Caspian Oil & Gas, an exploration firm based in  the Kyrgyz Republic, Central Asia reports that its rig was drilling ahead on its West Mailisu #2 well at 1,188m at 8.00 am Perth time, on the way to the primary target (sandstone Bed III) at 1,740 metres, according to a company statement.
The limestone Beds V and VII will then be tested prior to reaching the proposed well depth of approximately 2,000 metres.
The West Mailisu #2 well is on Caspian’s 100% owned West Mailisu licence in the Kyrgyz Republic.
The West Mailisu prospect lies adjacent to the Mailisu IV oil field, which has produced more than 42 million barrels of oil. West Mailisu #2 will target oil in Eocene age sands and carbonates (Beds III, V & VII).
The targeted feature is defined by a NW-SE trending reverse fault on the northern flank. Seismic sections across the structure indicate a robust closure.
The prospect has the potential to contain oil reserves of up to 9.7mmbbls, with mean potential reserves of 4.5mmbls calculated for the Eocene reservoirs. The well is being drilled by Caspian’s own rig to a depth of approximately 2,000m, testing the Eocene and upper Cretaceous sands.
