16. Future Operations: Continue drilling ahead 8 1/2" hole with to the reservoir objectives in Nannyarra Sandstones. Prepare to run wireline logs.

17. Prospect Description: Good oil-prone source rocks are present in organic-rich marine shales nearby the Late Devonian Gneudna Formation. The Devonian section in the Quobba-1 well is predominantly shale so sealing of the reservoir in Lake MacLeod-1 are interpreted to be present. There were also good oil and gas shows throughout the Gneudna Formation in Quobba-1 demonstrating there are porous and permeable reservoirs in dolomites of the Gneudna Formation.

Structures drilled in the Gascoyne Sub Basin to date such as Quobba-1, Pendock-1D and Wandagee-1 were all formed during the Miocene which post dates primary hydrocarbon migration and are dry.

The Lake MacLeod structure is interpreted to have formed during the Devonian and pre date primary hydrocarbon migration from the Gneudna Formation source rocks which generated their hydrocarbons during the Late Carboniferous to Permian. It is important to note that none of these early aged structures have been drilled in the Gascoyne Sub basin, Carnarvon basin.

The large Lake MacLeod Prospect covers an area of 27,500 hectares (70,000 acres). Estimated potential recoverable reserves for the larger Lake MacLeod-1 Prospect if the structure is filled to its maximum spill point are in the order of 150 million barrels. Potential recoverable oil reserves within the Lake MacLeod structure in the EP 461 Permit are more conservatively calculated using a 5000 hectare closure at the Top Nannyarra Sandstone and are estimated to be in the order of 30 million barrels of oil.
