After four months of work, Petrobangla has confirmed the restoration of gas from a previously closed well at the Kailashtila gas field in Sylhet.
On Thursday, the state-run company announced that following a successful workover, the Kailashtila-1 well is now producing 5 MMCFD, which is expected to be connected to the national transmission line within two to three days.
Shafiqul Islam, project director of the Kailashtila-1 workover, said the well is one of the country’s oldest, first producing gas in 1983. Production had stopped after 2019.
“With the workover completed, the well is expected to yield 5 million cubic feet daily for the next 10 years,” he said.
Petrobangla said the workover, using BAPEX’s rig Bijoy-12, began on Aug 12.
The Kailashtila field, discovered in 1961, has eight drilled wells. By Jun 30, 2024, the field will have produced 812.17 billion cubic feet of gas from proven reserves of 878.80 billion cubic feet, or 92.42 percent of recoverable reserves.
In November 2023, gas flow of 5.85 MMCFD was restored from Kailashtila-2 via workover. Last year, drilling Kailashtila-8 also succeeded, producing 14 MMCFD.
