Bibiyana Gas Field (or simply Bibiyana) is a gas-condensate field located in the Habiganj district of Bangladesh. It is operated by Chevron Corporation, along with other fields such as Jalalabad and Moulavi Bazar. Bibiyana is also considered as Bangladesh's largest gas-producing field.
Bibiyana was discovered in 1998 and is still undergoing expansion until now. In 2012, four wells were drilled here and more drilling is planned in the coming years. The expansion in 2014 is very vital to the country, as it is expected to boost Chevron's total production of natural gas.
Aside from being the largest natural gas source in Bangladesh, Bibiyana is also considered as one of the most useful discoveries in the country because of the reserve's vast area and quality.
