More gas found in Noakhali's Sundalpur-4 well, may add 7 mmcf gas to national grid daily

More gas has been discovered at the Sundalpur-4 appraisal-cum-development well in Bara Charigaon village of Nabipur union under Senbag Upazila of Noakhali, with preliminary estimates suggesting the well could supply around 7 million cubic feet of natural gas to the national grid per day.

Mohammad Mozammel Haque, project director of the Sundalpur-4 appraisal-cum-development well drilling project, confirmed the discovery today (7 October), saying a Drill Stem Test (DST) is currently underway.

He said the presence of gas was formally confirmed yesterday (6 October) after gas was ignited at the mouth of the pipe installed in the well following completion of drilling.

"The DST will be completed within the next four to five days. After that, we will be able to confirm the total amount of gas reserves," Mozammel said.

He said preliminary estimates suggest the well could supply around 7 mmcf of gas per day to the national grid.

The Bangladesh Petroleum Exploration and Production Company Limited (BAPEX) confirmed the presence of gas at the well yesterday afternoon.

Drilling of the well began on 28 July. According to BAPEX sources, the well was drilled to a depth of 1,578 metres using directional drilling and Measurement While Drilling (MWD) technology.

Gas-bearing layers were found at depths between 1,420 and 1,460 metres.

Earlier, Sundalpur-1, Sundalpur-2 and Sundalpur-3 wells were drilled in the Sirajpur area of Companiganj Upazila under the same gas field.

Although the new well is located in Senbag, it was named Sundalpur-4 as it is part of the same underground gas field structure.
