Supply will remain tight until next decade
Only one project made it to FID in 2006 (Peru LNG). Two so far in 2007 (Skikda rebuild and Pluto)
New LNG supply will remain scarce until 2012-13 when greenfield projects come onstream but tightness could last longer as projects continue to face delays
In an environment of rising costs, greenfieldprojects are likely to negotiate price floors to justify the investment and secure financing

LNG prices have risen
Higher oil prices mean higher natural gas prices directionally, though gas prices are capped by competition from coal and nuclear at the burner tip, especially in the longer term.Construction costs have risen significantly The United States has entered the LNG market from virtually zero early in the decade, and is very likely going to become the second largest LNG importer next to Japan after 2010. Japan will continue to be the largest importer of LNG through 2020Indonesia, once the world’s largest LNG exporter, is heading for a decline of exports to nearly zero (except for Tangguh) due to a combination of resource problems and political pressure to divert resources to the domestic marketQatar holds most of the cards in the near term

High prices and high future demand?
FACTS view of the future is a HH price of US$7-9/mmbtu (real) long term, despite the current weak prices. However, prices may rise and fall with oil prices
Can the consumer pay US$7-9/mmbtu or higher ex-ship price? FACT believes the consumers in Japan, Korea, Taiwan, and the US have no choice. They are paying the high price for oil and they can afford the high price for gas, but do so reluctantly and with much resistance, particularly in the power sector
Some Asian countries are being asked to pay $8-12/mmbtu today to divert volumes from the West to the East
Can the Chinese and Indian consumers pay such prices? Can fertiliser producers pay such prices? The answer is highly uncertain. China and India are still not addicted to gas. They will find coal as the best buy. Some sectors can pay the high prices, but most cannot, particularly in the traditional state-owned power sector, except where gas replaces fuel oil or naphtha

PNG has competitive advantages
Quality and location of resource makes PNG very competitive in project line up for a 2013 – 2014 development timetable
Advantages of LNG from PNG Highlands:Substantial certified reserve base, sufficient to underwrite development
High liquids content improves economics
Clean gas, minimal impurities (CO2), no additional processing capex required
Onshore, with existing infrastructure base (Kutubu & liquids pipeline)
Environmental approvals well advanced
Excellent location to exploit Asian & US West Coast markets
Competitive labour costs relative to Australia
Favourable fiscal regime with strong Government support

LNG with ExxonMobilSummary
ExxonMobil Pre-FEED review progressing well - strong momentum
Participants in LNG pre-FEED are Hides/Angore/ Juha/ Kutubu/ Agogo/ Moran/Gobe Main JVs. OSH’s funding share is 36.6%. Interest post Government back-in/unitisation expected to be ~ 30%
Studies on technical aspects are ongoing and include LNG plant technology, configuration, site development and execution planning
Plant location being finalised
Negotiation of fiscal terms taking place with new PNG Government
Working towards agreement on Unitisation framework, Joint Development Agreement
Capex estimate of around US$10bn for 6.3 mtpa of capacity appears to be robust post Pluto, full bottom-up capex re-build underway pre-FEED
Timetable - target end 2007/early 2008 to enter FEED, up to 18 months to FID, mid-late 2013 for first deliveries F

Plant Size & Technology
Owners have considered the number and size of trains for the initial development
Currently certified resource supports an initial 6.3 mmpta LNG development
Owners elected to run dual pre-FEEDs in order to ensure appropriate technology selection
Pre-FEED work considered a single large train and dual smaller trains
Pre-FEED work also considered APCI technology and Cascade technology
Consideration has been given to risk and economics
Both technologies have proven track records
Work is being finalised

Oil Search in the MENA Region
OSH commenced programme of measured diversification into the Middle East/North African region in 2000Focus is on proven petroleum systems with:
Existing infrastructureLow finding & development costsLow well costs to complement PNG activityProduction & deliverability reliability, rapid first oil
OSH has established key strategic relationshipsSpecific National Oil Companies
Manage regional risk issuesSolid Opportunity flowJoint Operating arrangements
Strong cultural & political relationsExcellent databasesExisting long term relationships
Balance of Operated & Non-Operated areasLow cost entry

Why MENA?
Oil Search commenced programme of measured international diversification in 2000Middle East/North Africa (MENA) selected as focus areaRapidly built a material exploration portfolio in areas with proven petroleum systems Oil Search Production Sharing Agreements (PSAs) have attractive fiscal termsMENA has multiple near term drilling opportunities
Cost of typical onshore exploration well ~US$2–6 millionTarget sizes range from 5–100mmbblsLow capital and opex (typically <US$3/bbl and US$4/bbl respectively) with short payback periods
Complements PNG high cost, higher reward prospectsAccess to producing infrastructure in key basins Moderate/high security risk, but manageable

Portfolio Build in Progress
In past 12 months, OSH has initiated: 2 drilling rig campaigns in Yemen – onshore and offshore
4 rigs in Egypt – 2 drilling and 2 workover
Further production operations with our quality HSES program embedded
Achieved significant drilling performance improvements in each campaign
Resolved challenging cultural issues in new areasF

Portfolio Build in Progress
Technical challengesWe haven’t satisfied our exploration objectives
Score = 2 / 11 dry holes in Yemen
= 5 / 5 in Egypt, ERQ & 2nd’y targets in Egypt Area A
= 1 / 1 in Kurdistan
Higher risk end of the portfolio has been drilled in Yemen
So far frontier areas – B15, B35, Bina Bawi
Moderate risk basinal plays with 3D data – B43, B49, ERQ
Mature plays in structurally complex areas with limited ability to de-risk in Area A
Performance over a three year period will be the better judge, cannot achieve portfolio evaluation within calendar year

Portfolio Build in Progress
Portfolio is the envy of numerous competitorsBalance of higher/lower risk with high/lower reward
Operational skills are highly valued
Creates opportunities that OSH can capitalise on
Materiality still not there
Lacks a solid production element
Existing fields immaterial
Discovery & rapid development required
Acquisitions are still being reviewed
Further portfolio optimisation will continue
… lack of production is causing significant P&L pressures due negative impact of higher effective tax rate

• 3 successes (Ghard, Shahd and Rana 7-10mmbo each)
• 25+ additional prospects requiring 2+ rigs• <2 years remaining on license• Require continuously active drilling program
•Area A Expln• 2 Nubia test have come in deep & wet• Incremental oil in shallower horizons• Next expl wells in 4Q 2007, seismic interp’n ongoing
•Block6• 1 well & seismic obligation, well in 2009/10
Iraq (Kurdistan)•Medium-long term
positioning strategy•10% indirect
participation in Bina Bawi EPSA
• Bina Bawi drilling program completed
• Currently acquiring 250km 2D seismic data
•Evaluating other material opportunities
Tunisia•Building material exploration
position•2 blocks captured (1 operated) – to
be ratified 1Q 2008•Work program for each area
includes 2D seismic and 1 well
Yemen•Material exploration position, largest licence holder in country•5 operated & 2 non-operated area•1 of these is a development licence with production (Nabrajah)•Prodn ahead of forecast but upside remains tantalising•Exploration program – 2 successes (Nab 13 & 15) & 9 dry holes
to date (3xB49, 2xB15, 2xB35, 2xB43)• B49 – large residual columns• B15 – downgrade deeper areas• B43 - disappointing• B35 – proved working hydrocarbon system in block
• Initial results disappointing but strong shows in B49 & B35 and proven oil in B15 attest to active petroleum systems
•Subsurface de-risking required in 2008 including 3D seismic in B3, B7 and potentially B49 (dependent on extension)

MENA Specific Issues
MENA licences are Production Sharing Agreements compared to PNG licences which are Tax/Royalty
Except Egypt Area ‘A’ which is a Revenue Sharing Service Agreement
Production Sharing Agreements allow for Cost Recovery and Profit Sharing between the Contractor and the Government
Not subject to income taxCosts (exploration, development and operating) are recoverable against any future production subject to a cost recovery limitRemaining revenue after cost recovery is shared between the Contractor and the Government
For Oil Search, MENA costs (including unsuccessful exploration expenses) are not tax deductible against PNG income because of PNG tax law
However, costs are recoverable against any future productionExploration costs in Egypt Area ‘A’ are tax deductible (it is a Revenue Sharing Service Agreement)

2007 Update
Overall:
Underlying field performance is strong in all fields and reservoir management activities have been encouragingKutubu:
Decline has largely been mitigated by UDT7 and reservoir management activities. Performance of UDT7 remains encouraging
Moran:Impacted by NW Moran shut-in for 6 months and the poorer performance of M6 post-workover. Issues resolved in 2H and 2007 forecast to exceed 2006 by 5%
SE Mananda:Steady as a result of the improved field management
Gobe Main: Adversely affected by the gas compression shutdown during 4Q’06. Programme to convert to Upper Iagifu production is proceeding well
SE Gobe: Adversely affected by the gas compression shutdown. The Wedge area (SEG11) continuing to perform well
Hides:1Q production affected by Porgera JV turbine maintenanceOperations resumed during 2Q and demand is currently exceeding forecast

Operating cost sharing Reserves bookings and amortisation improvementsPossible tax rate improvements subject to negotiation with the StateIncremental pipeline tariffsIncremental condensateAbandonment cost deferral
Current thinking:Oil Search remains Operator of the oil fieldsOil fields have gas delivery obligations but retain flexibility to optimise oilGas offtake has positive impact on oil production and appears rate insensitive

Update on Financial Outlook for 2007
Oil Search remains unhedged, pure exposure to oil pricesSecond half field costs in PNG expected to be slightly higher than the first half, as advised at half yearSecond half corporate costs expected to be slightly higher, due to impact of strong Australian Dollar. Vigorous cost cutting taking place to ensure increase is not materialAmortisation rate expected to average around US$13.00/boeEffective tax rate estimated at 60-64%, very dependent on overall MENA result and impact of MENA exploration expense

Update on Capital Outlook for 2007/08
Cash at end September US$405.4m, no debt outstandingTargeted refinance of corporate (oil based) facility early in 2008. Refinance not expected to be impacted by sub-prime issues but sensible to defer refinance to new yearExploration and gas expenditure remains on target for upper end of US$230-240m half year guidance for 2007Development expenditure likely to be a little lower than US$100 million, rig/corporate expenditure close to US$65m target2008 exploration spend expected to remain around initial target of US$120m (ex gas), gas costs around US$60-70m, and development/production expenditure higher than US$125m half year outlook. These costs remain subject to detailed budget review and are indicative onlyF

Outlook for 2007
Production expected to be between 9.5 – 10.0 mmboe
Kutubu and Moran fields performing well, but no new development wells expected onstream in PNG in 2007. Focus in 2008
Rising production from MENA (Nabrajah, Area A, ERQ) and contribution from NW Moran will offset mature field declines
Expanded exploration programme to continue. 2H 2007 programme includes a number of high impact wells (Arakubi, NW Paua, ERQ)
Moving towards FEED decision on LNG – expect all major agreements to be in place/issues resolved by year end
