HOUSTON -- Coastal Energy has updated information regarding its development and exploration drilling operations in the Gulf of Thailand.
The Bua Ban A-01, A-02, and A-05 wells now are complete with electric submersible pumps and tied into production facilities. Combined output from the wells is averaging 3,000 b/d of sweet, 30º API oil.
Bua Ban A-03 has reached a TVD of 8,650 ft (2,636 m), having been drilled off-structure to test the lower limits of the Lower Oligocene oil column. The well encountered 20 ft (6 m) of net pay in a Lower Oligocene section, 310 ft (94 m) beneath the previous lowest known oil point. It also encountered 24 ft (7.3 m) of net pay with 20% average porosity in the higher Miocene section at a TVD of around 3,400 ft (1,036 m).
Coastal is currently evaluating the play’s future prospectivity.
Elsewhere, the Benjarong A-01 and A-02 wells both flow tested at sub-commercial rates. Coastal now is examining the viability of fracture stimulation.
At the Songkhla A development, all four wells are performing in line with their modeled rates, with total production averaging 8,000–8,500 b/d.
“The initial test results at Bua Ban are encouraging,” says Randy Bartley, CEO. “Production from the A-05 well is higher than was anticipated in the original development plan. The new Miocene play seen in the A-03 well is exciting as it is the first time that productive Miocene sands have been encountered in Block G5/43. This discovery has significant potential for future appraisal and development. We continue to expect the current development at Bua Ban to bring further success and increases in production.”
