Coastal Touts Success at Bua Ban North Appraisal

Coastal Energy announced the successful results of the Bua Ban North B-04 appraisal well.

The Bua Ban North B-04 well was drilled to 6,000 feet TVD and encountered 64 feet of net pay in the Miocene objective with average porosity of 27%. The B-04 confirms the discovery made by the B-02 well, which encountered 62 feet of net pay in the Miocene with 26% porosity. The B-04 well is currently being cased and will then be suspended pending the arrival of production equipment. The Company plans to drill a water disposal well before mobilizing the rig to its next planned location.

Randy Bartley, Chief Executive Officer of Coastal Energy, commented, "We are pleased with the continued success in the Miocene trend at Bua Ban North B. Drilling is expected to be complete by mid-June and the Mobile Offshore Production Unit is scheduled to arrive in late June. A hydraulic unit will be used for completion operations and production testing is anticipated to begin in mid-July.

"The B-04 well further confirmed the Miocene trend at Bua Ban North B and the potential of the Miocene play across the Songkhla basin. Following Bua Ban North B, the rig will be mobilized to the Songkhla H prospect, which is in the middle of the basin between Songkhla A and Bua Ban. An exploration well will be drilled to test the Miocene and deeper zones at this location."
