Bangladesh Petroleum Exploration and Production Company on Thursday said that trapped gas had found its way out through the hole dug for setting up a tube well at Sher-e Bangla High School of Kasba in Brahmanbaria.
The school has been closed for an indefinite period as gas started coming out after the school authority had dug a hole for setting up a tube well on Wednesday.
The gas emission has panicked locals and generated interest among many media outlets.
‘What we have here is shallow-depth gas,’ said Bapex operation wing director Tofayel Ahmed.
He said, ‘There is no way to use the gas. So nothing can be done but waiting until the trapped reserve is exhausted.’
The reserve should not last long as it is stored 150 metre down the earth surface with pressure of approximately several hundred pound-force per square inch.
He said that gas reserves were usually found 3,500 metre down the surface.
He asked locals not to light any fire near the ground leaking gas.
He said that a team of BAPEX members was on its way to the capital after collecting samples from the field.
The school authorities said that the digging for setting up the tube well began Sunday under the supervision of the public health engineering department.
Kasba UNO Jahangir Hossain said that water and sand continued to come out with the leaking gas till Thursday afternoon.
He said that it would take 72 hours to have the test done on samples collected.
Two gas wells are within two and a half kilometres of the ground leaking gas at Shalda.
