Baku, Azerbaijan, Aug. 11
By Elena Kosolapova - Trend: The Central Asian oil and gas company Roxi Petroleum made a further discovery at A5 well, located on the BNG Contract Area in Kazakhstan, the company reported on August 11.
Well A5, the first deep well on the BNG Contract Area, with a planned total depth of 4,700 meters is targeting principally the middle Carboniferous formation at 4,390 meters of the South Emba sub-basin.
"Roxi is pleased to announce a further core of 18 meters has been successfully taken between 4,347 and 4,365 meters, of which 5.62 meters was recovered. Initial examinations of this core confirmed it to be grey limestone, microcrystalline, dolomitic, fissured, vuggy and oil saturated over its full length," the company said.
This makes the aggregate thickness of the gross oil-bearing interval at least 33 meters.
As previously stated Roxi intends to continue core sampling until the oil shows disappear. The company is now working on taking a third core sample between depths of 4,365 and 4,383 meters. The flow rate of the well will be assessed once the core sampling is complete.
The BNG Contract Area is located in the west of Kazakhstan 40 kilometers southeast of Tengiz on the edge of the Mangistau Oblast, covering an area of 1,561 square kilometers of which 1,376 square kilometers has 3D seismic coverage acquired in 2009 and 2010.
Earlier oil and gas shows at well A5 were detected at a depth of 4,332 meters over the full 12 meters core taken.
Roxi has a 58.41 per cent interest in the BNG Contract Area.
Roxi Petroleum PLC is a Kazakhstan based oil and gas exploration and production company established in October 2006. Roxi's commercial rationale is to acquire and develop interests in oil and gas assets in Central Asia with a focus on Kazakhstan. Roxi's three principal assets are our interests in the BNG, Galaz and Munaily Contract Areas.
