– Coastal Energy Co., Houston, has cased its Bua Ban North B-02 exploratory well in Thailand after it cut 62 ft of net pay in the Miocene objective with 26% average porosity.

The well also cut 150 ft of net sand with 19% average porosity in the Eocene interval. The Eocene sand zone was wet as it was not a target in this well and was drilled off structure.

The Eocene zone delivered the highest reservoir quality sands the company has seen to date in the Eocene interval, supporting its thesis of higher quality sands in the shallower Eocene and boding well for the planned drilling of shallower Eocene prospects to the northwest, Coastal said. TD is 6,513 ft true vertical depth.

Coastal set conductor pipe at the B-03 well, which is testing the Miocene in a separate fault block due east of B-02.
