Tullow Oil Announces Gas Discovery at Bangora Well, Bangladesh



Tullow Oil, as Operator of Block 9, is pleased to announce the test results for
its gas discovery at Bangora, Bangladesh.  The Bangora-1 well was drilled to a
depth of 3,636m and encountered a number of gas bearing reservoirs between
2,580m and 3,285m.  Having completed the well, the three lowermost zones were
production tested, recording an aggregate flow rate in excess of 120 mmscfd.



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 programme 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
programme and deliver gas to the market at an early date.'
