... is in the strongest position in its history

  • Clear path to 100,000 boepd

from existing projects

  • >1.5 billion of prospective

resources in the exploration portfolio

  • Fully funded programme with

strong and rising cash flows

  • Proven capability to deliver

Acquisition of 60% of Rockhopper’s licence interests in the Falkland Islands

  • Premier to farm-in for 60% of Rockhopper’s interests in

the Falklands, including the Sea Lion development – Progresses strategy of growth through investment in high quality projects – Leverages strong operatorship and FPSO development capabilities – Ongoing exploration opportunities in the North Falklands basin – Adds approximately 200 mmbbls of net discovered 2C resources at a low upfront cost, together with net risked prospective resources of 175 mmboe – Significantly extends Premier’s production growth beyond current development projects & is an excellent fit with strongly rising cash flows

  • Initial payment of $231 million plus an exploration carry
  • f up to $48 million and, subject to FDP approval, a

development carry of $722 million

  • Fully funded from a combination of existing cash

resources, facilities and cash flow from operations; commitment to fund dividend unchanged

Operations highlights

  • Chim Sáo and Gajah Baru onstream

– Deliverability exceeding expectations

  • Realising further value from producing assets
  • Continued progress on the development

portfolio: – Huntington and Rochelle progressing – Solan FDP approved by DECC – Development studies for Catcher well-advanced – Partner sanction of Pelikan, Naga & Dua

  • On track to reach 75,000 boepd run rate by

year end 2012, once Huntington and Rochelle

  • nstream
  • Anticipate reaching 100,000 boepd when

Catcher comes onstream in 2015

Natuna ‘A’ 2015

Block A – strong production performance

Anoa & GSA1

  • Producing at current maximum capacity

– 170-180 BBtud

  • Phase 4 expansion project underway

– Raising capacity to 200 BBtud

  • Pelikan will add 70 BBtud of capacity

Gajah Baru & GSA2/3/4

  • Currently producing at 60-90 BBtud
  • DCQ increases from 50 to 90 BBtud at end Q1

– 200 BBtud well deliverability

  • Indonesia will take an additional 40 BBtud when the

domestic swap agreement is signed Outlook

  • Series of new field developments will maintain rates
  • Exploration is adding additional reserves

Singapore Gas Market – sales are increasing

Singapore demand for gas will increase

  • Existing pipeline supplies are naturally declining
  • LNG supplies must commence and increase
  • But supply diversity will be maintained, and be

underpinned by 90% Take or Pay contracts

  • GSA1 demand expected to remain between DCQ

and Max Rate (341-392 BBtud) Premier’s GSA1 market share is increasing

  • Block A contractual market share of GSA1 is 37%

– 2012 1H Block A actual share of deliveries was 45% – Block A share of remaining reserves dedicated to GSA1 has increased to 59% – Other GSA 1 suppliers are expected to drop to 150-100 BBtud in 2015-2016

  • GSA 1 market available to Block A could increase

to 200-250 BBtud in 2015-2016

Chim Sáo – delivered and ramping up

  • First oil achieved, safely and on budget, in October

2011

  • Post- commissioning facilities issues largely

resolved – Average production for 1H 2012 was 26 kboepd

  • Currently producing around 30,000 bopd of oil and

5,000 boepd of gas – Rates limited due to water injection delays – 9 production wells could reach 40,000 bopd – Vessel capacity is 50,000 bopd

  • Supplementary drilling programme, which was

initiated to develop additional reservoirs, completed – Two wells being tied into Chim Sao facility and expected onstream 2H 2012 – Jack up rig moved to drill the Chim Sao North West appraisal well, which has now spudded

  • MDS5/6 reserves have increased by 10 mmbo

Chim Sáo – uncovering upside potential

Chim Sáo North West

  • Chim Sáo North West discovered in August 2011
  • Additional gross resource estimate 13 to 20 mmbo
  • Near vertical appraisal well spudded July 2012
  • Development will be via existing facilities

Additional Reservoirs

  • Further reserves potential is being

found in reservoirs other than MDS5/6 Tie-in of Dua

  • Government of Vietnam approved

ODP in December 2011

  • Project sanctioned by Premier and

Santos in April 2012

  • Long lead items being purchased

– Subsea wells and storage tank – Processing deck on a conventional jacket – Reserves estimate ~ 40 mmbo – Initial rate of 24,000 bopd – Capex of ~$850 mm with $30 mm/year opex

  • Premier will provide Chrysaor with a $50 million carry

and corporate loan for the balance of their equity – Loan recovered through Chrysaor’s cash flow

  • Solan will qualify for new “Small Fields Allowance”
  • DECC approval of Solan FDP received in April
  • Contracts for the topside facilities, steel jacket, heavy lift

installation & subsea tank fabrication have been awarded

  • Rig contract executed with Phase 1 development drilling

expected to commence in March 2013

  • First oil targeted for 4Q 2014

Catcher Area – selecting a development concept

  • Further 2011 drilling resulted in:

– STOIIP estimates of ~260-290 MMSTB – Reserves estimates of 80-130 MMSTB – Production rate of 50-70,000 bopd

  • EnCore acquisition has completed

– Premier in place as Operator with 50% equity

  • Conceptual Engineering studies completed

– Capex estimates range from $1.6bn for a leased FPSO to $2.8bn for a central fixed platform – JV concept selection process is underway

  • Development focused on eastern discoveries while the

Carnaby well will contribute as a future tie-back option

  • New “Small Fields Allowance” will apply to separate

accumulations on block

  • Announced ownership changes provide additional

financial certainty around the funding of the development

  • Targeting sanction by year-end with first oil in 2015
