Tullow Says Lalmai Well in Bangladesh has Gas Potential

The Lalmai-3 exploration well in Block 9, Bangladesh, was spudded on March 8, 2004, and reached its proposed total depth of 2800m on April 25, 2004. The wireline logs have identified potential gas-bearing sands in a number of zones between 2200m and 2800m, however it has not been possible to complete the logging program due to hole conditions. Subject to co-venturer approval, Tullow will shortly begin testing these potential gas zones, including production testing without a rig. This will allow the rig to be moved to Bangora, the third well in Tullow's three well exploration program for Block 9. Production test results for Lalmai-3 are expected in three to four weeks time.

Brian O'Cathain, Tullow's General Manager International commented:

"While these results are encouraging, due to the difficulties encountered during the logging program, we have not yet demonstrated the presence of commercial gas at this location. This will only be confirmed by a positive result from the planned production test".

Tullow Bangladesh Limited, (30%), operates Block 9 with co-venturers Niko Exploration (Block 9) Limited, a subsidiary of Niko Resources (60%), and Bangladesh Petroleum Exploration and Production Limited, (10%).
