Exploration and Production firm Caspian Oil & Gas reports that its rig is currently drilling ahead at 851m on its West Mailisu #2 well, after delays caused by mechanical failure.
The West Mailisu #2 well is on Caspian’s 100% owned West Mailisu licence in the Kyrgyz Republic, Central Asia.
Progress during the week was affected by ground conditions and mechanical problems with both of the rig’s mud pumps.
The pumps have now been repaired and are fully functional. Subject to ground conditions, the well will be cased at 1,700m prior to testing the primary and secondary targets, according to a company statement.
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 is targeting oil in Eocene age sands (Bed III) at about 1,740m and the carbonate Beds V & VII to 2,000m.
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 4.5 million barrels of oil calculated for the Eocene reservoirs.
