2006 began well for star energy with the 
humbly grove gas store being handed over  
to the customer vitol sa for full customer 
nominations on 1 february 2006
with slow progress towards obtaining planning 
permission for further gas storage capacity 
2006 has consequently been very challenging 
following the refusal of lincolnshire county 
council to grant permission for our welton 
gas store despite a recommendation from 
local planning officers the company took the 
decision to adopt the gas act 1965 for future 
gas storage applications although this new 
approach has required significant extra work 
and resources including extensive dialogue 
with the department of trade and industry 
dti the company believes that it provides 
greater certainty of planning application 
timelines we will continue with our strategy 
of progressing multiple gas storage projects 
simultaneously and 2007 will see our first 
planning submissions under this legislation 
further gas storage capacity remains critical to 
ensuring security of gas supply to householders 
in the coming winters and we will continue 
to need clear direction and support from 
central government to ensure the timely 
commissioning of this capacity 
as a company operating onshore in the uk 
often in quiet rural areas star energy expended 
considerable time and effort in 2006 on 
engaging local communities and stakeholders 
in our plans we will continue with our 
efforts to provide greater transparency and 
understanding of the impact of our operations 
on these communities the benefits of what 
we are doing and how we seek to mitigate the 
impact on their environment in some cases 
strong local concerns have caused us to rethink 
our options for well and plant locations adding 
considerably to the project cost however we 
believe that our flexibility of approach will help 
build sustainable longterm relationships with 
these communities
during 2006 we explored other opportunities 
to move our business towards our strategic 
goal of being a multisite gas storage operator 
these included both offshore uk and nonuk 
western european opportunities with the 
company having entered into a joint venture  
to evaluate the possibility of converting the 
north sea forbes field into a gas store with  
up to 50 bcf of capacity
we strongly value the support of our investors 
and remain committed to increasing the 
value of their investment through the delivery 
of new gas storage capacity the board and 
management expect to report real progress 
with this during 2007 and we are examining all 
options to deliver value to shareholders from 
our existing asset base
on behalf of the board i would like to thank 
our management and staff for their hard work 
and support in 2006 and we look forward to 
the challenges of 2007

chief executive’s review
2006 was in many ways a year of  
learning for star energy 
humbly grove gas storage facility
a major milestone for the company was 
passed on 1 february 2006 when the 
humbly grove gas store was handed 
over to the customer vitol sa for full 
customer nominations the gas store has 
performed broadly in line with expectations 
the humbly grove gas store is the third 
largest in the uk and has made a material 
contribution to security of supply the 
dispute with the epc contractor amec  
was resolved commercially
gas storage planning activities
despite fears of a gas supply shortage 
during february and march 2006 and 
a parliamentary statement of need for 
additional gas infrastructure including gas 
storage the difficulties in obtaining planning 
permissions for the company’s new gas 
storage projects continued in relation to the 
welton gas storage project the time from 
submission of the company’s applications 
to final determination was 29 months 
planning permission was refused on final 
determination despite a highly detailed 
planning officers’ report recommending 
approval the company initiated an appeal 
against the refusal but decided to withdraw 
the appeal when it became clear that 
lincolnshire county council intended to raise 
procedural objections that could have been 
raised within the 29 month determination 
period as a result of that experience and 
following dialogue with the company’s 
advisors and the dti the company decided 
to adopt the gas act 1965 as the standard 
platform for all of its future gas storage 
planning applications although this 
legislation requires increased application 
detail and additional resources the company 
believes applications under the gas act 1965 
will provide enhanced certainty of planning 
application timelines
recognising the need to engage local 
stakeholders and provide increased 
transparency in the preparation of planning 
applications the company is committed 
to increasing local dialogue via liaison 
panels and adopting a flexible approach to 
development planning t o achieve this the 
company is expanding its planning resources 
and adopting minimal impact developments 
including remote siting of plant and 
equipment and extended reach drilling this 
was exemplified by the decision to drill an 
appraisal well from the company’s existing 
well site at albury in surrey rather than create 
a new well site in an area of outstanding 
natural beauty this will involve the drilling 
of an extended reach well the true vertical 
depth of the well will be circa 4000 feet but 
the total well path will be in excess of 14000 
feet in order to reach the required targets 
since this well path is beyond the capabilities 
of the company’s previously contracted 
drilling rig an agreement has been entered 
into for the lease of a new state of the art 
hydraulic rig from the company’s associate 
and nominated drilling contactor larchford 
limited this rig will not only be more 
powerful but will also be quieter than 
other commercially available rigs
new opportunities
the company has been actively seeking  
new gas storage development opportunities 
this together with an increase in awareness 
of the company’s unique capabilities in 
operating oil and gas fields and developing 
and operating depleted reservoir gas storage 
facilities has led to the company being  
invited to collaborate on a number of new 
storage developments 
one such project relating to the north 
sea forbes field in block 438 concerns the 
potential development of a new offshore gas 
storage facility this project a joint venture 
with encore oil for which star energy will 
provide the gas storage development lead 
will augment the company’s onshore gas 
storage projects initial modelling indicates 
forbes could be converted into a gas store 
with a capacity of up to 50 bcf the 
company is scheduled to complete a 
feasibility study by the end of 2007 
during 2006 the company increased its 
continental european involvement with 
participation in an onshore denmark 
exploration well the well was a dry hole  
but data is being evaluated to ascertain 
whether there are gas storage possibilities 
in addition gas storage opportunities were 
evaluated in the netherlands and italy this 
work is ongoing
other operating activities
the company continued the successful 
integration of pentex the onshore uk  
oil and gas business acquired in august
2005 benefiting from both the addition  
of incremental oil and gas production and  
at least one new gas storage project the  
65 bcf storage project at gainsborough 
a development well at the stockbridge oilfield 
was brought into production in june 2006
at an initial rate of over 1000 bopd the 
company was on track to achieve its  
oil production targets until a spate of 
well pump failures exacerbated by the  
late delivery of a work over rig caused 
production to fall in the fourth quarter 
conclusion
with continued strong cash flow from oil 
production as well as from the humbly 
grove gas storage facility the company 
will continue to invest heavily in the 
development of its six gas storage projects in 
the uk and pursue gas storage opportunities 
across continental europe the company is 
confident that 2007 will yield positive results 
in relation to the planning and permitting 
efforts expended during the course of 
2006 and is convinced that its increased 
investment in gas storage development will 
provide an attractive longterm return to 
shareholders

star energy at a glance
with 156 employees we 
own and operate the  
10 bcf gas storage 
facility at humbly 
grove and 26 oil and 
gas fields in the weald 
basin and the east 
midlands areas of  
the uk 
our portfolio of onshore uk fields 
includes five potential gas stores  
which we are actively developing
to the planning application stage
we have recently acquired an 
opportunity to assess the viability
of a depleted offshore gas field for
gas storage purposes
gas storage
the fundamentals for additional gas storage in the uk remain 
firm with increasing import dependence in the context of uk gas 
storage capacity as a percentage of annual demand well below 
our european peers 
star energy remains focussed on developing those fields in its 
portfolio which have geology suited to gas storage with current 
development activities on albury phase 1 gainsborough welton 
and bletchingley our intention is to contract future gas stores  
to blue chip customers securing a stable base cash flow while  
retaining the ability to share in the upside in the longer term  
if wintersummer gas price differentials widen
oil  electricity 
star energy continues to be the second largest onshore oil and 
gas producer producing 4595 boepd for 2006 the produced gas 
is used to generate electricity
the portfolio of 26 oil and gas fields provides the group with  
a strong cash flow helping to fund the development of the 
group’s gas storage opportunities our strategy is to continue  
the development of this portfolio to maintain the associated  
cash flow

gas storage qa
safety is the primary 
concern in the operation of 
our business if the storage 
of natural gas in depleted 
oil and gas reservoirs 
was not safe star energy 
would not be proposing its 
development 
how safe is natural  
gas storage
q1
by design our gas storage 
plants have a minimal 
impact on the environment 
what is the environmental 
impact of gas storage
q2
click to return to contents 09 star energy group plc annual report and accounts 2006
oil and gas occurs naturally having been 
created millions of years ago by the burial 
of organic matter the oil and gas has since 
been held under pressure in the minute 
pores of certain rocks several thousand feet 
beneath the earth’s surface the volume 
of porous rock holding the oil and gas is 
referred to as a reservoir above the reservoir 
is a layer of cap rock which is impervious 
and prevents the oil and gas from escaping 
to the earth’s surface the fact that the oil 
and gas has been contained within the 
reservoir for such a long time is testament 
that the reservoir provides reliable pressure 
containment if this were not the case the 
oil and gas would have long since escaped
drilling into the reservoir and extracting oil 
and gas reduces the residual quantity of oil 
and gas in the reservoir and the pressure 
under which it is held creating what is 
termed a depleted reservoir it is the depleted 
reservoir which provides the capacity for 
gas storage by injecting natural gas back 
into the depleted pores a situation which 
previously existed naturally is reproduced 
of course gas storage involves extracting 
gas out of as well as injecting gas into 
a reservoir thus changing the pressure 
within the reservoir t o ensure that such 
pressure changes do not affect the integrity 
of the porous rock or the cap rock checks 
are undertaken by independent expert 
consultants
so how do we ensure safety during  
the operation of a gas store
we make certain that no uncontrolled release 
of natural gas can occur from the reservoir 
pipes or gas plant through our design 
construction and operating procedures 
design the design of a gas store is 
fundamental to its safety we use well 
established international engineering codes 
and standards for the design of the plant 
pipelines and wells incorporating safety 
margins in all areas of the operation we 
conduct rigorous hazard identification 
and risk assessments which consider 
every conceivable failure and require the 
minimising of all identified risks to an 
acceptable level 
construction during the building process 
quality checks are undertaken at all stages 
to ensure that a gas store is constructed 
as designed and that the design standards 
have been applied the plant and pipelines 
are proof tested using water at pressures 
well in excess of any that will be experienced 
during operation and all emergency systems 
are rigorously tested 
operation documented operating 
procedures are adhered to by trained staff 
and preventative maintenance systems are 
employed to undertake regular servicing of 
the plant ensuring its integrity at all times 
at all stages of a gas store’s design 
construction and operation risk assessments 
are conducted to make certain that at no time 
is safety compromised as demonstration of 
star energy’s commitment towards safety all 
future planning applications for gas storage 
projects will include risk assessments and 
reservoir integrity findings 
environmental impact assessments 
are undertaken by independent expert 
consultants for all of our gas storage 
planning applications proposed sites are 
selected so as to cause minimal impact on 
local communities and to ensure no impact 
on any water resource or flood risk 
permanent aboveground plant is screened 
from public view where necessary with no 
part greater than 165 metres high plant is 
designed to ensure energy efficiency and  
to operate within noise limits set by the 
planning authorities
the construction of a gas store is expected 
to take approximately 18 months during 
which time the plant is constructed 
pipelines laid and gas wells drilled although 
during this time there is an increased 
level of traffic to and from the gas storage 
site schemes are employed to minimise 
the impact on local roads noise levels are 
controlled to prevent nuisance and where 
necessary screening is installed to prevent 
visual disturbance 
a gas store is connected via an underground 
pipeline to the nearest access point to the 
national grid gas network independent 
expert consultants review the proposed 
route of the pipeline to ensure that 
ecological or archaeological sites are avoided 
the land beneath which the pipeline is laid 
is returned to its natural condition once the 
pipeline is in place
in this year’s annual report we are going  
to address a number of questions that  
are often asked about gas storage…

what is star energy  
doing to involve local 
communities in plans for 
gas storage developments
q3
star energy has always 
adopted a proactive 
approach in consulting 
local people parish 
borough and county 
councils early in our plans 
to develop a gas store 
q4
what is the gas act 1965 
and what does it mean for 
star energy
the gas act 1965 the act 
was passed specifically 
to allow for the storage 
of gas in natural porous 
strata such as depleted 
reservoirs and includes 
provisions for the granting 
of planning permission 
to undertake gas storage 
activities 
click to return to contents 11 star energy group plc annual report and accounts 2006
we hold exhibitions in local venues where 
local residents can view our plans and meet 
our senior employees to scrutinise the 
proposals this also enables us to understand 
the local issues and concerns which we 
make a principle of addressing
we welcome regular meetings with local 
communities through liaison panels where 
we can share with them our progress as a 
project goes through the conceptual and 
assessment stage where our pipelines pass 
through a number of different parishes we 
offer to meet parish councils and frequently 
at their request hold exhibitions for their 
parishioners
borough and county councils advise us 
of any local interest groups with whom 
we should consult regarding particular 
information for consideration and inclusion 
in the preparation of the environmental 
impact assessment a key tool in this 
process is the preparation by star energy of 
a ‘scoping report’ which enables the council 
and other consultees to advise on any 
particular aspects we must review
wide consultation is an important and 
integral part in developing our plans allaying 
frequently unfounded local concerns and 
helping us where possible to adjust schemes 
in response to local issues
an application under the act is made 
directly to the energy minister the minister 
who will ultimately determine the merits 
or otherwise of the application the act 
contemplates consultation with the normal 
consultees including local planning 
authorities the health  safety executive 
the environment agency and other 
interested parties regarding the application 
to store gas 
as the act deals specifically with gas storage 
in depleted reservoirs it is key legislation 
for star energy’s gas storage development 
programme the act involves a process of 
consultation with all relevant parties but 
unlike planning applications made under the 
t own and country planning act 1990 to local 
planning authorities the planning application 
process under the gas act 1965 is conducted 
to a schedule controlled by the minister 
thereby avoiding unnecessary delays

1 accounting policies
the following accounting policies have been applied consistently in 
dealing with items which are considered material in relation to the 
group’s financial statements 
basis of preparation
the financial statements have been prepared on a going concern 
basis in accordance with applicable accounting standards and under 
the historical cost accounting rules and in accordance with statement 
of recommended practice ‘ accounting for oil and gas exploration 
development production and decommissioning activities’ 
the group and company have taken advantage of the exemption 
contained in frs 8 ‘related party disclosures’ and has therefore not 
disclosed transactions or balances with entities which form part of 
the group
changes in accounting policies
there have been no changes in accounting policies adopted during  
the year 
basis of consolidation
the consolidated financial statements include the financial 
statements of the company and its subsidiary undertakings  
made up to 31 december 2006 
in respect of subsidiaries controlled indirectly by the company 
through star energy limited its 100 owned subsidiary the 
acquisition method of accounting has been adopted under this 
method the results of subsidiary undertakings acquired or disposed 
of in the year are included in the consolidated profit and loss 
account from the date of acquisition or up to the date of disposal 
under section 2304 of the companies act 1985 the company  
is exempt from the requirement to present its own profit and  
loss account 
investments
in the company’s financial statements investments in subsidiary 
undertakings associates and joint ventures are stated at cost less 
any provision for impairment in value 
consortium accounting
a small proportion of the group’s exploration development and 
production activities are conducted as colicensee in joint operations 
with other companies the financial statements reflect the relevant 
proportions of production capital expenditure and operating costs 
applicable to the group’s interest where a group company is party 
to a joint arrangement which is not an entity that company accounts 
directly for its part of the income and expenditure assets liabilities 
and cash flows such arrangements are reported in the consolidated 
financial statements on the same basis where the group farmsin 
to a farmout agreement it accounts for its proportion of revenues 
costs assets and liabilities in accordance with the provisions of the 
farmout agreement 
associates
associates are undertakings that are not subsidiaries or joint 
ventures over which the group has significant influence and can 
participate in financial and operating decisions investments in 
associated undertakings are accounted for using the equity method 
the consolidated profit and loss account includes the group’s 
share of the associated undertaking’s results while the consolidated 
balance sheet includes the group’s share of the net assets or net 
liabilities of the associate 
intangible fixed assets
i  exploration and evaluation expenditure included here are costs 
which are directly attributable to gaining access rights to areas 
of interest compiling prefeasibility and feasibility studies and 
conducting exploratory activities once capitalised exploration 
and evaluation expenditure is reviewed for impairment at each 
balance sheet date any impairment is charged through the profit 
and loss account if it is decided to develop the areas to which the 
intangible fixed asset expenditure relates the expenditure will be 
transferred to tangible fixed assets
ii  emissions credits the group participates in the eu emissions 
trading scheme this is a ‘cap and trade’ scheme under which 
organisations are awarded emissions credits to cover carbon 
dioxide emissions under this scheme the group receives an 
allocation of emissions credits for each calendar year within a 
phase these emissions credits can be used against carbon dioxide 
production or sold either in the current calendar year or in other 
calendar years within the same phase the emissions credits are 
included in the balance sheet as an intangible fixed asset recorded 
at the market price and exchange rate prevailing on the first day 
of the phase being 1 january 2005 no policy to revalue or mark 
to market has been adopted the group’s actual carbon dioxide 
production against the emissions credits allocation for each year 
is reflected in the profit and loss account together with any profit
loss on credits sold and any cost of additional credits purchased
tangible fixed assets 
the group follows the full cost method of accounting for oil and gas 
operations under this method all expenditure in connection with 
the acquisition exploration appraisal and development of oil and gas 
assets including interest payable exchange differences incurred on 
borrowings in respect of development projects and direct overheads are 
capitalised and accumulated in full cost pools on a geographical basis
cost pools are determined on the basis of the fields possessing to 
a significant degree common characteristics in at least one of the 
following factors geological area interdependence of infrastructure 
common environment or common development of markets
any impairment in the value of the cost pool is charged through the 
profit and loss account as additional depletion where it is considered 
that an impairment of the asset value has occurred
proceeds from the disposal of oil and gas assets are credited against 
the relevant pool any overall surplus arising in the cost pool is 
credited to the profit and loss account
depletion and depreciation
capitalised expenditure within each separate cost pool is depleted 
on a unit of production basis the depletion charge is based on 
estimates of proven and probable reserves the costs of undeveloped 
acreage and exploration assets are excluded from the capitalised 
cost pool to be depleted pending determination of the recoverable 
reserves attributable to such assets 
other tangible fixed assets are stated at historical cost net of 
depreciation and any provision for impairment depreciation is 
calculated on all other tangible fixed assets other than freehold 
land on a straightline basis at rates calculated to write off the cost 
or valuation of those assets less estimated residual value over their 
expected useful life of between three and 25 years

1 accounting policies continued
impairment tests
where there is an indication that the value of an oil and gas cost 
pool may be impaired the net amount at which the pool is recorded 
is assessed for recoverability against the discounted future estimated 
net cash flows expected to be generated from the estimated 
remaining commercial reserves this assessment is made on the 
basis of future oil and gas prices exchange rates and cost levels as 
forecast at the balance sheet date a provision is made by way of 
an additional depletion charge where the carrying value of the pool 
exceeds the discounted future net cash flows to be derived from its 
estimated remaining commercial reserves
decommissioning provision and asset
licensees have an obligation to restore producing fields to a 
condition acceptable to the relevant authorities at the end of their 
commercial lives under frs 12 ‘provisions contingent liabilities 
and contingent assets’ the discounted present value of this future 
cost has been provided for and capitalised within the respective cost 
pool the capitalised cost is amortised through the cost pool on a 
unit of production basis and the increase in the net present value of 
the future cost the unwinding of the discount is included within 
interest payable and other similar charges 
the gas storage assets are considered to have infinite useful economic 
lives and therefore no provision is made annual assessments are 
conducted to support the continuation of this policy 
derivative financial instruments
the group uses derivative financial instruments to reduce its 
exposure to fluctuations in foreign exchange rates interest rates  
and movements in oil and gas prices
premiums paid to enter into such derivative financial instruments are 
charged to the profit and loss account over the period of the hedge 
payments and receipts arising under the financial instruments are 
recognised in the profit and loss account in the same periods as the 
hedged transactions
the group does not hold or issue derivative financial instruments for 
speculative purposes and it is the group’s policy that no trading in 
financial instruments shall be undertaken
foreign currencies
transactions in foreign currencies are recorded using the rate of 
exchange ruling at the date of the transaction or if hedged forward 
at the rate of exchange under the related forward currency contract 
monetary assets and liabilities denominated in foreign currencies 
are translated using the rate of exchange ruling at the balance sheet 
date exchange gains or losses on translation are included in the 
profit and loss account
post retirement benefits
the group operates a defined contribution pension scheme the 
assets of the scheme are held separately from those of the group in 
an independently administered fund the amount charged against 
profits represents the contributions payable to the scheme in respect 
of the accounting year
shortterm incentive plan
the group operates a shortterm incentive plan for executive 
directors and other key managers under the terms of the plan 
annual awards are made to plan participants dependent upon the 
achievement of individual performance targets the performance 
targets are determined by the remuneration committee and 
reviewed annually 
sharebased payments
in accordance with frs 20 ‘sharebased payments’ the group 
reflects the economic cost of awarding shares and share options to 
employees by recording an expense in the profit and loss account 
equal to the fair value of the benefit awarded the expense is 
recognised in the profit and loss account over the vesting period of 
the award
stocks
stocks are stated at the lower of cost and net realisable value 
taxation
the charge for taxation is based on the result for the year and takes 
into account taxation deferred because of timing differences between 
the treatment of certain items for taxation and accounting purposes
deferred tax is recognised without discounting in respect of all 
timing differences between the treatment of items for taxation and 
accounting purposes which have arisen but not reversed by the balance 
sheet date except as otherwise required by frs 19 ‘deferred t ax’  
turnover
turnover is derived from sales of oil electricity and natural gas to 
third party customers and from the rental of gas storage facilities 
forward contracts are sometimes used by the group to hedge the 
price at which oil is sold in such circumstances turnover is recorded 
at the actual hedged amount
turnover relating to oil is recognised when the oil is transferred  
into customer tanks electricity turnover is recognised on a monthly 
basis calculated from meter readings turnover relating to natural 
gas is recognised when the gas is transferred to the customer gas 
storage rental income is recognised in accordance with the relevant 
lease agreement 
gas storage
gas storage facilities are considered to be leased to customers under 
operating leases the total income arising over the duration of the 
contract is recognised evenly throughout the course of the contract 
subsequent to the gas storage asset being completed and becoming 
fully operational 
leases
operating leases and the corresponding rental charges are charged 
to the profit and loss account on a straightline basis over the life of 
the lease
assets under finance leases are included under tangible fixed assets 
at their capital value and depreciated over their useful lives lease 
payments consist of capital and finance charge elements and the 
finance charge element is charged to the profit and loss account
cash
cash for the purpose of the cash flow statement comprises cash  
in hand and deposits repayable on demand less overdrafts payable 
on demand

19 share incentive plans continued
the t otal shareholder return tsr performance conditions of the ltip are as follows 
first tranche shares can vest at the end of a three year performance period commencing on 1 september 2005 if the company’s tsr is in the 
top quartile of companies in the ftse small cap index ‘the index’ the full number of first tranche shares will be received for performance 
between median and upper quartile vesting will occur on a straightline basis so that 25 of the first tranche shares are received for median 
performance and full vesting occurs for top quartile performance no shares will be received if the company’s tsr is below the median in  
that index
receipt of the second tranche shares are subject to the same conditions other than that performance is measured over a four year period 
beginning on 1 september 2005 and no shares can be received until the end of that period
fair value of options
inputs to the valuation model
the fair values of awards granted under the approved share option scheme the ltip and the sharesave scheme have been calculated using 
a variation of the binomial option pricing model that takes into account factors specific to share incentive plans such as the vesting periods 
the expected dividend yield on the company’s shares and expected early exercise of share options the tsr performance condition attached to 
the ltip has been incorporated into the measurement of the fair value by means of actuarial modelling the following principal assumptions 
were used in the valuation

star energy at a glance
with 156 employees we 
own and operate the  
10 bcf gas storage 
facility at humbly 
grove and 26 oil and 
gas fields in the weald 
basin and the east 
midlands areas of  
the uk 
our portfolio of onshore uk fields 
includes five potential gas stores  
which we are actively developing
to the planning application stage
we have recently acquired an 
opportunity to assess the viability
of a depleted offshore gas field for
gas storage purposes
gas storage
the fundamentals for additional gas storage in the uk remain 
firm with increasing import dependence in the context of uk gas 
storage capacity as a percentage of annual demand well below 
our european peers 
star energy remains focussed on developing those fields in its 
portfolio which have geology suited to gas storage with current 
development activities on albury phase 1 gainsborough welton 
and bletchingley our intention is to contract future gas stores  
to blue chip customers securing a stable base cash flow while  
retaining the ability to share in the upside in the longer term  
if wintersummer gas price differentials widen
oil  electricity 
star energy continues to be the second largest onshore oil and 
gas producer producing 4595 boepd for 2006 the produced gas 
is used to generate electricity
the portfolio of 26 oil and gas fields provides the group with  
a strong cash flow helping to fund the development of the 
group’s gas storage opportunities our strategy is to continue  
the development of this portfolio to maintain the associated  
cash flow
