Exploration History of Bangladesh in petroleum/ Gas Sector


Bangladesh has been blessed with a heaven of natural resources among which natural gas has been proved to be a potential endowment for which it has already been identified to be the hub of energy in the South Asian region.  Bangladesh adopted a number of policies since the beginning of 1990s to facilitate the expansion of the private sector and increase the inflow of foreign investments in the energy sector. Due to the growing interests of the Multinational
Corporations (MNCs) in the energy sector of Bangladesh, there had been a tremendous optimism over Bangladesh's economic future. Bangladesh looked set to emerge as “South Asia's next success story." 
The exploration activity of petroleum products is over 100 years old in Bangladesh first exploration activity started with some topographic maps of Chittagong Hill Tracts and some simplified surveys were done. The first exploration started from 1914 to 1933 by Burma Oil Company (BOC). The second of phase petroleum exploration began after partition of Indian subcontinent.
Three international oil companies and the state owned oil company (OGDC) were active in different part of the country. During phase II, Shell Oil discovered the most successful  drilling  operation;  Rashidpur,  Kailashtila,  Titas,  Habigonj  and  Bakhrabad  gas fields were discovered. 
After the independence of Bangladesh in 1971, the petroleum exploration gathered pace. In this period, the first offshore gas field, Kutubdia was discovered. The country was first divided  into  23  major  blocks  including  offshore  area.  During  1995-2000,  the  foreign companies Fig.2 drilled 10 exploratory wells and discovered 1 offshore gas field (Sangu in 1996 by Cairns Energy) and two onshore gas fields (Bibyana in 1997 and Moulovibazar in 1998). After some more successful drilling by Tullow Oil, Bangura gas field was discovered  in 2004. BAPEX, (Petrobangla exploratory subsidiary) drilled two wells and discovered two gas fields, i.e. Shahbazpur in 1995 and Saldanadi in 1996. BAPEX drilled one well in late 2004 and announced discovery of Srikail gas field in Comilla in January 2005. It is very interesting data that the national oil companies of Bangladesh have a discovery success rate over 80% Fig.3 compared to the multinational oil companies. Digital multi fold seismic data acquisition started in 1977, when Prakla was engaged under the German technical Assistance Program. In 1978 Petrobangla started acquiring multi fold analog seismic data, Fig.4 but in 1979 it moved into the digital domain. During 1986-87 Shell recorded over 1,500 km of multi fold data and these are available in BAPEX Data Center.
