2011 Performance Summary

Solid year of operating performance 9% increase in NPAT to 202.5 million, reflecting strong production performance, higher oil prices. Excluding significant items, NPAT increased 65% to US$236.5 million PNG LNG construction now in full swing. Target of first LNG in 2014 remains unchanged and costs are under control Key strategies for growth being progressively delivered. Major drilling programme underway, will include:

Hides appraisal and development Highlands gas appraisal and exploration Gulf drilling Oil drilling – 2010/11 successes, with more to come

OSH ended 2011 in excellent financial position. Oil operations continue to generate good cash flows, corporate facility remains undrawn. Ample liquidity to fund PNG LNG and unprecedented growth programmes Two US cents per ordinary share, unfranked, final dividend, making four US cents per share for 2011. Final dividend payable on 10 April 2012

2011 Financial Performance

Full year revenue benefited from higher realised oil prices, partially

Increase in non-cash charges balanced by lower exploration expense (Wasuma and Korka wells expensed in 2010)

* 2011 core profit excludes impairment charge for Shakal (no tax benefit). 2010 core profit excludes one-off tax benefit associated with restatement of deferred tax balances associated with PNG LNG Project partially offset by impairment charge associated with various exploration permits ** See appendix A for reconciliation between NPAT and Core Profit

Gas Growth & Exploration

Key strategic priority for Oil Search is to grow gas business in PNG Pursuing a two pronged strategy:

PNG LNG Expansion Gulf Area LNG

In parallel:

Continuing near-field exploration Pursuing high-graded exploration outside PNG

PNG LNG Expansion

Drilling programme in PNG Highlands has commenced:

P’nyang South 1 (PRL 3) appraisal well spudded January 2012 Trapia (PRL 11) exploration well to follow P’nyang well Non-PNG LNG Project licences but high degree of common ownership, candidates for inclusion in expansion

Hides development drilling programme:

Scheduled to commence in mid 2012, GWC well planned for early in drilling sequence GWC well has potential to increase overall Hides resource volume significantly Drilling timing optimised with other construction logistics (Komo and HGCP)

Upside in Associated Gas fields:

Reserves and resources at 31 December 2011

No external reserves audit this year:

Field production performance consistent with predictions through 2011 Currently well advanced on building new reservoir models that will allow

  • ptimisation of production during gas depletion – will highlight additional
  • pportunities

Audit in 2012 will include updates for recent successes in development drilling and near field discoveries

2011 production of 6.7 mmboe led to:

Proven (1P) net remaining oil and gas reserves decrease from 336.8 mmboe to 330.1 mmboe Proven and Probable (2P) net remaining oil and gas reserves decrease from 559.3 mmboe to 552.6 mmboe

2012 Production Outlook

Underlying production from oil fields expected to remain strong, with 2012 production impacted by:

Significant contributions from successful 2011 wells and workovers Natural decline Three week shutdown for tie-in of Associated Gas facilities

Production guidance for 2012 of 6.2 – 6.7 mmboe, unchanged from 2011, with production out to first LNG broadly flat, subject to success of work programmes Robust workover and development drilling programme in 2012, coupled with continued focus on maturing near-field portfolio and appraising new pools identified following recent near-field success Rig strategy:

Following P’nyang drilling, Rig 103 to be mobilised back to PDL 2 Will provide optionality to pursue exploration and appraisal

  • pportunities without potential adverse impact on development

programme

Key 2012 Focus Areas

Maintain OSH’s industry-leading safety performance in very high activity environment across many sites Manage cost pressures of a strong PNG market Continue transformation of business towards reliable gas delivery:

Complete Associated Gas and Life Extension works Continue optimisation of gas depletion plan Align processes with gas supply obligations

Follow up near field successes in Agogo and Hedinia Support PNG LNG Project to ensure success as onshore pipeline construction moves through key oil operational areas

Strategy Delivery

Strategic Review in 2010/11 highlighted potential of present portfolio to continue to deliver top quartile TSR performance Major areas for delivery:-

PNG LNG Project in full construction, on track for 2014 LNG production LNG Growth initiatives focussed on resource definition:

Hides drilling in 2012/13 Highlands appraisal and exploration started Gulf potential confirmed, drilling preparations underway, partnering discussions commenced

PNG oil potential being accelerated, increased rig capacity, provides

  • ptionality

Oil exploration in MENA (Taza, Tunisia) also part of programme Active programmes to address operating risks:

Transparency in benefits Community engagement Health Foundation activities commenced

Financial strength with continued optimisation of structure and debt

4 8

slide-25
SLIDE 25

PNG Issues

PNG has experienced unprecedented political uncertainty over past 6 months:

No impact to operations Continued progress on all projects Security and safety of staff paramount

General Election in June 2012 with new government formed in August/September:

Anticipate no change to operating status but cautious and watchful Continue push for transparency and governance regarding benefits Enhance community engagement, including Health Foundation

Reaching peak of in-country activities, with continued but manageable stress on government systems, personnel and services availability

4 9

PNG Operating in Context

OSH likely to be PNG’s largest single investor in 2012, with over US$2bn to be spent on development, appraisal exploration and operations Significant vote of confidence in quality of assets and ability of Company to work with Government, bureaucrats and community, to manage operating and investment risks Comprehensive programme to manage these issues

slide-26
SLIDE 26

2012 Outlook

Peak activity year for PNG LNG Project delivery in 2012:

Construction at PNG LNG plant site, HGCP and Komo Completion of Associated Gas and life extension projects Focus on management of in country issues

Major drilling programme focused on gas expansion and resource underwriting. Potentially transformational for Oil Search

Hides evaluation P’nyang and Trapia wells Gulf area drilling

Active oil exploration programme:

Near field opportunities Kurdistan, Tunisia

Continued strong oil field production performance

5 1

2012 Outlook

Oil Search presently has unprecedented opportunity to underscore long term value growth from its portfolio of assets Remain confident that country risks and challenges can be managed through 2012. Continue to work closely with Government, bureaucracy, communities and partners to manage operating risk
