Tullow Oil reports gas discovery at Bangora, Bangladesh

By OGJ editors

HOUSTON, Dec. 13 -- Tullow Oil PLC, Dublin, reported that its Bangora-1 natural gas discovery well on Block 9 at Bangora, Bangladesh, flowed during a production test at a combined rate of 120 MMscfd of gas from its three lowest zones. The well, drilled to 3,636 m, encountered several gas reservoirs at 2,580-3,285 m.

The lowermost E sand flowed gas at a top rate of 24.5 MMscfd. The D sand, 87 m thick, was tested in two separate zones: the Lower D at 41.2 MMscfd and the Upper D at 56.0 MMscfd.

Gas quality is high, Tullow said, with 99.13% combustible gases. Operator Tullow will test the shallower gas sands later, and the well will be suspended as a future production well.

Tullow will carry out a comprehensive appraisal program of the Bangora find and earlier Lalmai discovery on the same 40 km anticlinal structure, including additional seismic, drilling, and extended well testing.
