On April 25, Gazprom International completed the construction of the Srikail-4 production well in the southeast of Bangladesh. The construction started on 15 February 2016 under a contract with BAPEX, a Bangladeshi oil and gas company.
The drilling of the slanted well with a depth of 3,512 m led to the discovery of a new layer, which gave a maximum daily flow rate of 580 thousand cubic meters of gas during tests. The daily yield of gas following the drilling of the previously discovered layers amounted to 252 thousand cubic meters per day.
The Srikail-3 well, which was drilled by Gazprom International at the same field in 2013, gave a daily flow rate of 618 thousand cubic meters of natural gas per day during tests.
The drilling of the Srikail-4 well was commenced within the framework of the turnkey project for construction of five wells under the agreements concluded by Gazprom International and BAPEX, BGFCL and SGFL (subsidiaries of Petrobangla, Bangladesh National Oil, Gas and Mineral Corporation).
In the end of 2014, within the framework of its first joint project with Bangladesh, Gazprom International, Gazprom's sole specialized enterprise for hydrocarbon field exploration and development projects outside the Russian Federation, entirely fulfilled its obligations under two drilling contracts signed on 26 April 2012 with BAPEX, BGFCL and SGFL, Petrobangla's subsidiaries. In accordance with these agreements, ten wells were designed and built at six fields of Bangladesh. Tests showed that maximum total production rate of the wells amounted to 5.1 million cubic meters per day, which is equal to 16.8% of Petrobangla’s production volume and to 7.5% of the total yield in the country.
In September 2015, Gazprom International and the units of Petrobangla, Bangladesh National Oil, Gas and Mineral Corporation, signed two supplementary agreements to design and build five new wells: three wells at the Rashidpur field, one well at the Srikail field and one well at the Bakhrabad field.
A total of 26 gas fields have been discovered in Bangladesh, 2 of which are located on the shelf of the Bay of Bengal. According to local media, BAPEX (both independently and together with international partners) discovered 7 gas fields: Saldanadi, Fenchuganj, Shahbazpur, Semutang, Sundalpur, Srikail and Rupganj.
Petrobangla estimates total proved hydrocarbon reserves of Bangladesh at over 15 trillion cubic feet (more than 400 billion cubic meters).
