  1. Slide 1: Upstream and Talinga Gas Processing Plant

    Upstream and Talinga Gas Processing Plant Presented by Paul Zealand Chief Executive Officer, Upstream Origin Operational Review and Asset Visit 19-20 September, 2011

  2. Slide 2: Origin responsible for APLNG upstream program

    Origin is responsible for the upstream program for Australia Pacific LNG leveraging Origin’s 14 years’ CSG production experience … Origin and APLNG exploration and production permits in the Surat and Bowen basins … and addressing a high quality and diversified acreage position 2|

  3. Slide 3: APLNG Reserves and Upstream Production Costs

    APLNG has sufficient gas to underpin two trains, with 3P reserves of 14,742 PJ and an additional 10,050 PJ of contingent resources … APLNG Reserves and Resources Upstream Gas Production Costs Upstream Production Costs Train 1 Train 2 3C = 10,050 2C = 4,041 Lower unit Ramp and Tail cost gas 3P = 14,7

  4. Slide 4: APLNG holds acreage in both regions' sweet spots

    Australia Pacific LNG holds acreage in both of the regions’ “sweet spots” – Spring Gully/Fairview and the Undulla Nose • Australia Pacific LNG’s CSG position has the following characteristics: • Prime acreage in both Queensland CSG “sweet spots” of Spring Bowen Basin Gully/Fairview (Bowen Basin) and

  5. Slide 5: Production characteristics alongside best US regions

    The Spring Gully/Fairview and Undulla Nose regions have production characteristics ranking alongside the best producing regions in the US Field Net Coal Gas Content Permeability Australia Spring Gully/Fairview ** *** *** Walloons - Undulla Nose *** ** *** Walloons - Eastern *** * ** Walloons – North

  15. Slide 15: Design Evolution – Compressors

    Design Evolution – Compressors Spring Gully • Spring Gully has a 4 stage Talinga Spring Gully reciprocating compressor Talinga model: - Vibration - No flexibility to inlet conditions • Talinga has a combination of screw & reciprocating compressors: - No vibration - Large range of suction pressure fl

  16. Slide 16: Design Evolution – Water Treatment Plants

    Design Evolution – Water Treatment Plants Spring Gully • Spring Gully had the Talinga Spring Gully first Reverse Osmosis Talinga (RO) for CSG • Spring Gully completed the first creek discharge • Spring Gully water is also used for irrigation (Pongamia) • Talinga applied Lessons Learnt from Spring Gu

  17. Slide 17: Design Evolution – Ponds

    Design Evolution – Ponds Spring Gully Talinga Spring Gully Talinga • Spring Gully has had very little flexibility between ponds • Talinga has transfer and flexibility between most ponds • Spring Gully’s ponds are clay lined • Talinga’s ponds are HDP lined and are of a higher specification • Spring G

  18. Slide 18: Design Evolution – Wellheads

    Design Evolution – Wellheads Spring Gully Talinga Spring Gully • Spring Gully’s Talinga wellheads have: - No automation - 1 operator per 15 wells - Slow install (6 welds) - Hydra pack with oil and service requirements - Flexi hose which results in high maintenance requirements - Larger drill pads •

  19. Slide 19: Operations Capability

    Operations Capability • Production capacity was doubled in 14-15 months • Jobs were sourced through local labour • Manning and automation will be minimised with central control S Integrated Operations Centre, Brisbane • APLNG’s upstream operations have internal support capability for: – Engineering
