and severity
at the end of 2011 premier increased its equity in the wytch farm field to 301 per cent
upgrades to the process plant and improvements to management systems have facilitated
increased production efficiency an infill drilling programme commenced in february 2012
ahead of schedule and has resulted in the completion of three new wells and seven workovers
on the huntington field the six well development programme was successfully completed
in july 2012 with three of the four producers coming in above expectations the fpso
voyageur spirit sailed away in september and all five risers have subsequently been
installed adverse weather conditions late in the fourth quarter delayed the commissioning
and installation programme however the dsv polaris is nearing completion of the final
subsea tiein in preparation for first oil which is anticipated by the end of march
on the rochelle project the subsea pipeline and umbilical installation programme and
upgrades to the host scott platform were successfully progressed in 2012 the east rochelle
well the first of the two development wells was damaged during a north sea storm in
february 2013 as a result drilling operations were suspended safely pending further analysis
and the order of the development wells was reversed with the prospect rig spudding the
west rochelle well in february first gas from the rochelle field is now expected either at
the end of the second quarter or in the third quarter of 2013
significant progress was achieved on our ukoperated development assets premier was

in january 2012 premier completed its acquisition of encore oil plc which resulted in the
company taking over operatorship of the catcher project and increasing its stake in the
project to 50 per cent the development concept which was formally approved by the joint
venture in december consists of a leased fpso with subsea tiebacks the project has now
entered the design phase and the tender process with the fpso providers and for the
subsea facilities front end engineering and design feed is under way the design phase is
expected to be completed in the third quarter of 2013 and it is anticipated that the

strong production growth exploration 
in 2012 premier drilled seven exploration wells in the uk north sea primarily
focused on extending the successes of previous years’ drilling in the catcher
licence across a wider area of the central north sea basin this resulted in
success with the carnaby well the first well drilled to date on the western part
of the catcher block which encountered 51 feet of net oil in excellent quality
sandstones the remaining uk exploration wells that targeted this play in 2012
were either dry or encountered noncommercial discoveries as a result the
strategy will now focus exclusively on the prospectivity within the greater
catcher area in particular the bonneville well spudded in early march with the

in addition to bonneville premier will drill one other well lacewing in the uk
central north sea in 2013 lacewing is targeting triassic reservoirs and is
premier’s first high pressure high temperature hpht well in 2012 premier
transferred a 372 per cent interest in block 2322b to conocophillips in
exchange for a carry for the lacewing well as a result premier’s retained equity
in the well is 202 per cent the well which will be drilled using the maersk

in the 27
th
uk licensing round the company was awarded a total of 12 licences
six operated building on our acreage position in the uk north sea in particular
premier was awarded four operated licences adjacent to the catcher area
which offer both nearfield and deeper exploration potential in addition
premier reached an agreement with encounter oil the former management
team of encore oil plc jointly to pursue several mesozoic prospects and leads
primarily in the inner moray firth premier also secured a nonoperated licence
interest in the west of shetland basin it is anticipated that the leads and
prospects identified on this newly captured acreage will be matured during
2013 with drilling in 2014 and beyond

in vietnam we are focused on
optimising production from the
chim sáo field and bringing 
onstream the nearby dua field
we also look forward to the
ca voi exploration well a
potential playopener for the
underexplored phu khanh basin”
“

there is much still to be gained from optimisation of the chim sáo
and nearby dua oil fields we will continue to test the prospectivity
on block 0703 to the south of chim sáo and look forward to
the ca voi exploration well in the first half of 2013 a potential
playopener for the underexplored phu khanh basin production and development 
the premieroperated chim sáo field was brought onstream at the end
of 2011 and the first fullyear of oil and gas production from the field was
accomplished safely 2012 production from the field averaged 15200 boepd
net to premier ahead of the original development plans the price of oil
cargoes sold from the field during the year averaged in excess of us450 per
barrel bbl over brent 
the chim sáo development drilling programme which comprised nine
producing wells and six injection wells was completed safely and under
budget in april 2012 this programme was followed by three additional
wells aimed at capturing upside resources identified during development
two wells were targeted at a fault terrace to the north west of the field one
was successful and commenced production at approximately 3000 bopd
in august the second well targeting a separate fault segment to the north
was dry separately a third well was drilled to accelerate production from
a shallow reservoir with larger reserves than initially evaluated and was
brought onstream in september at a rate of about 2000 bopd
the chim sáo field is currently producing 30 thousand barrels of oil per day
kbopd some 5 kbopd ahead of expectation at sanction with potential for
further increases to deliverability when power constraints currently impacting
the fpso are resolved the plan is to add power generation capacity to
allow the water injection pumps to sustain reservoir pressure at higher
production levels and the compressors to export higher volumes of
associated gas
the development of the premieroperated dua oil field as a three well
subsea tieback to the chim sáo facilities received partner sanction in the
second quarter of 2012 and prime ministerial approval in august installation
of the main pipeline commenced in february 2013 the field which is forecast
to average a gross production rate of 810 kboepd in the first 12 months
is expected onstream in 2014

in july 2012 premier agreed to farmin to the origin energyoperated block 121
in the northern part of the underexplored phu khanh basin offshore central
vietnam for a 40 per cent working interest the farmin received government
approval in february 2013 premier will pay its participating interest share in the
drilling of the high risk ca voi prospect which is planned for may 2013 the
prospectivity of block 121 centres on the untested oligocene play fairway which
premier recognises as being geologically similar to the cau formation that it
has successfully explored in blocks 12w and 0703 in the nam con son basin
immediately after the high risk ca voi well the ocean general will move to drill

new country entry – exploration
2012 highlights and achievements 
• acquired 5000 square kilometres of new 3d seismic
across the western part of our kenya acreage
• successful entry into southern iraq one of the
world’s most prolific basins
• gained a significant acreage position in the relatively
undrilled highly prospective north falklands
basin through the acquisition of 60 per cent of
rockhopper’s licence interests
• in total added in excess of 1 bnboe of gross
unrisked prospective resources through new
country entry
andrew lodge
exploration director
premier is building an increasingly
material exploration programme
our biggest achievement in 2012
was to rebalance the portfolio
through the addition of in excess
of 1 bnboe of gross unrisked
prospective resources through
new country entry we continue
to look for opportunities in new
countries which meet our criteria
of delivering playopening
opportunities with significant
followon potential”
“

in addition to exploration in the existing business unit areas
premier looks to open up new frontier geographies in targeted
new countries where the geology is assessed to be similar to that
of the existing business units where premier has built expertise the acreage recently accessed by premier in new areas is dominated by
deepwater environments where an exploration success has the potential to
transform the resource base of the company to date premier has exposure
to frontier exploration acreage in selected areas of africa and the middle
east we continue to evaluate new areas for potential entry in 2013
in east africa premier has equity interests in two blocks offshore kenya

in late 2012 a prospect inventory is being prepared with a view to drilling
the first exploration well in 2014 or potentially in the fourth quarter 2013
in november 2012 premier was formally awarded a 30 per cent nonoperated
interest in iraq’s block 12 block 12 an 8000 square kilometre block in the
foreland of the zagros fold belt up dip from producing fields lies in a frontier
part of one of the world’s more prolific oil and gas basins the forward plan
on block 12 is to reprocess the existing seismic data in 2013 and then acquire
new seismic data in 2014 subject to the interpretation of the new seismic an
exploration well will be drilled in 2015 or 2016
in egypt following the drilling of the cherry prospect in the north red sea1
licence in 2011 premier has decided to relinquish its equity share of the
licence premier has also withdrawn from the south darag block in the gulf
of suez due to the lack of formal government approval of the licence award

boosted by favourable prices for our chim sáo crude in the asian markets premier’s
average realisations for the year were us1114bbl 2011 us1119bbl influenced by
the timing of actual crude oil liftings after taking into account the effect of hedging
contracts this reduced to us1075bbl 2011 us896bbl

indonesia remained stable increased marginally in the uk and were significantly
reduced in vietnam due to oneoff production start up costs in the prior year underlying
unit amortisation excluding impairment rose to us164boe 2011 us138boe
reflecting increased production from vietnam which has a higher amortisation charge
per boe compared to the group average
exploration expense and prelicence expenditure costs amounted to us1577 million

the group tax charge for 2012 is us1079 million an effective tax rate of 30 per cent of
our profit before tax the group’s theoretical tax rate is close to 50 per cent a higher
taxation rate in the uk being offset by lower rates in vietnam and pakistan the 2012 tax
charge is reduced as a result of a deferred tax credit in the uk arising from the ring
fence expenditure supplement rfes allowance and the small field allowance for the

the initial payment was us231 million in cash in addition premier will pay an
exploration carry of up to us48 million and subject to field development plan
approval a development carry of up to us722 million premier has also agreed to
provide additional standby funding to complete the project in the event that
rockhopper chooses to draw down on this facility premier will take an enhanced share
of entitlement production and cash flows from the sea lion and related fields this
enhanced share continues until premier realises a 15 per cent post tax internal rate of
return on its investment thereafter cash flows are shared prorata to equity interests
premier’s investment in sea lion and related fields will be funded from a combination
of premier’s existing cash resources and facilities and future cash flow from operations

financial risk management
commodity prices
the board’s commodity pricing and hedging policy continues to be to lock in oil and
gas prices for a proportion of expected future production at a level which ensures that
investment programmes for sanctioned projects are adequately funded where
investment requirements are well covered by cash flows without hedging it is recognised
that there may be an advantage in periods of strong commodity prices in locking in a
portion of forward production at favourable prices on a rolling forward 1218 month basis
at yearend therefore 30 million barrels of dated brent oil were hedged through
forward sales for 2013 at an average price of us1090bbl this volume represents
approximately 25 per cent of the group’s expected liquids entitlement production in
2013 48000 metric tonnes mt of hsfo which drives our gas contract pricing in
singapore was subject to collars covering the period to mid2013 with a cap of
us500mt equivalent to around us85bbl an additional 96000 mt have been sold
under monthly forward sales contracts for 2013 at an average price of us657mt these
two hedges cover approximately 32 per cent of our expected indonesian gas working
interest production for 2013
during 2012 embedded oil price collars and forward oil sales of 39 million barrels
and fuel oil collars and forward sales for 246000 mt expired at a cost of us607 million
2011 us1191 million which has been offset against sales revenue
oil hedge collars are incorporated within the pricing terms of physical off take agreements
avoiding the requirement to revalue them for accounting purposes a credit of
us96 million 2011 us280 million occurred in respect of past marktomarket
provisions for oil hedges which have now fully expired
foreign exchange
premier’s functional and reporting currency is us dollars exchange rate exposures relate
only to local currency receipts and expenditures within individual business units local
currency needs are acquired on a shortterm basis during the year the group recorded
a gain of us15 million on such shortterm hedging 2011 loss of us04 million in 2012
the group also issued €250 million longterm senior loan notes which have been
hedged under a cross currency swap in us dollars at a fixed rate of us1328€
interest rates
although the group’s borrowing facilities are defined in floating rate terms a majority
of its current drawings have been converted to fixed interest rates using the interest rate
swap markets on average therefore the cost of drawn bank funds for the year was
46 per cent marktomarket movements on these interest rate swaps amounted to
us25 million 2011 charge of us64 million which was credited to other comprehensive
income
cash balances are invested in shortterm bank deposits and aaa rated liquidity funds
subject to board approved limits and with a view to spreading counterparty risks
insurance
the group undertakes a significant insurance programme to reduce the potential impact
of physical risks associated with its exploration development and production activities
business interruption cover is purchased for a proportion of the cash flow from producing
fields for a maximum period of 18 months due to exceptionally bad weather in
december 2011 the banff fpso – which handled kyle production – lost its anchors and
the risers were severely damaged stopping kyle production for the foreseeable future

business risks 
premier’s business may be impacted by various risks leading to failure to achieve
strategic targets for growth loss of financial standing cash flow and earnings and
reputation not all of these risks are wholly within the company’s control and the
company may be affected by risks which are not yet manifest or reasonably foreseeable
effective risk management is critical to achieving our strategic objectives and protecting
our assets personnel and reputation and therefore premier has a comprehensive
approach to risk management
a critical part of the risk management process is to assess the impact and likelihood of
risks occurring so that appropriate mitigation plans can be developed and implemented
risk severity matrices are developed across premier’s business to facilitate assessment of
risk the specific risks identified by departments project teams corporate functions and
business units are consolidated to provide an oversight of key risk factors at each level
from operating level through business unit management to executive committee and
the board
for all the known risks facing the business premier attempts to minimise the likelihood
and mitigate the impact according to the nature of the risk premier may elect to
tolerate risk treat risk with controls and mitigating actions transfer risk to third parties
or terminate risk by ceasing particular activities or operations premier has a zero
tolerance to financial fraud or ethics noncompliance and ensures hses risks are
managed to levels as low as reasonably practicable whilst managing exploration and
development risks on a portfolio basis
the group has identified its principal risks for the next 12 months as being
• health safety environment and security hses
• production and development delivery
• exploration success and reserves addition
• host government – political and fiscal risks
• commodity price volatility
• organisational capability
• joint venture partner alignment and
• financial discipline and governance

key performance indicators
premier measures its performance in line with its strategic objectives of growing the
value of the underlying assets of the business and creating significant returns for
shareholders specifically key performance indicators kpis are used to measure
progress against agreed targets in the areas of safe responsible and sustainable
operations growth through exploration development production and acquisitions
and maintaining financial strength these kpis also link to senior management’s
remuneration
operating safely responsibly and sustainably 
premier is committed to operating responsibly in every part of the business success in
these areas inherently protects our assets our revenue streams and our reputation
health and safety performance is measured using total recordable injury rate trir per
million manhours and near miss high potential incidents hipo per million manhours
safety performance data includes both premier employees and contractors
premier’s trir performance improved in 2012 as the company sought to improve
performance by reinforcing procedures and standards frequent training and ongoing
communication a trir of 18 per million manhours was achieved in 2012 which
is below the trir target of 20 
as part of its safety performance management process premier tracks hipos which
include any event that might lead to significant injury environmental damage property
damage or security breaches premier continues to ensure that key lessons are learned
and disseminated for all hipos and companywide safety alerts are issued citing key
causes and preventative actions required premier’s hipo performance while still within
the target of 20 hipos per million manhours declined in 2012 2012 saw eight hipos
which equates to a frequency rate of 13 hipos per million manhours the 2013 target
is 15 hipos per million manhours
building the strong production base 
one of the metrics by which premier’s growth performance is measured is by the
compound annual growth rate in net asset value per share premier targets in excess of
10 per cent nav growth per share per year and over the sevenyear period to end2012
the company has achieved in excess of 15 per cent
premier also aims to build on the existing production base in order to sustain and
continue to deliver growth this is measured using daily average production and the
number of development projects being brought through to sanction average daily
production increased 43 per cent in 2012 to 577 kboepd due to a fullyear of production
from the new asia fields chim sáo and gajah baru which came onstream in late 2011
premier is targeting average production of 6570 kboepd for 2013 and a run rate of
100 kboepd once the catcher project comes onstream

premier’s production goal is underpinned by the pipeline of
development projects being progressed across the portfolio and
the ability to commercialise and bring onstream these projects is
key to the company’s success in 2012 premier sanctioned four
development projects solan pelikan naga and dua
delivering growth 
premier looks to create future growth through exploration in
focused geologies and valueled acquisitions progress towards
this growth ambition is measured by reserves replacement risked
prospective resource added and finding costs
premier also undertakes acquisitions to access additional resources
in 2012 the company acquired 60 per cent of rockhopper’s
licence interests in the falkland islands including the sea lion
project and increased its stake in the bream project to 40 per
cent through a sale and purchase agreement with skeie energy
as exploration successes which included the carnaby discovery
in the uk north sea and badhra b north1 and k30 in pakistan
also added to premier’s reserve and resource base
reserves and resources increased 51 per cent to 773 mmboe
giving a reserve replacement ratio of 138 per cent in addition
2012 saw premier add approximately 250 mmboe of contingent
resources and in excess of 15 billion barrels of unrisked
prospective resources to its portfolio
premier added reserves and resources through exploration and
acquisition at an average cost of around us2bbl during 2012
maintaining financial strength
one of premier’s strategic objectives is to maintain financial
strength in order to invest in the future of the business and deliver
significant returns to shareholders 2012 was another strong year
with record profit after tax of us2520 million an increase of 
47 per cent and operating cash flow of us8082 million an
increase of 66 per cent
premier’s portfolio of crudes was sold at an average of
us1114bbl realised average gas prices a significant portion of
which tracks oil price movement achieved us834mscf in 2012
operating costs were stable in 2012 at us162boe rising cash
flows along with successful bank and bond market transactions
provide premier with the funding required for future growth
ability to add new capital and sufficient covenant headroom are
measured to ensure the company has the funds to meet forecast
cash requirements and maintain liquidity throughout the cycle

our dealings premier oil plc 2012 annual report and financial statements   33
human rights
in 2012 premier conducted a review of its human rights policy
against best practice standards such as the united nations
guiding principles on business and human rights and the position
of our peers in the oil and gas sector 
our revised policy more explicitly recognises the moral reputational and operational value of respecting
and promoting human rights both inside and outside of our company it includes the need to 
• engage with stakeholders in our efforts to respect and promote these rights
• recognise the development and cultural rights of external stakeholders as basic human rights
• recognise our responsibility to respect the rights of indigenous people in all countries where we operate
• help prevent manage and resolve conflict where we are in a position to do so
• ensure we are in no way involved or associated with the issue of forced involuntary or child labour
• ensure our security practices do not undermine the human rights of local communities
• encourage joint venture partners to adopt the principles in this policy
• consider withdrawal from relationships with business partners where there is no evidence that they are
moving towards the application of international human rights standards and
• use our legitimate influence to promote human rights outside our areas of operation 
our human rights policy is based on the fundamental rights set out in the universal declaration of human
rights and is guided by those rights enshrined in the core labour conventions of the international labour
organisation and by the united nations global compact principles our policy addresses the rights of our
employees including their health and safety as well as their security arrangements and working conditions
and the development rights of our external stakeholders in particular local communities
further detail on our performance and alignment with this policy is included in the corporate responsibility
report 2012 there were no reported violations of our human rights policy in the review period 34   premier oil plc 2012 annual report and financial statements

health and safety
premier is committed to operating responsibly and will never knowingly
compromise our health safety or environmental standards to meet our
operational objectives our goals are to ensure the safety of everyone
involved with our operations and to protect the environment premier oil plc 2012 annual report and financial statements   35
in 2011 we introduced and communicated our golden rules the golden rules reinforce the hses policy
associated procedures and standards and have been established to help prevent the most common causes
of serious incidents in our industry continued implementation of the golden rules during 2012 has been a
key part of our commitment to excellence and continuous improvement in health and safety performance
premier continues to ensure that every employee contractor and individual at our operations understands
company rules and expectations every employee is accountable and has a personal responsibility for
health safety and environment employees are also expected to ‘stop the job’ if they see or believe
something can be better controlled or is unsafe
premier has been certified to ohsas 18001 and iso 14001 since 2004 for global drilling and since 2006 for
our indonesian production operations in 2012 we completed a number of ohsas 18001 and iso 14001
surveillance audits on our production and drilling operations during 2012 drilling anoa and balmoral
production retained their certifications and gajah baru was added to the scope of our indonesian
production operations certificate our chim sáo production operation in vietnam is working towards
ohsas 18001 and iso 14001 certification in 2013
occupational safety performance
in 2012 we worked 61 million manhours 2011 72 million manhours this decrease on the previous 
year was due to reductions in drilling manhours from 17 million in 2011 to 08 million in 2012 and in
construction from 28 million in 2011 to 20 million in 2012 most of these manhours 43 million vs 
59 million in 2011 were worked by contractors on our operations we expect to see a progressive 
increase in manhours during 2013 with a number of new projects continuing and coming into the
construction phase

total recordable injuries
our overall trir performance improved significantly from 24 in 2011 to 18 in 2012 showing a continued
improvement in performance over the last three years and meeting our 20 target trir performance at our
construction operations was exceptional at 00 2011 18 much improved at our production operations at
28 2011 61 but poor at our drilling operations at 75 2011 00 this overall positive trend in our trir
performance was largely due to significant improvements at our north sea operations where rates improved
from 94 in 2011 to 45 in 2012 following a series of sitespecific safety initiatives and leadership courses to
address the previously high number of mostly minor accidents including slips falls and finger injuries at our
production facilities our operations in asia continued to perform well with a trir score of 09 2011 15
our trir target for 2013 is 20 
process safety performance
insight into high potential incidents hipos and their rate of occurrence enable us to learn about how to
mitigate future incidents often by addressing the root causes we believe these hipos act as a leading
indicator of potential injury and complement the continued testing of asset integrity through our project

corporate responsibility report continued
high potential incidents
last year saw a slight increase in hipos per million manhours from 08 in 2011 to 13 in 2012 this was well
within our target of 20 the increase in rate from 2011 was due to a significant decrease in the number of
manhours but a small increase in the number of high potential incidents from six in 2011 to eight in 2012
seven of which occurred at our asia operations performance improved at our construction operations
where there were zero high potential incidents in 2012 2011 one all of the eight high potentials reported
in 2012 were investigated indepth corrective actions identified and their implementation monitored safety
alerts based on each incident were made available to all employees in order to share learning across the
group safety alerts are mandatory for all hipos but may also be issued where there are incidents or events
that require heightened awareness and caution our hipor target for 2013 is 15
loss of primary containment
measurement of loss of primary containment lopc is a new metric proposed by the international
association of oil and gas producers ogp we recognise further work is required to harmonise process
safety performance measurement across the industry and continue to work with ogp as members of its
process safety subcommittee to develop an industry approach to indicators and reporting that includes
leading metrics it is anticipated ogp will publish the first lopc industry data in 2013 and that this will be
able to be used to set future premier targets
in 2012 there were 41 lopc events 2011 35 at our operations of these none were tier 1 lopc events
2011 one there were seven reported tier 2 events 2011 five the remaining minor events 34 included
small gas leaks and contained oil spills that did not reach the environment tier 1 events are those where
there is a significant loss of containment from a process system ie gas over 500kg and oil over 1000kg
outdoor tier 2 are those releases of lesser consequence ie gas over 50kg and oil over 100kg outdoor
and some events defined by american petroleum institute api we measure the number of incidents or
rate per activity manhour lopcr at both our operated drilling and production operations and sum it as
a company metric
safety by design
premier has integrated process safety protocols into the psrs of all its projects these reviews provide
assurance that material hse issues have been identified and are being effectively managed throughout the
project lifecycle a typical project lifecycle will require six strategic reviews as a project moves from concept to
construction and then to operation these psrs align with our project approval gates at which time strategic
decisions are made to either progress a project further towards the operations stage or to delay or divest
safety cases are in place at all of our operated installations this safety case regime is aligned with the
regulated standards in the united kingdom we believe this represents best practice and we are committed to
implementing such cases at all of our operated production facilities worldwide even when not required by the
local regulatory regime a safety case is developed during the early stages of a project and becomes more
detailed as a project nears the operation stage a safety case must be in place before production commences
each case includes a review and impact assessment of the relevant process safety risks the requirement to
meet established safety benchmarks and the adoption of further steps to reduce risks to a level that is as low
as is reasonably practicable the alarp principle for our operating assets these are reviewed every five
years to ensure continued compliance safety cases are reviewed by either the local regulatory authority or
a competent independent third party to provide assurance that they comply with our standards  premier oil plc 2012 annual report and financial statements   37
environment
environmental assessment management and reporting forms a
major part of premier’s hse risk management process we conduct
baseline surveys and environmental and social impact assessments
for each new operated activity
this involves an assessment of the physical socioeconomic and biological environments including the
rights of indigenous peoples and biodiversity we measure and review each impact in turn and gauge both
its significance and how it can be reduced to a level that is as low as is reasonably practicable potential
actions to improve environmental performance are screened based on cost duration and impact to
determine which are feasible for implementation we periodically review these environmental impacts and
actions for our existing facilities to ensure we are complying with our policy of continuous improvement
environmental indicators and targets
we report our environmental performance in line with the ipieca oil and gas industry guidance on
voluntary sustainability reporting 2010 and to meet gri sustainability reporting guidelines our emissions
performance is benchmarked by contributing our data to an industry database compiled and published by
the ogp  as an oil company with production facilities in the north sea we also comply with the european
union emissions trading scheme and submit an annual externally verified report on our emissions profile
to the department of energy and climate change decc we also participate in the carbon disclosure
project where we achieved a carbon disclosure score of 66 out of 100 in 2012 2011 66

climate change and greenhouse gas emissions
greenhouse gas emissions associated with hydrocarbon combustion at our operations amounted to 
890809 tonnes in 2012 2011 615000 tonnes this increase in total emissions was largely due to a full year
of production from our gajah baru and chim sáo operations in asia versus only a limited number of months 
in 2011
our operated emissions intensity decreased from 305 tonnes per thousand tonnes of production in 2011 to
242 in 2012 this was mainly due to reduced flaring at chim sáo versus 2011 additional contributing factors
included a reduction in development drilling and increased overall production from both our asian and north
sea assets our anoa and gajah baru facilities in indonesia delivered strong performance with an average
intensity of 175 tonnes per thousand tonnes of production 2011 139 tonnes and 119 tonnes per thousand
tonnes of production 2011 228 tonnes respectively our performance at gajah baru was lower than the
159 tonnes industry average published by ogp  despite the overall reduction of around 20 per cent we failed
to meet our intensity target mainly due to unexpected flaring at chim sáo in vietnam 
we calculate our greenhouse gas co

e emissions both for operated assets and on an
equity basis for production across our global portfolio greenhouse gas intensity from flaring and fuel gas
combustion associated with our full equity portfolio amounted to 170 tonnes per thousand tonnes of

spills and discharges
the total volume of produced water discharged from our operations in 2012 amounted to 3905611 tonnes
2011 2055878 tonnes over 90 per cent of the total was produced by our north sea operations with the
increase in 2012 being largely due to the balmoral field after a period of shutdown in 2011 the average oil
in produced water decreased slightly from 139 parts per million weight ppmwt in 2011 to 100 ppmwt in
2012 this decrease in the oil concentration of produced water was mainly due to a reduction at balmoral that
averaged 103 ppmwt 2011 140 ppmwt the average concentration of oil in produced water discharged
by our anoa facility in indonesia also reduced to 107 ppmwt from 133 ppmwt in 2011
in 2012 there were 13 spills to the environment 2011 20 spills 11 of these were hydrocarbon spills 2011
16 spills eight of which were upsets of the produced water system at balmoral in the north sea the largest
of these was three barrels 2011 54 barrels the total volume of spills amounted to 08 tonnes 2011 27 tonnes
100 per cent 2011 90 per cent of which was associated with spills at our production operations there were
zero hydrocarbon spills at our drilling activities in 2012 we maintain oil spill contingency plans for each of our
operations and have ongoing contracts with oil spill response specialists to provide support in the unlikely
event of a major incident two other chemical spills occurred at our drilling operations in 2012 2011 four
spills totalling 002 barrels and 0002 tonnes 2011 13 tonnes premier oil plc 2012 annual report and financial statements   39
it also includes the need to 
• maintain timely constructive and transparent ongoing engagement with all stakeholders
• treat neighbours with respect and understanding acknowledging community governance and seeking

mr j darby was called to approve the detail of arrangements approved in principle by a prior scheduled meeting of the remuneration committee 
executive committee and management structure
the board has delegated the daytoday running of the group to the chief executive who has established an executive
committee exco to assist him in this role
during the year the structure of exco was enhanced with the creation of three new roles
• the role of director business units was created to manage performance of all business units and ensure coordination with
the functions the creation of this role has removed the need for a layer of management at the regional business unit level
• the role of strategy and commercial manager was created to ensure that the group’s longer term strategic needs are
properly addressed and
• the role of corporate services director was created to bring together a number of the critical service functions
the responsibilities of exco include the development of group strategy for approval by the board portfolio management and
the delivery of performance against the targets set by the board 
delegation of authority 
responsibility levels are communicated throughout the group as part of corporate accounting and through an authorisation
manual which sets out inter alia delegated authority levels segregation of duties and other control procedures this manual
was updated in 2012 to reflect the new organisational structure and the increased size of the group
board performance evaluation
the board believes that there is benefit in the periodic involvement of an independent external facilitator in the annual board
evaluation process as this brings independent perspective it has been the board’s practice to engage such an external
facilitator every two years and in normal circumstances an externally facilitated evaluation would have taken place in 2012
however as the board spent considerable time on strategic issues in 2012 it was decided that an external evaluation will be of
more value next year when the new strategy and organisation have bedded down and thus an internal evaluation process was
carried out in 2012
the board and committee evaluations were facilitated by the chairman the evaluation comprised a series of questions on
major issues which were used as the basis for the onetoone interviews by the chairman with all directors the interviews
covered a number of key areas including strategy succession planning board size and composition the roles and
responsibilities of the board and its committees risk management and the relationship between the board and management
the results of the reviews were considered by the chairman and the committee chairmen and were then discussed with the
relevant committees and collectively by the board as a whole 
the performance of individual nonexecutive directors was evaluated by the chairman with input from the committee chairmen
and the other directors the performance of the chief executive and other executive directors was evaluated by the chairman
and nonexecutive directors 
no major issues arose from the evaluation process and the directors have concluded that the board and its committees operate
effectively recommendations were made to further enhance the performance and effectiveness of the board and a process of
continuous improvement led by the chairman is in place
44   premier oil plc 2012 annual report and financial statements
corporate governance report continued induction information and support 
new directors receive a full induction to the company this consists of information covering the operations of the board as well
as meetings with the board chief executive and other executive directors all nonexecutives have direct contact with the
company’s senior management between board meetings and also visit the company’s operations in order to familiarise
themselves with its activities and to meet and engage with staff shareholders are given the opportunity to meet with new
directors upon request or at the next annual general meeting agm following their appointment the company has directors’
and officers’ liability insurance in place and details of the policy are given to new directors on appointment formal procedures
are in place to enable individual board members to take independent advice where appropriate 
conflicts of interest
a director has a duty to avoid a situation in which he or she has or can have a direct or indirect interest that conflicts or
possibly may conflict with the interests of the company formal procedures are in place to ensure the board’s powers of
authorisation of conflicts or potential conflicts of interest of directors are operated effectively the board determined that during
2012 these procedures were enforced and adhered to appropriately
risk management and internal controls in premier
the corporate governance process in premier is designed to determine the nature and level of risk that the company is willing
to take in pursuit of its strategy and to ensure that any risks taken are soundly managed and that the system of internal controls
is effective any system of internal control can provide only reasonable and not absolute assurance that material financial
irregularities will be detected or that the risk of failure to achieve business objectives is eliminated 
business management system
internal controls within premier are governed by the business management system bms this system is composed of the
policies standards procedures processes and guidelines for every function required to carry out premier’s business including
risk hses corporate social responsibility operations exploration business development finance and other business
support services corporate group functional management systems are complemented by local management systems within
the business units which are designed to supplement corporate policies standards procedures processes and guidelines with
those specifically required in order to operate and manage the business under local conditions and in compliance with local
laws and regulations
the bms is designed to manage rather than eliminate the risk of failure to meet our business objectives the effectiveness
of the bms is a function of both the adequacy of the system and compliance with the system premier’s audit and review
programme includes specific scope to review adequacy of and compliance by component business unit and functional
management systems at appropriate regular intervals 
the annual cycle of monitoring in premier culminates in the completion of declarations by business unit and functional
management confirming compliance with the group’s bms as well as identifying enhancements as part of a continuous process
for improvement of the effectiveness of management systems
risk management
premier believes that risk management is just part of good management which leads to quality decision making and
achievement of targets for growth of the business the risk management process is central to premier’s bms 
since the appointment of a group audit and risk manager in 2010 premier’s risk management system has been further
developed in accordance with the risk management principles and guidelines of iso 31000 risk management – principles and
guidelines the processes developed by the company cover all key elements of iso 31000

core process risk management continued
in early 2012 det norske veritas dnv carried out an assessment of the extent to which premier’s risk management system
is aligned with iso 31000 and found that premier had a well structured system of risk management that was strongly aligned
the core process for risk management lies at the heart of the system framework
this core process is used to manage the spectrum of risks which premier face from strategic geopolitical and other external
risks to operational financial and organisational risk
the context for risk management is established by development and communication of strategy growth targets team
performance deliverables and kpis 
a systematic process for identification and assessment of risk is undertaken across the company business units and functions
regular workshops are undertaken with input from independent consultants with specialist knowledge and from dialogue with
our partners to assist with risk identification and assessment and risks are reviewed on a regular basis to ensure that new risks or
exposures as a result of changes in the business or the business environment are captured 
a standard matrix of impact versus likelihood is used to assess risks at all levels in the organisation appropriate consideration is
given to risk dependency and amalgamation of similar specific risks across the organisation risks are categorised according to
a scale of major medium minor and escalated to the appropriate level
risk treatment includes risk acceptance or tolerance and active risk reduction measures risk appetite objectives are defined
and action plans are implemented particular attention is given to safety and environmental factors to ensure that residual risks
are at a level that is as low as reasonably practical 
the status of risks and progress with risk treatment plans are monitored continuously and reviewed periodically via
performance reviews workshops audits and risk assessments
the architecture of the organisation provides the framework for defining the accountability and responsibility for risk
identification and management and links the board and audit and risk committee to the executive committee and functional
and business unit management structure and enables risks to be escalated and managed at the appropriate level the group
audit and risk manager is responsible for the risk management system and the overall running of the process 
the risk protocols are the policy procedures and processes documented as part of the risk management system and key tools
used in the process the corporate risk register is the primary tool for risk management in premier the register is a webbased
tool which is updated at regular intervals the register facilitates recording of functional and business unit risks together with
their assessment definition of existing and new treatment plans for control and mitigation and assignment of responsibility at
the appropriate level in the organisation
a cycle of continuous improvement to the risk management system within the organisation is adopted and regularly reviewed
with both the executive committee via regional and functional performance reviews and the audit and risk committee 
as already noted premier’s risk management process has been developed significantly over the past three years in accordance
with the risk management principles and guidelines of iso 31000 initiatives are in hand to further embed risk management in
the group’s culture and business processes

david lindsell
chairman of the audit and risk committee activities during the year continued
more specifically the responsibilities of the committee were discharged as follows
• the committee reviewed the group’s risk management process designed to identify and mitigate the key risks facing the
group there is an ongoing process of refinement and embedding of risk management best practice through the group 
in accordance with the principles and guidelines set out in iso 31000 in particular following the positive findings of the
external review carried out by det norske veritas in early 2012 the committee noted improved reporting of findings and
implementation of control improvements arising from reviews of the risk management and internal control systems these
measures will continue to be developed and reported on to the committee through 2013 and beyond we intend during

of risk management process in the group
• the corporate risk register crr is the principal record of information about identified risks and the controls in place to
mitigate them at departmental assetproject business unit and corporate function levels ongoing development and
refinement of the crr during 2012 has enabled risks and mitigating processes to be described more completely and the
programme of financial and operational control reviews to be prioritised further against the most significant group business
risks as ranked in the crr crr functionality has also been improved to allow risks assessed to have a preselected potential
impact which can be measured in terms of effect on net present value or other severity of consequence to be flagged and
referred automatically up to the next levels in the organisation enabling more effective topdown monitoring of risk
• some 36 reviews of aspects of risk management and internal controls in operations and corporate functions were carried
out during the year in reviewing the findings from these reviews the committee noted with approval that reporting had
become more directed towards the group’s major risks allowing the committee to focus on the key issues and challenges
facing the group recommendations to improve internal controls andor to mitigate risks were agreed with the relevant
business unit or corporate function management after each review and progress in implementing the recommendations was
monitored by the group audit and risk manager

carry out the programme of review in addition the group obtains independent confirmation of the effectiveness of internal
controls from a variety of external sources including joint venture and governmental financial and operational audits 
• the committee reviewed the 2012 halfyear and fullyear financial results announcements and draft 2012 annual report

financial statements in particular section 1 directors’ report performance to assess whether the narrative is consistent
with the accounting information in the financial statements
• the fee proposals for the external audit and halfyearly review were considered and agreed and the committee reviewed

premier oil plc 2012 annual report and financial statements   49 group audit and risk function
we reported last year that the role of group audit and risk manager which was created in 2010 had evolved to the point where
the committee believed that the company had a function substantially equivalent to internal audit the group audit and risk
function has developed further during 2012 and the committee now considers it to be fully equivalent to an internal audit
function the committee approves the appointment or termination of appointment of the group audit and risk manager
external auditor
deloitte llp deloitte was initially appointed as external auditor of the company in 2004
the committee regularly reviews the issue of the independence of the external auditor this review considers the overall
relationship between the auditor and the company based on feedback from the company’s finance team and from the auditor
and the nature and extent of nonaudit services provided by the auditor and takes account of the safeguards established by the
auditor against loss of audit independence including rotation of the audit partner and other key members of the audit team
the committee believes that in certain limited circumstances nonaudit work may be carried out by the external auditor the
allocation of nonaudit work is considered by reference to the company’s policy on the provision of nonaudit services by the
auditor which can be found on the company’s website this policy is aimed at ensuring their continued independencethe use
of the external auditor for services relating to accounting systems or financial statements is not permitted nor are various other
services which could give rise to conflicts of interest or other threats to the auditor’s objectivity that cannot be reduced to an
acceptable level by applying safeguards the committee believes that there is nonaudit work such as certain assurance and
advisory services that may be best performed by the auditor as a result of their unique knowledge of the company any material
nonaudit work of this nature requires approval by the committee the policy and overall fees paid to our auditor are also
reviewed on an annual basis by the committee
deloitte are required to confirm to the committee that they have both the appropriate independence and objectivity to allow
them to continue to serve the members of the company the committee also requires the external auditor to confirm that in
providing nonaudit services they comply with the ethical standards for auditor issued by the uk auditing practices board
this confirmation was received for 2012
in accordance with the ethical standards for auditor the audit engagement partner rotates at least every five years the
current audit engagement partner is david paterson who has been in the role since the auditor’s limited review of the 2012
halfyear results
the committee reviews the expertise performance and effectiveness of the auditor on the basis of the reviews carried out
the committee recommended to the board that it should propose the reappointment of deloitte as the external auditor of
the company

audit and risk committee report continued premier’s business may be impacted by various risks leading to failure to achieve strategic targets for growth loss of financial
standing cash flow and earnings and reputation not all of these risks are wholly within the company’s control and the company
may be affected by risks which are not yet manifest or reasonably foreseeable
effective risk management is critical to achieving our strategic objectives and protecting our personnel assets the communities
where we operate and with whom we interact and our reputation premier therefore has a comprehensive approach to risk
management as set out in more detail in the corporate governance report
a critical part of the risk management process is to assess the impact and likelihood of risks occurring so that appropriate
mitigation plans can be developed and implemented risk severity matrices are developed across premier’s business to
facilitate assessment of risk the specific risks identified by departments project and asset teams business units and corporate
functions are consolidated and amalgamated to provide an oversight of key risk factors at each level from operations through
business unit management to executive committee and board level
for all the known risks facing the business premier attempts to minimise the likelihood and mitigate the impact according to
the nature of the risk premier may elect to take or tolerate risk treat risk with controls and mitigating actions transfer risk to
third parties or terminate risk by ceasing particular activities or operations premier has a zero tolerance to financial fraud or
ethics noncompliance and ensures that hses risks are managed to levels that are as low as reasonably practicable whilst
managing exploration and development risks on a portfolio basis
the key risk factors identified from this approach are represented in the matrix below and the accompanying table summarises
their potential impacts and our approach to managing them the assessment of the impact and likelihood takes into account

company secretary
20 march 2013 dear fellow shareholder
on behalf of the board i am pleased to present the 2012 directors’ remuneration
report for which we are seeking approval from shareholders at our annual 
general meeting 
the remuneration committee aims to ensure that our remuneration policy serves
shareholder interests and closely reflects the group’ s business strategy the committee is
mindful of the need to demonstrate the link between remuneration and performance and
to incentivise its employees t o this end premier operates a similar philosophy to pay
throughout the organisation and all employees including executive directors receive
awards under the same incentive schemes thus ensuring groupwide focus on common
business goals
during 2012 the committee undertook a full review of the executive remuneration
arrangements at premier taking into account shareholder views from the 2011
consultation the company’ s strategy market practice and evolving best practice
guidelines the review concluded that
• the pay mix being heavily weighted towards longterm variable elements is in the best interests of shareholders as it ensures
a longterm focus direct alignment with shareholders and a highly performanceoriented culture
• the annual bonus based on a corporate scorecard capturing financial operational and strategic objectives helps reward
shorterterm objectives key to achieving our longterm strategy
• the long t erm incentive plan ltip ensures alignment with shareholders being based on both absolute and relative t otal
shareholder return tsr and measured over a total of six years
• the significant deferral requirement of vested ltip equity pool and ltip performance share awards helps support staff
retention and lengthens the incentive time horizon
• against our comparators total cash ie salary plus bonus for our executive directors is below market the ltip is geared to
provide the opportunity to achieve above market levels of pay only through exceptional sustained relative tsr performance
over six years and
• the review of the company’ s underlying performance before ltip payouts are finalised ensures that the impact of external
factors are taken into account where appropriate the committee reviews a range of measures and not just those specified
in the plan to ensure this assessment is robust 
as a result of the review the committee concluded that the aims and structure of the remuneration packages are embodied in
the existing policy and therefore it remains appropriate for 2013 
the ltip is structured so as to reward both absolute and relative share price performance thereby directly aligning the interests of
executives and shareholders over the 2010 ltip cycle ending in december 2012 even though premier’ s absolute share price
performance was positive at 51 per cent pa the ltip equity pool threshold of 10 per cent pa was not met and consequently
no awards were earned for this element over the same period however premier’ s relative performance against its sector peers
was strong at just below upper quartile and consequently 2010 ltip performance share awards and 2010 ltip matching share
awards will partially vest in early 2013 at approximately 90 per cent and approximately 65 per cent of maximum respectively as
detailed later in the report the committee also considered the underlying performance of premier over the threeyear period
and concluded that the performance merits the awards made
remuneration issues across all sectors continue to be in the spotlight t o stay ahead of requirements we have incorporated a
number of changes in this report consistent with the draft proposals that have been tabled by the department for business
innovation  skills bis during 2012 however as set out in the notice of annual general meeting this year there will continue to
be a single advisory vote on this report 
on behalf of the board i would like to thank shareholders for their continuing support
yours sincerely

responsibly for their contributions remuneration packages are intended to be sufficiently competitive to attract retain and
motivate individuals of the quality required to achieve the group’s objectives and thereby enhance shareholder value the

structured such that the greater part of total remuneration is delivered through longterm sharebased incentives to ensure
maximum alignment with shareholders these schemes provide a clear link between pay and performance ensuring that
superior remuneration is paid only if superior performance is delivered over a sixyear period

premier oil plc 2012 annual report and financial statements   61 executive director pay mix
the charts below illustrate the potential reward opportunities for executive directors for ‘low’ ‘median’ and ‘stretch’
performance see below for assumptions on performance scenarios based on longterm incentive grants made in 2012
remuneration is significantly geared towards performanceoriented pay with particular emphasis on longterm performance
for example at ‘median’ performance approximately 54 per cent of the ceo’s remuneration package is delivered through
variable components rising to approximately 90 per cent at ‘stretch’ performance the maximum value is delivered only if upper
quartile tsr is delivered against sector peers over six years with a requirement for upper decile performance in the last three
years the charts also include the actual remuneration delivered to the executive directors in respect of performance for 2012
for comparison

the above increases are lower than the average increases across the group’s operations of five per cent
the committee will continue to review salaries annually to ensure they remain appropriate particularly given the current highly
competitive talent market in this sector and the fact that it is critical to the company’s future success that we retain key talent annual bonus scheme 
in line with previous years executive directors participate in nonpensionable bonus arrangements the committee sets yearly
targets on the basis of a balanced scorecard comprising kpis and other corporate objectives payout is determined with
reference to the balanced scorecard after careful assessment by the committee and subject to the committee’s discretion
based on a broader assessment of overall company performance bonuses for executive directors are subject to a maximum 
of 100 per cent of base salary 
for executive directors and other senior management any annual bonus earned above 50 per cent of salary is deferred in
shares for three years deferred bonus shares remain subject to a ‘bad leaver’ provision annual bonus awards are subject to a
clawback provision in the event of a material misstatement of the company’s financial results gross misconduct or error in the
calculation of performance conditions
2012 annual bonus outcome 
in assessing 2012 performance the committee has taken into account the various measures of the five criteria below against
specific targets targets were set at the beginning of 2012 and designed to be stretching but achievable the exact targets
are not disclosed for reasons of commercial sensitivity however performance in relation to threshold base and stretch levels 
is detailed

in addition to the achievement against specific targets the committee considered the wider overall company performance 
and awarded annual bonuses of 45 per cent of salary to the executive directors
the 2013 annual bonus structure is broadly similar to that used for 2012 but with nav growth now included in addition a new
element based on personal objectives will be included with a 20 per cent weighting 
long term incentive plan ltip
all employees participate in the company’s ltip  approved by shareholders at the 2009 agm thereby encouraging a focus
throughout the company on longerterm performance and alignment with shareholders 
the ltip is structured to reinforce the delivery of strong share price growth and relative stock market outperformance over the
longterm performance is assessed over a minimum of three years and over six years including the matching scheme vesting
is based on a combination of the absolute change in the company’s equity value per share and the company’s relative total
shareholder return tsr ie share price plus dividends performance against peers 
during the year the committee reviewed the choice of performance measures and in particular the sensitivity of tsr to
changes in oil price the committee concluded that tsr remains an appropriate performance measure as it rewards the
delivery of the company’s strategy and also aligns management’s interests with those of shareholders absolute tsr captures
the absolute return delivered to shareholders and relative tsr measures performance on a relative basis thereby helping to
negate the impact of uncontrollable factors such as oil price movements on the reward delivered through the ltip  
premier oil plc 2012 annual report and financial statements   63 long term incentive plan ltip continued
to optimise the link between reward and performance the plan allows the committee certain discretions on determining the
outcome of the ltip  based on its assessment of the company’s underlying financial and operational performance the
committee may 
• reduce the size of the equity pool
• allow for the equity pool to be fully funded when growth in equity value exceeds 20 per cent pa
• lift the cap of 100 per cent of salary under the equity pool
• decide whether or not to grant matching shares and
• reduce the level of vesting for performance shares and matching shares
in assessing the underlying performance of the company the committee has previously considered performance against the
five metrics noted below which are specified in the plan as a result of the review undertaken in 2012 the committee has
broadened the ‘inputs’ used to determine whether the tsr performance is reflective of the company’s underlying financial and
operational performance and from 2013 will also consider other measures such as net asset value per share finding and
development costs per barrel delivery of the strategy and relative tsr

operating cash flow 
earnings per share growth 
health and safety record 
further all ltip awards are subject to clawback in the event of a material misstatement of the company’s financial results gross
misconduct or material error in the calculation of the performance conditions 
awards under the ltip comprise three elements
equity pool awards vest after a threeyear performance period and are based on a share of a pool which is subject to
annualised growth in the company’s equity value per share the vested award is delivered in
shares and 50 per cent of the vested award is deferred for a further three years
performance share awards vest after a threeyear performance period based on the company’s tsr relative to a comparator
group of international oil and gas companies 50 per cent of the vested award is deferred for a
further three years
matching awards deferred equity pool awards and performance share awards are eligible for a matching award of
up to 25 times the number of shares deferred vesting after a further three years based on the
company’s tsr relative to a comparator group of international oil and gas companies

granted in 2013 will also be based on this structure

the value of the ltip equity pool is based on the growth in the company’s equity value per share over the performance period
see below if the company’s compound annualised growth is equal to 10 per cent per annum one per cent of the growth will
be credited to the ltip equity pool for growth of 20 per cent per annum or more 25 per cent of the growth will be credited
for growth of more than 10 per cent but less than 20 per cent between one per cent and 25 per cent of the growth will be
credited on a straightline basis all employees are eligible to participate in the ltip equity poolthe value of an entitlement is

ltip vesting outcomes in 2012
the 2010 ltip award cycles completed their threeyear performance periods on 31 december 2012 as follows
• 2010 ltip equity pool cycle over the performance period the company’ s market capitalisation increased from £13417 million
to £18227 million equivalent to growth in equity value per share of 51 per cent per annum after including a £2500 million
adjustment to reflect the increase in the company’s share capital as a result of the acquisition of encore in january 2012
as a result awards under the 2010 equity pool will not vest as the threshold was not met 
• 2010 ltip performance share cycle over the performance period the company’s tsr relative to its peers was between the
median and upper quartile warranting vesting of 899 per cent and
• 2010 matching award cycle matched over deferred shares granted in 2010 under the aep 2007 award over the
performance period the company’s tsr relative to its peers was between the median and upper quartile warranting a
matching ratio of 164  1
the committee is satisfied that the recorded tsr is reflective of the underlying performance of the company in assessing the
underlying performance of the company the committee took into account amongst other factors the company’s earnings per
share growth cash flow return on invested capital reserve replacement and health and safety record as shown below
