Coastal Energy discovers oil at Benjarong offshore Thailand

Coastal Energy discovered oil pay zones with the Benjarong A-01 exploration well in the Gulf of Thailand

The Benjarong A-01 well was drilled to a total depth of 10,565 feet TVD (3,242 meters). The well appears to be an oil discovery and encountered 83.5 feet (25.5 meters) of apparent net oil pay in the Eocene primary reservoir, based on wireline log data. Porosity in the reservoir averages 11.9%. Additionally, the well encountered 16.5 feet (5 meters) of apparent net oil pay with 15.1% porosity in a shallower section of the Eocene reservoir. 

Coastal has spudded a second well, the Benjarong A-02, which will test Lower Oligocene and Eocene objectives in a structure separate from the Benjarong A-01 well. Following drilling of Benjarong A-02, Coastal will perform a flow test on Benjarong A-01. 

"The Benjarong A-01 well has characteristics similar to that of the original Benjarong-1 well which was drilled in 1996,” said Randy Bartley, CEO of Coastal Energy. “We have yet to determine the commerciality of the well at this porosity and will not be able to establish its productivity until a flow test is conducted. The flow test of the A-01 well is scheduled to begin once drilling of Benjarong A-02 is complete. In the event of an additional discovery at Benjarong A-02, it will be more cost effective to flow test both at the same time. Production from both wells would then be tied into a MOPU and produced in a manner similar to Songkhla A."
