State-owned Sylhet Gas Fields Limited (SGFL) has officially started supplying about 19 million cubic feet of gas per day (mmcfd) to the national grid.
The supply comes from well no 7 of the Kailash Tila gas field, declared abandoned earlier.
Md. Mahbub Hossain, Senior Secretary of Energy & Mineral Resources Division on Saturday inaugurated the gas supply activities.
“Although not too much in terms of the quantity, it is to the relief of Bangladesh, which is suffering an acute gas crisis,” an energy division official said.
According to the Energy Division, Bangladesh Petroleum Exploration and Production Company Limited-Bapex on 27 April found the new gas reservoir in Kailash Tila field, the main source for Sylhet Gas Fields Ltd, from an abandoned well through a work-over process. The well will regularly supply about 20 million cubic feet of gas per day (MMCFD).
Besides, 187 barrels of condensates have also been confirmed through a work-over process by logging, perfection and testing in the lower gas sand zone of the gas field.
Engr. Md. Abdul Jalil Pramanik, General Manager (Operation) & Project Director of SGFL told Bangladesh Post, “We supplied gas to the national grid experimentally on 7 May. After a successful test run, today (Saturday) we started supplying gas commercially through a function. Senior Secretary of Energy & Mineral Resources Division inaugurated the activities.”
Earlier in 2016, well no 7 of the Kailash Tila gas field was declared abandoned. The yield of Kailash Tila was on average 69 million cubic feet per day in 2016, but it dropped to 29 million cubic feet in January this year.
In February this year, Bapex started working on the well - on behalf of the SGFL Authority - which was completed by April. The well is now producing gas at 2800 psi.
It is expected that the current zone of the gas field will continue production for next several years, the ministry said adding, that the remaining recoverable gas reserves in the Kailash Tila field is 758 billion cubic feet (BCF) which could be gradually produced through different wells.
There are a total of seven wells in the gas field in Sylhet. Around 29 million cubic feet of gas is being produced from the currently operational (two) wells.
Kailash Tila Field was discovered by Pakistan Shell Oil Company (PSOC) in 1961. A gas well (Kailash Tila-1) was completed in June 1983 with the initial production of 30 MMCFD. Later, three more wells namely KTL-2 (1988), KTL-3 (1988) & KTL-4 (19996) were drilled in this field. Gas of Kailash Tila has a very high condensate ratio in comparison to Haripur Gas Field.
The well KTL-5 added to the field with a production capacity of 15 MMSCF per day with a condensate ratio 40 bbl/MMCF. Another well KTL-6 started producing from 8th August 2007.
A comparison of data from Petrobangla-the state-owned hydrocarbon corporation-shows that the country produced around 2324.7 mmcfd of gas per day, of which three local companies produce around 691 mmcfd, two International Oil Companies (IOC) produce around 945 mmcfd and imports around 688.1 mmcfd per day.
The country's total supply now stands at around 3100 MMCFD against a demand for about 4200 MMCFD. Of this, the country's 27 gas fields can supply 2300 MMCFD while the remaining gas is met by imported liquefied natural gas (LNG), which is costly.
