Tullow Oil Begins Production from Bangora-1 in Bangladesh

Tullow Oil has begun gas production from the Bangora-1 well in Bangladesh, a key part of the Group's Bangora/Lalmai appraisal program in Bangladesh.

Natural gas production from the Bangora-1 well in Block 9, Tullow's first production in Bangladesh, commenced on May 9, 2006 and has reached a gross stabilized flow rate of 50 mmscfd. This is a long-term production test and forms part of an appraisal program to test the size and connectivity of the reservoir discovered by the Bangora and Lalmai wells in 2004. The gas is being delivered into the Ashuganj-Bakhrabad pipeline and will supply much needed gas into the local market.

Production data from the Bangora well will be combined with new 3D seismic data, acquired in February this year, and the results from the appraisal wells. The Bangora-2 appraisal well commenced drilling on April 22 and is expected to take 40 days to reach the reservoir target. One further appraisal well is planned with two additional wells contingent on results.

In the event of positive results from this program, Tullow plans to declare commerciality and submit a full Field Development Plan to Petrobangla by the end of the year.
