  • Licence awarded 1993 – Shell (75%), Energy Africa (25%)

  • Energy Africa farm-out 15% to Texaco

  • Petroleum field declared 1997

  • Drilled four wells

  • Shell relinquished 2002 - ChevronTexaco (60% + operatorship), Energy Africa (40%)

What have we done differently

What have we done differently……

  • Initiated a “fresh” look at the broader development options

  • Recognized current window of opportunity in power market

  • Focused development on proven GIIP only : de-linked Phase 1 gas-to-power project from upside development opportunities

  • Established “open book” co-operative approach with downstream parties

Co-ordination, consultation, guidance, consensus (as per MOU/LOI)

Distinct but integrated elements of same project

Power demand growth in SADC

Courtesy

The Southern Africa Power Pool (SAPP) experiencing diminishing generation surplus capacity in the region caused by:

  • increasing power demand at a rate of three percent per year (1200MW) in the last six years

  • If no new generation project then in 2007, the SAPP will run out of generation surplus capacity.

  • There has been no significant investment in generation in the last 10-years, despite the rise in power demand.

    Current post phase 1 activities

    Current post-Phase 1 activities

    • Complete planning for drilling two wells in 2006 to confirm the upside potential in greater Kudu field area. Drilling timing dependent on:

      • Rig and materials availability

      • Partners (?)

    • High level techno-economic evaluation of the earlier work on the three post-Phase1 options and prepare work program for further investigation

    • Preparing to bring in new partners - probably during second half 2005


    In summary

    In summary:-

    • Phase1 - 800MW gas-to-power project progressing well with final investment decision expected early 2006

    • Post - Phase1 activities for evaluation of +/- 8 Tscf GIIP upside:

      • Preparation to drill two wells in 2006

      • Evaluating development options for three scenarios

        • Additional gas-to-power

        • LNG / GTL / CNG

        • Gas export to South Africa

    • Preparing to bring in additional partners during second half 2005
