Thailand: Bua Ban fault block has oil in three zones

By OGJ editors
HOUSTON, Apr. 7
– Coastal Energy Co., Houston, said it encountered oil in three zones in the Bua Ban North A-04 well in the western Songkhla basin in Thailand.

Coastal drilled the A-04 well to 6,417 feet true vertical depth to test Miocene and Upper Oligocene targets in an upthrown block west of the discoveries in the A-01 well. A-04 cut 22 ft of net pay with 29% average porosity in Miocene. The company estimated 6 million bbl of oil in place in the fault block separate from the A-01 discovery well.

A-04 also cut 11 ft of net sand with shows in a deeper Miocene section with 22% average porosity and 10 ft of net sand with shows in Upper Oligocene with 25% porosity. These two zones were not able to be tested due to the high angle of the well, and testing is to begin in May. Other Bua Ban North wells have not found the deeper Miocene zone.

The company plans to target the recently discovered zones with horizontal wells to maximize production. The original Miocene vertical test well at Bua Ban continues to produce more than 200 b/d of oil with no water. Coastal has spud the A-03 well south of A-01 and A-04.
