State-run Bapex has successfully done workover of onshore Srikail-4 gas well and initiated on test basis the gas flow at around 20 mmcfd, which is about three-folds of its previous production.
Bangladesh Petroleum Exploration and Production Company Ltd, or Bapex, is planning to supply the new gas to the national grid from next week, a senior official at the Bapex told the FE.
"We got new gas at around 3,200 feet beneath the surface in new gas zone, named E sand, with a pressure of around 2,950 per square inch, or psi," said the official.
Bapex got the new zone after 55 days of initiating the workover activities with its own manpower, he said.
Previously Srikail-4 was supplying around 8.0 million cubic feet per day, or mmcfd, of gas with around 600 psi before starting of the workover in August this year.
With the new gas, Srikail gas field's overall production will double to around 40 mmcfd.
Separately, Bapex is working to bring new gas from a new structure at Srikail East -1, some seven kilometres away from the currently producing Srikail gas field.
Bapex discovered commercially viable gas at Srikail East -1 in March this year.
Necessary pipeline is now being constructed to bring this gas, located at village Pakhjipur of Bangora in Cumilla, into the grid.
The work on land acquisition and construction of road is also going on, he added.
Around 12 million cubic feet per day, or mmcfd, of natural gas can be added to the gas grid once the new gas well starts commercial operation.
Bapex has estimated that the well might have around 70 billion cubic feet, or BCF, of natural gas.
There could be a cumulative 16 metres of gas layer at 3,071-metre depth of the new gas structure.
Bapex drilled some 3,482 metres from the surface to discover the new structure.
Country's overall natural gas output is currently hovering around 2,939 mmcfd, including re-gasified imported LNG to the tune of around 530 mmcfd, as on November 21, 2020.
Of the total natural gas output, Bapex is supplying around 67 mmcfd of gas from its eight operating gas fields against their cumulative production capacity of 145 mmcfd.
