Gazprom International, the sole specialised operator of Gazprom's hydrocarbon prospecting, exploration and development projects outside the Russian Federation, has completed the construction of the Titas-19 well in the Titas field in the Bengal oil and gas basin in north-east Bangladesh. On 20 May, the well was signed over to the client.
Drilling work was completed with a small increase in the projected depth, to 3,880 metres. Tests on the deposit beds gave a gas influx rate of 425,000 cubic metres per day.
At present, the drilling equipment is being dismantled for further use at the Rashidpur field where drilling on the next well, Rashidpur-8, is planned.
Titas-19 is the seventh well built by Gazprom International under drilling contracts signed in 2012 with BAPEX and BGFCL/SGFL, subsidiaries of Bangladesh's state oil and gas corporation Petrobangla. Under the terms of the contracts, Gazprom International will construct and commission a total of ten production gas wells in six fields in Bangladesh.
Seven wells under these contracts have already been built: Shrikail-3, Titas-19, Titas-20, Titas-21, Titas-22, Begumganj-3 and Semutang-6; drilling work is underway on Shahbazpur-3. Some of these wells are already linked up to Bangladesh's central gas supply.
In 2012, Gazprom International signed two contracts to design and build ten production wells for the Petrobangla subsidiaries. The agreements provided for drilling work to be carried out at the Titas field (four wells), the Rashidpur, Semutang, Begumganj and Shrikail fields (one well each), and the Shahbazpur field (two wells). Most of the wells are directional inclined wells; their depths range from 2,900 to 4,050 metres down the wellbore. Work began in March 2013.
The Titas gas field is located 95 kilometres north-east of the Bangladeshi capital Dhaka, and was commissioned in 1967. Its total gas reserves are currently estimated at 230 billion cubic metres. The average daily yield, according to data from Petrobangla, is around 14 million cubic metres.
