In the context of severe energy crisis all over the world, Sylhet’s Biyanibazar gas field showed Bangladesh a ray of hope. From Monday (November 28), about 8 million cubic feet (cft) of gas will be added to the national grid every day from the abandoned well No. 1 of this gas field.
Managing Director of Sylhet Gas Field Limited (SGFL) Md. Mizanur Rahman confirmed the news.
Mizanur Rahman said that more than 70 billion cubic feet of gas is stored at a depth of 3,254 meters in well No. 1 of Bianibazar gas field. After the gas pressure test, it was found that the well is capable of supplying 10-12 million cubic feet of gas per day. However, considering various technical aspects, 8 million cubic feet of gas will be supplied daily. It is expected to yield 125-130 barrels of condensate gas per day.
Bangladesh Petroleum Exploration and Production Company Limited (BAPEX) started the drilling of this abandoned well No. 1 in Biyanibazar in September this year. On Sunday night, gas has been experimentally supplied from well No. 1, which has been abandoned for five years.
General Manager (Administration) of Sylhet Gas Field Limited (SGFL) Abdul Jalil Pramanik said, “We have completed all the experimental work on Sunday afternoon. After the gas pressure testing work, all the technical preparations have been completed for gas supply to the national grid at the final stage. If all goes well, gas will be supplied to the national transmission line from 12 midnight on Sunday.
According to SGFL sources, gas extraction started in 1991 from well No. 1 of Biyanibazar gas field. It was closed in 2014. Mining resumed in 2016, but was stopped again at the end of that year. The well was abandoned since early 2017. After that, BAPEX found gas reserves by conducting exploration in that well.
The Biyanibazar gas field is under Sylhet Gas Field Limited (SGFL). 7 million cubic feet of gas per day is being supplied to the national transmission line from well number 2 of this gas field.
Mizanur Rahman said that three-dimensional seismic survey is going on in different areas of Biyanibazar. New gas fields are likely to be discovered from that survey. By the year 2025, all the companies in the country have adopted a plan to increase 618 million of gas through drilling of about 46 wells.
At present there are five gas fields under SGFL. These are Haripur gas field, Rashidpur gas field, Chatak gas field, Kailashtila gas field and Biyanibazar gas field. Among them, Chatak gas field is abandoned. The remaining 12 wells are currently producing 91 million cubic feet of gas per day.
