The company said that after an initial clean up period, the well produced gas at an estimated flow rate of 4 million standard cubic feet per day (mmscfd) along with some drilling fluids, however the gas flow decreased and was replaced with water.
The flowing water is believed to be formation water, flowing at an estimated rate of 4,300 bbl per day.
The well was then shut-in and then re-opened for a second flow period after which the well initially flowed water and then produced gas at an estimated flow rate of 1mmscfd, however again, the gas flow decreased and was replaced with water at an estimated rate of 750 bbl per day.
The company has planned to drill ahead through the remaining Cretaceous section for evaluating the Qamchuqa reservoir and then the deeper reservoirs in the Jurassic.
The well is expected to reach a depth of 3,660m during the fourth quarter of 2010.
The well has been drilled to an intermediate depth of 2,395m and open-hole wire-line log data acquired from 1,450m to 2,395m.
The analysis of the wire-line log data suggested potential hydrocarbon bearing zones and the company has completed open-hole drill stem tests (DST) over two prospective zones identified from the well data.
DST #1 was performed using inflatable straddle packers to selectively test an open-hole interval within the Cretaceous age Kometan formation.
DST #2 was performed with a casing packer set near the shoe of the 9 7/8" casing and an inflatable open-hole bridge plug set within the Cretaceous age Shiranish formation in order to test an open-hole interval of the Shiranish.
