HOUSTON, Nov. 16 – Coastal Energy Co., Houston, said the A-09 appraisal well in Thailand’s Songkhla field extended lowest known oil in the Eocene by 105 ft.
Drilled to 8,109 ft true vertical depth, it cut 140 ft of net pay in the Lower Oligocene Wedge reservoir with 15% average porosity and cut 75 ft of net pay in the underlying Eocene reservoir seen in the A-07 well that initially tested 1,100 b/d of oil.
A-09 is 330 ft upstructure in Lower Oligocene from A-08, formerly the easternmost well on the structure. Pressures at A-09 approximate the original reservoir pressure at Songkhla Main, indicating no depletion of the Lower Oligocene Wedge from the Main reservoir. A-08 is the field’s best performing well to date.
The company has spudded Songkhla A-12, which will further appraise the Lower Oligocene Wedge.
