Zhaikmunai has reported the results of tests at its future production well #20 situated in the northeastern part of the Chinarevskoye license area.
The well tested the Biski & Afoninski reservoir in the non-cemented casing in interval 4,806-5,409 m. On a 12-mm choke with a depression of 190 bars extrapolated, which is approximately 33 percent of the formation pressure, the well flowed 12.179 million cubic feet (MMcf) of natural gas and 2,016 barrels of condensate per day at a separator pressure of 25 bars from the Middle Devonian Biski & Afoninski carbonate formation. The formation was acid treated prior to test operations.
The multi-rate test of the Biski & Afoninski reservoir was carried out in the upper of two side-tracks drilled out of the existing 7" casing of well #20 at 4,800 meters. The well was deviated down to 5,095 m and drilled horizontally from 5,095 m to a final depth of 5,425 m.
Kai-Uwe Kessel, CEO of Zhaikmunai said, "This is the second horizontal well which has now been successfully tested at the Chinarevskoye field. The test results have met our expectations and are a further step forward towards Zhaikmunai's planned production ramp-up."
