HOUSTON – Coastal Energy Co. reports successful drilling of its first horizontal development well at Bua Ban North in Thailand.

The Bua Ban North A-10 reached the Miocene reservoir on the western side of the field and encountered 1,185 ft (361 m) of net pay in the horizontal section. The lateral section was drilled at approximately 3,695 ft (1,126 m) TVD, which is 130 ft (40 m) above the known water level.

The well has been completed with a submersible pump and is ready to begin production when the MOPU installation is complete. The MODU is on site and installation is expected to be complete this week. 

“We are extremely pleased with the results of our first horizontal Miocene development well,” said Randy Bartley, president and CEO of Coastal Energy. “The A-10 well was drilled at a cost of less than $3 million, making horizontal development wells extremely effective for field development. Poor weather conditions and high seas delayed the installation of the MOPU until this week; however, we fully expect first production to be online by the end of November and for all Bua Ban North wells to be online and producing by mid-January.”
