A commercial influx of gas with the flow rate of 850 thousand cubic meters per day was obtained on Wednesday, November 1, while testing the first interval of the Shahbazpur East-1 well located at the Shahbazpur gas field on Bhola Island in southern Bangladesh.
“The successful testing of the first interval has confirmed survey forecasts,” says the Director of the Gazprom International office in Bangladesh, Nikita Shut. “Once all the promising intervals of the well are tested, BAPEX will have valuable data enabling it to significantly upgrade reserve estimates for the Shahbazpur gas field. A rough estimate now could put 1P+2P reserves at 34 billion cubic meters at the minimum, while previous estimates were in the region of 19 billion cubic meters. We are grateful to BAPEX experts for their invaluable logistical and technical support during the construction of the well”.
The project operator, Gazprom International, continues testing the well. The company plans to finish testing by November 20.
Drilling at Shahbazpur East-1 is part of stage three in the well construction project in the Republic of Bangladesh, which began in August this year. Under a contract signed in March between Gazprom International and the Bangladesh Petroleum Exploration and Production Company BAPEX (part of the Petrobangla national corporation), the operator will design, construct and commission two exploratory wells, Shahbazpur East-1 and Bhola North-1. Both are located on Bhola Island in southern Bangladesh. Each well is about 3500 meters deep. A total of four development and exploratory wells have been drilled at Shahbazpur since 2008, two of which – by the efforts of Gazprom International.
The Gazprom operator has been involved in the design and construction of a number of wells at Bangladesh gas fields since 2012. Over four years, the company designed and constructed 15 exploratory and development wells at seven gas fields in Bangladesh. This has secured a daily supply of about 6 million cubic meters of gas into the national energy system, which accounts for 20 per cent of total production of Petrobangla and about 10 per cent of total gas output in Bangladesh.
Gazprom’s main partner in Bangladesh is the national oil, gas and mineral corporation, Petrobangla.
According to the corporation, total proved hydrocarbon reserves in Bangladesh amount to over 400 billion cubic meters; the total annual output of natural gas amounts to 27 billion cubic meters, given existing demand for over 30 billion cubic meters.
A total of 26 gas fields have been discovered in Bangladesh, including two on the shelf of the Bay of Bengal.
No survey and exploration of new gas fields had been done in Bangladesh in the 10 years prior to 2013, which led to the adoption of a program to drill new wells.
The Bangladesh government contacted Gazprom in 2010 requesting its involvement in the survey and exploration of hydrocarbon fields in Bangladesh and in the construction of a unified gas supply system.
