+++ History

• 1963 - South West Ampa Field discovered
• 1965 - Production started

+++ Geology

• The reservoirs are heterogeneous, stratified, fine to very fine grained deltaic sands with varying clay content, separated vertically by shales of great lateral extent. All sands silt-out northeastwards across the field. Typical permeabilities are 100-300 mDarcy (0.1-0.3 m2) at 25% porosity.
• There are some 625 reservoir units with STOIIP's ranging from 0.002 to 26.7 million m3, between 1,000 and 3,500 metres subsea.
• The Southwest Ampa oil is light (40° API, 825 kg/m3) with an initial low viscosity (0.35 cp), hence the mobility ratio is favourable. Initial solution gas/oil ratio (GOR) ranges from 70-2,300 m3/m3.
• In the deeper accumulations, most oil reservoirs have extensive gas caps with initially about one-half the hydrocarbon pore volume being gas filled.
