audit of reserves and resource volumes for annual report and accounts of nautical petroleum plc “the company”
at	 your	 request	 we	 have	 examined	 the	 estimates	 as	 of	 reserves	 contingent	 and	 prospective	 resources	 set	 forth	 in	 the	 company’s	 annual	 report	 and	 accounts	 our	 examination	 included	 such	 tests	 and	 procedures	 as	 we	 considered	 necessary	 under	 the	 circumstances	 to	 render	 the	 opinion	 set	 forth	 herein
we	 are	 independent	 with	 respect	 to	 the	 company	 as	 provided	 in	 the	 standards	 pertaining	 to	 the	 estimating	 and	 auditing	 of	 oil	 and	 gas	 reserve	 information	 promulgated	 by	 the	 society	 of	 petroleum	 engineers
it	 should	 be	 understood	 that	 our	 above–described	 audit	 does	 not	 constitute	 a	 complete	 reserve	 and	 resource	 study	 of	 the	 oil	 and	 gas	 properties	 of	 the	 company	 in	 the	 conduct	 of	 our	 report	 we	 have	 not	 independently	 verified	 the	 accuracy	 and	 completeness	 of	 information	 and	 data	 furnished	 by	 the	 company	 with	 respect	 to	 ownership	 interests	 agreements	 relating	 to	 current	 and	 future	 operations	 and	 sales	 of	 production	 and	 likely	 development	 timing	 we	 have	 however	 specifically	 identified	 to	 you	 the	 information	 and	 data	 upon	 which	 we	 so	 relied	 so	 that	 you	 may	 subject	 such	 to	 those	 procedures	 that	 you	 consider	 necessary	 furthermore	 if	 in	 the	 course	 of	 our	 examination	 something	 came	 to	 our	 attention	 which	 brought	 into	 question	 the	 validity	 or	 sufficiency	 of	 any	 of	 such	 information	 or	 data	 we	 did	 not	 rely	 on	 such	 information	 or	 data	 until	 we	 had	 satisfactorily	 resolved	 our	 questions	 relating	 thereto	 or	 independently	 verified	 such	 information	 or	 data

number of blocks as at june 2006 02 nautical petroleum plc report and accounts 2006
the company has made very substantial 
progress since listing on the alternative 
investment market aim in april 2005 
in the process nautical has achieved 
widespread recognition as a focused and 
specialist heavy oil development and 
production company which now holds  
a significant portfolio of reserves 
contingent resources and prospects
nautical has rapidly achieved several of 
its key earlyphase objectives including 
recoverable reserve acquisition 
financial results 
the accounts reflect the prerevenue 
phase with a very modest rate of 
spending which is mainly associated 
with the technical programmes in 
support of licence applications 
preparation for farmout processes and 
prospective acquisition evaluation 
during the period two share placings 
were completed for a total of £18m this 
funding covered the cash portion of 
corporate acquisitions including alba 
resources holdings group through 
which the company secured its 
participation in the mariner heavy oil 
field funds raised have also assured that 
nautical has the means to meet its share 
of projected costs of asset appraisal 
programmes and licence work 
commitments 
nautical continues to apply its stated 
policy of equity financing during the 
prerevenue phase complemented by 
affordable reserve appraisal programmes 
with risksharing through selective  
farmouts
licence activity 
the programme of selective corporate 
acquisition and licence applications has 
led to a greatly expanded portfolio of 
licence participations in the preferred 
area of the east shetland platform this 
area of the north sea is a major heavy oil 
province and therefore a prime target for 
nautical the company also announced 
its first licence participation in onshore 
europe through a farmin to the grenade 
discovery in south west france with 
completion awaiting french government 
approval
a major farmout initiative was 
undertaken during the first half of 2006 
the industry response across the whole 
spectrum from specialists to oil majors 
has underscored the rapidly growing 
interest in heavy oil prospects the 
programme led to the announcement 
during june 2006 of a farmout 
agreement with sk corporation of  
south korea covering four licence  
blocks with completion expected  
in late september 2006 
operator approval 
a further early objective was to have 
nautical approved as an exploration 
operator by the department of trade  
industry dti approval was officially 
confirmed in october 2005 and nautical 
is now qualified to lead asset appraisal 
development projects on united kingdom 
continental shelf ukcs licences where 
this complements the company’s 
strategy 
directors staff and associates 
by any measure nautical has achieved 
much during this period this would not 
have been possible without the 
determination and dedication of the 
executive management as well as  
the valued advice and support of the  
nonexecutive directors
the nautical strategy of outsourcing 
services has led to the creation of close 
relationships with professional associates 
and specialist suppliers whose 
commitment and contribution have 
greatly assisted in the early development 
of the company
outlook 
nautical has established itself as a player 
in the heavy oil arena with an extended 
asset base specialist focus and 
expertise assured funding and 
advantageous market access the 
company is now well placed to progress 
to the production phase 
technological developments and market 
trends continue to favour the profitable 
development and production of heavier 
crude oil in most probable future oil 
market scenarios
the opportunity to work closely with 
chevron and sk corporation on the 
appraisal and development phases of 
offshore fields will add to the capability 
and standing of the company in the 
longer term 
 
nautical has the assets expertise and 
funding to move forward with partners 
into the production phase when the focus 
will shift to the achievement of early 
production and revenue from the 
development of selected reserves

heavy oil 
an overview
the exploitation of heavy oil accumulations in the united 
kingdom continental shelf ukcs is a specialist oil sector 
which is benefiting from a combination of continuing 
technological advances and the rise in crude oil prices in  
the uk the department of trade  industry dti is very 
supportive and is encouraging the industry to develop heavy 
oil discoveries and appraise prospective reserves as a potential 
means to mitigate the decline in north sea crude production 
relatively recent advances in technology 
are the prime factors enabling more 
economic recovery from heavy oil 
reserves continuous improvements and 
related operating experiences have added 
to the attractiveness and value of heavy 
oil reserves not only at present crude oil 
prices in the us60bbl range but also 
down to a mid us20bbl price 
what is heavy oil
there is no definite classification for 
heavy oil but the industry generally 
considers it to be oil with a high density 
5 centipoises cp and low 10  22 
api gravity the specific gravity of crude 
at 60f the oil is “heavy” due to its high 
proportion of heavy hydrocarbon 
fractions
although the api figure is the most  
often quoted oil classification as it is 
more relevant to the refining yield value 
and not the economics of production 
when considering production the  
most significant factor is viscosity 
“thickness“ with heavy oils generally 
being at greater than 5cp at reservoir 
conditions
the producibility of heavy oil relates to 
the viscosity of the oil in the reservoir 
this is often a function of the reservoir 
temperature and the gastooil ratio  
oils with similar apis can have very 
different viscosities
other factors which influence 
productivity include reservoir geometry 
oil column thickness and continuity and 
the permeability of the reservoir
how much heavy oil is there
there have been relatively few studies of 
global heavy oil reserves mainly due to 
problems associated with classification 
however recent research indicates 
estimates of 4600bn barrels in place of 
heavy oils if 15 of this were recovered 
it would equal the current estimated 
lighter crude resources the world’s 
major heavy oil deposits are located in 
canada venezuela and the former soviet 
union fsu
the majority of the heavy oil fields in the 
north sea were discovered during the  
oil boom of the 1970s but technological 
limitations meant that the discoveries 
could not be commercially developed at 
the time the subsequent focus on the 
development of lighter oil reserves in the 
fsu and west africa in the 1980s as well 
as the pattern of oil prices left these 
heavy oil fields undeveloped
heavy oil and the north sea
the development of heavy oil production 
in the north sea is not new existing 
producing heavy oil fields include 
captain 88cp alba 7cp and clair 
20cp the activity and interest 
associated with the appraisal and 
development of ukcs heavy oil has 
accelerated recently 
future development of ukcs heavy oil 
fields will involve a phased development 
approach and application of enhanced 
recovery techniques including extended 
horizontal wells designed to maximise 
rates of recovery
summary
• heavy oil is oil with a high density 
and low api gravity 
 
• estimation of 4600bn barrels in 
place of heavy oils worldwide 
 
• acceleration of interest appraisal 
and development of ukcs heavy oil 
 
• improvement of technology in well 
control and measurement 
 
• development cost comparable to

ukcs heavy oil fields tend to be relatively 
shallow have a relatively thick oil column 
with a large aquifer beneath and in  
a number of cases a substantial gas  
cap reservoir features often include 
favourable porosity and permeability 
features which support relatively high 
production flow rates per well most 
discovered heavy oil has relatively low 
sulphur content 
new technology
continuing technological advances in 
well control and measurement while 
drilling mwd have greatly assisted  
the longterm exploitation of heavy oil 
fields as well as reduced the number  
of dry holes
a key factor in the development of  
heavy oil fields was the introduction of 
horizontal well technology horizontal 
well completions permit minimal 
pressure reduction in the reservoir but 
critically maximise the distance between 
the oil and water contact the best 
position generally being near the top  
of the reservoir horizontal wells also 
increase the production rates as the 
length of the well in the producing 
section of a reservoir is much greater 
than that in a vertical well
significant advances in pump technology 
have probably provided the most 
important contribution to heavy oil 
production economics electrical and 
hydraulic submersible pumps are now 
achieving multiple year runlives in 
heavy oil production service without 
requiring maintenance workovers 
thereby step changing oil lifting costs 
economic viability
heavy oil extraction may require longer 
lead times than lighter crudes but it is no 
longer regarded as excessively complex 
or novel whilst more extensive appraisal 
work may be required in the process of 
developing feasible and economic field 
development plans the associated wells 
are typically shallow and inexpensive 
when compared to deeper light oil 
reservoirs 
the capital requirements for the actual 
field production development of heavy  
oil are similar to those for lighter crudes 
although the target depths of the 
reservoirs are lower the requirement  
for horizontal drilling increases cost  
the requirement for complex process 
equipment and extended well testing 
also adds to the scale of total costs 
marketing and transportation of heavy  
oil is for many projects similar to that  
of light oil although prices are lower 
typically 10 to 15 less than brent 
there is a ready market transportation 
methods in the north sea are typically 
the same as other types of oil being 
predominantly by pipeline or tanker
although the economics of heavy oil are 
somewhat tighter than conventional oil 
most projects are economically viable at 
us30bbl whilst the current high price 
of oil makes heavy oil more attractive oil 
prices remain quite volatile therefore 
the judicious use of forward market 
instruments can mitigate oil price related 
risks and underpin profitable operations 
to a considerable extent
in the final analysis with the correct 
technology and careful planning the 
production of heavy oil can be very 
profitable nautical has access to its  
own specialist heavy oil processing 
equipment as well as access to heavy  
oil marketing and endusers through its 
relationship with the masefield group

chief executive’s
review
this first period has been particularly exciting with strong 
progress made by implementing our stated business strategy 
of acquiring appraising and developing discovered heavy  
oil resources
nautical is developing rapidly having 
assembled a valuable and broad base  
of real assets through enacting a sound 
business plan shaped for our specialist 
niche of heavy oil nautical petroleum  
is the only uk listed company offering 
direct exposure to heavy oil development 
in the ukcs with a mixture of nearterm 
development appraisal and exploration 
the company’s portfolio is balanced with 
significant resource upside
this first period has been particularly 
exciting with strong progress made  
by implementing our stated business 
strategy of acquiring appraising  
and developing discovered heavy oil 
resources and securing high impact 
exploration acreage with limited work 
commitments
key highlights of the period include the 
admission to aim the agreed acquisition 
of additional acreage both in the north  
sea and south west france and the 
successful multilicence farmout 
agreement with sk corporation of  
south korea
review of activities
creating a longterm business
the company aims to retain significant 
stakes and operate its licences to this 
end nautical was approved by the dti as 
an exploration operator in october 2005 
and fulfilled all obligations on licence 
p1077 block 92b entering the second 
two year term
licence p1077 was one of the company’s 
two licences licence p1203 being the 
other at the time that the company was 
admitted to aim since then its portfolio 
has been increased with the acquisition 
of alba resources mariner discovery 
and two exploration licences the award 
of two licences three blocks as operator 
in the 23rd seaward licensing round 
and the farmin awaiting french 
governmant approval to earn a 22 
interest in the st laurent permit in south 
west france which marks the 
company’s first foothold on mainland 
europe agreements were signed  
to acquire a further two blocks from 
engen resources ltd in the post  
balance sheet period
nautical now has interests in 10 blocks 
five discoveries in the ukcs and one 
licence in france with nautical operating 
eight blocks the company’s main aim 
during the period was to more tightly 
define the hydrocarbon volumes in place 
in both discoveries and exploration 
prospects this has been achieved by  
the careful interpretation of reprocessed 
seismic data integrated with the 
petrophysical studies resulting in the 
reduction of risk nautical is further 
mitigating risk by farming down its 
interest in four blocks to a respected 
third party celtic oil limited a wholly 
owned subsidiary of sk corporation  
as well as by accelerating its drilling 
activity thereby furthering the 
company’s exploration and appraisal 
ambitions
farmout agreement
spreading the risk
it is nautical’s aim to mitigate exploration 
and appraisal risk by farming out the 
drilling of mature prospects and in  
june 2006 it successfully concluded a 
comprehensive multilicence farmout 
agreement with sk corporation asia’s 
leading energy and petrochemical 
company the agreements cover a 
selection of heavy oil prospects within 
the company’s portfolio as well as 
detailing where celtic oil ltd will  
carry part of nautical’s exploration 
expenditures on a twoforone basis for 
the proposed work programme the wells 
are to be drilled between 2007 and 2008 
as part of nautical’s commitment to its 
licensing terms with the dti
the farmout invitation process followed 
comprehensive technical preparation by 
nautical and was conducted over a two 
our strategy
nautical petroleum plc intends to 
become a significant producer of heavy 
oil initially in the ukcs and in europe 
• secure further heavy oil discoveries 
in ukcs and eu through 
acquisitions farmins and licensing 
rounds
• achieve near term production on 
current assets 
• enhance crude value and mitigate 
risk through our relationships
• acquire heavy oil exploration blocks 
with lowmoderate commitments
• farmout to mitigate portfolio risk
resulting in enhanced  
shareholder value 07 report and accounts 2006 nautical petroleum plc
month period the programme saw more 
than 10 companies assess the potential 
of nautical’s assets on offer and 
represents independent confirmation  
of growing industry interest in north  
sea heavy oil opportunities effectively 
endorsing the business focus and 
strategy of the company our strategy of 
thorough technical preparation provided 
a sound basis for the evaluation of the 
opportunities in our asset base and this 
transaction supports an acceleration and 
expansion of our immediate work 
programme 
technology
nautical owns specialist process 
equipment suitable for use in the testing 
of heavy oils down to 10 api the 
equipment can handle up to 40000 
barrels per day bopd of liquid 
production of which 25000bopd can  
be oil this technology could be used  
on the testing of the 92b discovery as 
well as future nautical development 
programmes and when not in use there 
are opportunities to hire the equipment 
out to third parties ownership of this 
equipment provides commercial leverage 
and a competitive advantage 
oil portfolio audit
rps energy audited our oil portfolio  
held at 30th june 2006 reserves and 
resources quoted in this report refer to 
the figures verified by this audit all 
reserves are proven plus probable and all 
contingent resources and prospective 
resources are best estimates
postyear end
north sea block acquisitions  
resource additions in our core area
in july 2006 nautical entered into an 
agreement to acquire a 985 operated 
interest in the bluebeard block 912b 
licence p1079 and skipper block 921 
licence p1080 discoveries on the east 
shetland platform from engen resources 
ltd for a minimum of us265m in shares
this transaction secured significant 
reserves adjacent to our current portfolio 
the bluebeard discovery is located 
directly east of the mariner discovery 
and is in close proximity to oil 
transportation facilities capable of 
accepting additional throughput three 
wells have been drilled 9123 in 1975 
912b6 1985 and 912b4 1982 the 
first two wells flowing 144 and 728bopd 
respectively from the maureen 
formation this is the same reservoir as 
mariner but the oil with an 18 to 19api 
and a viscosity of less than 20cp is of 
better quality a further shallower 
reservoir the eocene mousa formation 
was oil bearing in 912–3 but the oil is 
more viscous and with a lower api 10 
than the deeper formation a competent 
persons report commissioned by engen 
assigns best estimate contingent 
resources of 169 million barrels of oil 
mmbo 166mmbo net to nautical to  
the bluebeard discovery
the skipper discovery is located 
immediately east of the selkie and kelpie 
prospects block 825a and was tested 
by well 9212 in 1990 encountering a 
16 metre oil column in excellent quality 
paleocene dornoch formation sands an 
fdp based on best estimate contingent 
resources of 331mmbo 326mmbo net  
to nautical and 2d seismic data 
interpretation was submitted to the dti
both blocks are subject to a farmin by  
a third party which if concluded would 
reduce nautical’s financial exposure  
on an appraisal well on bluebeard to a 
minimal level
market overview
nautical expects international oil  
prices to remain relatively high for  
the foreseeable future additionally  
a narrowing of the heavy crude oil 
discounts is also anticipated as demand 
rises and refineries are upgraded to 
process more complex crudes 
unfortunately buoyancy in the 
commodity price has been accompanied 
by cost escalation for services 
exacerbated by tightening availability 
particularly with respect to drilling rigs 
the company has acquired site surveys 
over two structures so that it is drill
ready and can take advantage of rig slots 
when they emerge the challenge in the 
coming year and beyond will be to 
manage cost escalation driven by 
industrywide shortages of equipment 
and personnel the increased call on 
resources in the upstream sector and 
attendant cost pressures present a 
challenge to the sector but should not 
prejudice the viability of the company’s 
business model and furthermore are 
significantly mitigated by our strategy
the future
nautical will continue to add shareholder 
value through effective management 
fully evaluating our assets and further 
expanding our portfolio by diligent 
acquisition and licence round awards
nautical continues to look forward to  
first revenues from our highquality 
discoveries both in the ukcs and 
onshore europe with our focus shifting  
to the development and management  
of an extensive drilling programme 
across our asset portfolio

located on the east shetland platform 
west of the viking graben block 911a 
contains the mariner discovery drilled  
in 1981 since then data from several 3d 
surveys have been acquired nine vertical 
wells and six highangle horizontal wells 
have been drilled the vertical wells 
produced 1000 to 1595bopd
in 1997 an extended well test ewt 
produced 662000 barrels of oil over 63 
days at a maximum rate of 14991bopd 
145 api the main reservoir is the 
tertiary paleocene maureen sandstone 
which has a gross thickness of up to 
122 metres and excellent reservoir 
characteristics the trap is both 
structural and stratigraphic with the 
reservoir pinching out to the west  
north and south a shallower reservoir 
heimdal sandstone member could 
recover gross contingent resources  
of 51mmbo 14mmbo net to nautical  
this reservoir has flowed up to 1800bopd 
on a vertical test
nautical is an active partner in this 
highly appraised discovery and is 
encouraging early development the 
group led by chevron reprocessed the 
merged 3d seismic data resulting in 
greater clarity to the imaging of the 
maureen reservoir a key factor in this 
predevelopment stage mapping of the 
seismic data has reduced the range of 
hydrocarbon volumes as well as the 
stratigraphic and structural uncertainty
progress towards the submission of the 
field development plan continues with 
the dynamic modelling of the maureen 
reservoir estimating 82mmbo proven

development plan approval nautical will 
either be required to pay £1 to retain this 
interest or will be reimbursed past costs

the equity capital raisings in july 2005 
and january 2006 as well as the farmout 
agreement reached with sk corporation 
of south korea have assured the financial 
resources required for a comprehensive 
exploration and appraisal programme  
on several of the group’s assets with  
the aim of accelerating the production 
phase at the same time the agreed 
farmout with sk corporation helps to 
mitigate some of the exploration risks  
for the group
results for the period
the group recorded a loss of £73m  
for the period ended 30 june 2006 which 
included a charge of £51m for the write
off of goodwill arising from the adoption 
of reverse acquisition accounting for 
consolidation purposes the general  
and administrative expenses amounted 
to £19m including a charge for the  
share options and the exploration 
expenditure writtenoff in the period 
amounted to £07m
loss per share was 089p
cash flow and capital expenditure
as a result of the two equity capital 
raisings in the period totalling £18m  
the group closed the period with a 
healthy cash balance of £123m this  
is after covering the cash consideration  
of the alba resources holdings  
group acquisition of £34m the 
capitalised exploration expenditure of 
£27m and the cash portion of the general 
and administrative expenditure 
mentioned above
other capital expenditure amounted to 
£01m for the period most of which was 
on the extended well test equipment 
balance sheet and financing
the balance sheet was considerably 
strengthened by the £18m of equity 
finance raised during the period and  
the acquisition of the alba resources 
holdings group shareholders’ funds 
amounted to £532m as at 30 june 2006
the group is well funded for its 
forthcoming exploration and appraisal 
programme in 2007 having cash 
resources of £123m as at 30 june 2006 
and the provision of the agreed farmout 
with sk corporation
financial instruments
the group’s financial instruments 
comprise cash and liquid resources and 
various other items such as trade debtors 
and creditors which arise directly from 
its operations it is and has been 
throughout the period under review 
nautical’s policy that there is no trading 
in financial instruments
the main risks currently arising from  
the group’s financial instruments are 
foreign exchange risk interest risk and 
liquidity risk the board reviews and 
establishes policies for managing each  
of these risks and monitors them on a 
regular basis
no derivatives or hedges were entered 
into during the period under review
transition to international financial 
reporting standards
the group has commenced the transition 
to international financial reporting 
standards ifrs since 30 june 2006  
and plans to issue the 31 december 2006 
interim and the 30 june 2007 final 
financial statements in accordance with 
ifrs this will involve restating prior 
periods’ results and updating the group’s 
accounting policies as necessary
the future
nautical petroleum strategy is to focus on 
organic growth opportunities in our core 
markets whilst making complementary 
“bolton” acquisitions the financial 
performance of the group during the last 
18 months reflects the actions to complete 
the transitional phase into a focused 
heavy oil production and development 
company with a clear objective secured 
assets and the resources to move forward 
we continue to place cash management 
at the forefront of our financial strategy 
and we are focused on minimising the 
group’s working capital requirements 
we intend to continue with niche 
acquisitions where they supplement

goodwill
goodwill arising on consolidation representing the excess of the fair value of the consideration given over the fair values of the 
identifiable net assets acquired is capitalised and amortised using an appropriate method with regard to the type of assets 
acquired over its estimated useful economic life it is reviewed for impairment at the end of the first full financial year following 
the acquisition and in other periods if events or changes in circumstances indicate that the carrying value may not be 
recoverable
the goodwill arising on the reverse acquisition of bullion resources plc has been written off in the first financial period for the 
reasons explained in note 2
exploration appraisal and development expenditure
the company accounts for exploration and development costs on “the successful efforts” basis whereby all licence acquisition 
exploration drilling and appraisal costs are initially capitalised as intangible assets in cost centres by well field or exploration 
area as appropriate pending determination of commercial reserves these costs are then written off unless commercial reserves 
have been established or the determination process has not been completed following the establishment of commerciality the 
attributable costs are transferred to tangible fixed assets in a single field cost centre other prelicence and exploration costs are 
initially capitalised and then written off in the period incurred all development costs are capitalised on a fieldbyfield basis
commercial reserves
commercial reserves are proven and probable oil and gas reserves as defined in the uk sorp
depreciation of tangible fixed assets

off the costs less estimated residual values of each asset over its expected useful life on a straight line basis as follows
extended well test equipment      20 years
computers fixtures and fittings      3 years
impairment

circumstance indicate that the carrying amount of the fixed asset or intangible asset may not be recoverable to the extent that 
the carrying amount exceeds the recoverable amount being the higher of the net realisable value and the value in use the fixed 
asset or intangible asset is written down to its recoverable amount
exploration and appraisal costs capitalised pending determination of whether or not they have found commercial reserves are 
specifically exempt from the detailed rules for assessing impairment set out in frs 11

1 accounting policies continued

arrangements do not constitute entities in their own right the financial statements reflect the relevant proportions of costs 
revenues assets and liabilities applicable to the group
current tax

or paid to the taxation authorities the tax rates and tax laws used to compute the amount are those that are enacted or 
substantially enacted by the balance sheet date
deferred tax
deferred tax is recognised in respect of all timing differences that have originated but not reversed at the balance sheet date 
where transactions or events have occurred at that date will result in an obligation to pay more or a right to pay less or receive 
more tax
pension costs
the company contributes to a defined contribution scheme contributions are charged to the profit and loss account as they 
become payable
share option costs
the costs of share options are calculated as the difference between the exercise price and the price prevailing on the date of 
award where the share options are based on future performance criteria the cost is charged to the profit and loss account over 
the period from when the share options come into effect and the dates when they can be exercised where the share options are 
granted for past performance the cost is charged to the profit and loss account on the date the share options come into effect

2 reverse acquisition accounting
on 1 april 2005 the company became the legal parent company of nautical holdings limited in a shareforshare transaction  
and changed its name from bullion resources plc to nautical petroleum plc due to the relative size of the companies nautical 
holdings limited shareholders became the majority holders of the enlarged share capital further the company’s continuing 
operations and executive management became those of nautical holdings limited accordingly the substance of the 
combination was that nautical holdings limited acquired nautical petroleum plc in a reverse acquisition
under the requirements of the companies act 1985 it would normally be necessary for the company’s consolidated accounts to 
follow the legal form of the business combination in that case the precombination results would be those of nautical petroleum 
plc and nautical holdings limited would be included only in relation to its performance from 1 april 2005 however this would 
portray the combination as the acquisition of nautical holdings limited by nautical petroleum plc and would in the opinion of 
the directors fail to give a true and fair view of the substance of the business combination accordingly the directors have 
adopted reverse acquisition accounting as the basis of consolidation in order to give a true and fair view
in invoking the true and fair override the directors note that reverse acquisition accounting is endorsed under ifrs 3 and that the 
urgent issues task force uitf of the uk’s accounting standards board has considered the subject and concluded that there 
are instances where it is right and proper to invoke the true and fair override in such a way uitf information sheet 17
by adopting reverse acquisition accounting for consolidation purposes goodwill on acquisition arises which has been fully 
written off to the profit and loss account because bullion resources plc had no continuing business and therefore no intrinsic 
value the goodwill is £5077k as set out in note 22
given that nautical holdings limited was incorporated on 18 august 2004 the comparative figures for the prior year under 
reverse acquisition accounting are for the nautical holdings group for the period from this date to 31 december 2004 the 
company information presented is for the legal parent nautical petroleum plc 36 nautical petroleum plc report and accounts 2006

nautical petroleum plc report and accounts 2006


Summary:
 06 nautical petroleum plc report and accounts 2006
chief executive’s
review
this first period has been particularly exciting with strong 
progress made by implementing our stated business strategy 
of acquiring appraising and developing discovered heavy  
oil resources
nautical is developing rapidly having 
assembled a valuable and broad base  
of real assets through enacting a sound 
business plan shaped for our specialist 
niche of heavy oil nautical petroleum  
is the only uk listed company offering 
direct exposure to heavy oil development 
in the ukcs with a mixture of nearterm 
development appraisal and exploration 
the company’s portfolio is balanced with 
significant resource upside
this first period has been particularly 
exciting with strong progress made  
by implementing our stated business 
strategy of acquiring appraising  
and developing discovered heavy oil 
resources and securing high impact 
exploration acreage with limited work 
commitments
key highlights of the period include the 
admission to aim the agreed acquisition 
of additional acreage both in the north  
sea and south west france and the 
successful multilicence farmout 
agreement with sk corporation of  
south korea
review of activities
creating a longterm business
the company aims to retain significant 
stakes and operate its licences to this 
end nautical was approved by the dti as 
an exploration operator in october 2005 
and fulfilled all obligations on licence 
p1077 block 92b entering the second 
two year term
licence p1077 was one of the company’s 
two licences licence p1203 being the 
other at the time that the company was 
admitted to aim since then its portfolio 
has been increased with the acquisition 
of alba resources mariner discovery 
and two exploration licences the award 
of two licences three blocks as operator 
in the 23rd seaward licensing round 
and the farmin awaiting french 
governmant approval to earn a 22 
interest in the st laurent permit in south 
west france which marks the 
company’s first foothold on mainland 
europe agreements were signed  
to acquire a further two blocks from 
engen resources ltd in the post  
balance sheet period
nautical now has interests in 10 blocks 
five discoveries in the ukcs and one 
licence in france with nautical operating 
eight blocks the company’s main aim 
during the period was to more tightly 
define the hydrocarbon volumes in place 
in both discoveries and exploration 
prospects this has been achieved by  
the careful interpretation of reprocessed 
seismic data integrated with the 
petrophysical studies resulting in the 
reduction of risk nautical is further 
mitigating risk by farming down its 
interest in four blocks to a respected 
third party celtic oil limited a wholly 
owned subsidiary of sk corporation  
as well as by accelerating its drilling 
activity thereby furthering the 
company’s exploration and appraisal 
ambitions
farmout agreement
spreading the risk
it is nautical’s aim to mitigate exploration 
and appraisal risk by farming out the 
drilling of mature prospects and in  
june 2006 it successfully concluded a 
comprehensive multilicence farmout 
agreement with sk corporation asia’s 
leading energy and petrochemical 
company the agreements cover a 
selection of heavy oil prospects within 
the company’s portfolio as well as 
detailing where celtic oil ltd will  
carry part of nautical’s exploration 
expenditures on a twoforone basis for 
the proposed work programme the wells 
are to be drilled between 2007 and 2008 
as part of nautical’s commitment to its 
licensing terms with the dti
the farmout invitation process followed 
comprehensive technical preparation by 
nautical and was conducted over a two 
our strategy
nautical petroleum plc intends to 
become a significant producer of heavy 
oil initially in the ukcs and in europe 
• secure further heavy oil discoveries 
in ukcs and eu through 
acquisitions farmins and licensing 
rounds
• achieve near term production on 
current assets 
• enhance crude value and mitigate 
risk through our relationships
• acquire heavy oil exploration blocks 
with lowmoderate commitments
• farmout to mitigate portfolio risk
resulting in enhanced  
shareholder value 07 report and accounts 2006 nautical petroleum plc
month period the programme saw more 
than 10 companies assess the potential 
of nautical’s assets on offer and 
represents independent confirmation  
of growing industry interest in north  
sea heavy oil opportunities effectively 
endorsing the business focus and 
strategy of the company our strategy of 
thorough technical preparation provided 
a sound basis for the evaluation of the 
opportunities in our asset base and this 
transaction supports an acceleration and 
expansion of our immediate work 
programme 
technology
nautical owns specialist process 
equipment suitable for use in the testing 
of heavy oils down to 10 api the 
equipment can handle up to 40000 
barrels per day bopd of liquid 
production of which 25000bopd can  
be oil this technology could be used  
on the testing of the 92b discovery as 
well as future nautical development 
programmes and when not in use there 
are opportunities to hire the equipment 
out to third parties ownership of this 
equipment provides commercial leverage 
and a competitive advantage 
oil portfolio audit
rps energy audited our oil portfolio  
held at 30th june 2006 reserves and 
resources quoted in this report refer to 
the figures verified by this audit all 
reserves are proven plus probable and all 
contingent resources and prospective 
resources are best estimates
postyear end
north sea block acquisitions  
resource additions in our core area
in july 2006 nautical entered into an 
agreement to acquire a 985 operated 
interest in the bluebeard block 912b 
licence p1079 and skipper block 921 
licence p1080 discoveries on the east 
shetland platform from engen resources 
ltd for a minimum of us265m in shares
this transaction secured significant 
reserves adjacent to our current portfolio 
the bluebeard discovery is located 
directly east of the mariner discovery 
and is in close proximity to oil 
transportation facilities capable of 
accepting additional throughput three 
wells have been drilled 9123 in 1975 
912b6 1985 and 912b4 1982 the 
first two wells flowing 144 and 728bopd 
respectively from the maureen 
formation this is the same reservoir as 
mariner but the oil with an 18 to 19api 
and a viscosity of less than 20cp is of 
better quality a further shallower 
reservoir the eocene mousa formation 
was oil bearing in 912–3 but the oil is 
more viscous and with a lower api 10 
than the deeper formation a competent 
persons report commissioned by engen 
assigns best estimate contingent 
resources of 169 million barrels of oil 
mmbo 166mmbo net to nautical to  
the bluebeard discovery
the skipper discovery is located 
immediately east of the selkie and kelpie 
prospects block 825a and was tested 
by well 9212 in 1990 encountering a 
16 metre oil column in excellent quality 
paleocene dornoch formation sands an 
fdp based on best estimate contingent 
resources of 331mmbo 326mmbo net  
to nautical and 2d seismic data 
interpretation was submitted to the dti
both blocks are subject to a farmin by  
a third party which if concluded would 
reduce nautical’s financial exposure  
on an appraisal well on bluebeard to a 
minimal level
market overview
nautical expects international oil  
prices to remain relatively high for  
the foreseeable future additionally  
a narrowing of the heavy crude oil 
discounts is also anticipated as demand 
rises and refineries are upgraded to 
process more complex crudes 
unfortunately buoyancy in the 
commodity price has been accompanied 
by cost escalation for services 
exacerbated by tightening availability 
particularly with respect to drilling rigs 
the company has acquired site surveys 
over two structures so that it is drill
ready and can take advantage of rig slots 
when they emerge the challenge in the 
coming year and beyond will be to 
manage cost escalation driven by 
industrywide shortages of equipment 
and personnel the increased call on 
resources in the upstream sector and 
attendant cost pressures present a 
challenge to the sector but should not 
prejudice the viability of the company’s 
business model and furthermore are 
significantly mitigated by our strategy
the future
nautical will continue to add shareholder 
value through effective management 
fully evaluating our assets and further 
expanding our portfolio by diligent 
acquisition and licence round awards
nautical continues to look forward to  
first revenues from our highquality 
discoveries both in the ukcs and 
onshore europe with our focus shifting  
to the development and management  
of an extensive drilling programme 
across our asset portfolio
