The lowermost E Sand flowed gas at rates of up to 24.5 mmscfd. The D Sand (87m gross thickness) was tested in two separate tests: the Lower D Sand tested at a rate of 41.2 mmscfd and the Upper D Sand tested at 56.0 mmscfd. Gas quality is high, with 99.13% combustible gases. Shallower gas bearing sands will be tested at a later date.
The well will be suspended as a future production well. Tullow intends to carry out a comprehensive appraisal program over Bangora and the earlier Lalmai discovery, including further seismic, drilling and/or extended well testing.
Aidan Heavey, Chief Executive of Tullow commented:
"We are delighted with the better than expected test results from the Bangora-1 well which flowed at an aggregate rate of 120 mmscfd. Following on from the earlier discovery at Lalmai, we have now had gas discoveries at each end of a 40 km long anticlinal structure. We intend to carry out an accelerated appraisal program and deliver gas to the market at an early date."
