Caspian Sunrise updates Kazakhstan operations

Caspian Sunrise PLC said an interval in its BNG asset in Western Kazakhstan appears to be larger than previously believed. The company issued an operations update saying a core sample from its Deep Well A8 on the Airshagyl structure showed traces of oil-bearing carbonate.

The company took an 18-m sample core at 4,440 m. The initial evaluation showed that the core contained oil-bearing carbonate for all but 2 m out of the 18 m.

In addition, a core was collected at 4,346-4,350 m, and a core was collected at 4,370-4,379 m. Preliminary analysis from the two core samples showed them to be porous with oil and natural gas.

Caspian Sunrise plans to drill additional 40 m before running a wireline analysis over the entire 110-m interval. The well will be cased to 4,500 m.
