Bangladesh is the seventh-largest producer of natural gas in Asia. Gas supplies meet 56% of domestic energy demand. However, the country faces an acute energy crisis in meeting the demands of its vast and growing population. Bangladesh is a net importer of crude oil and petroleum products. The energy sector is dominated by state-owned companies, including Petrobangla and the Bangladesh Petroleum Corporation. Chevron, ConocoPhilips, Statoil,Gazprom and ONGC are major international companies engaged in Bangladesh's hydrocarbon industry; with Chevron's gas fields accounting 50% of natural gas production.
Geologists believe the country's maritime exclusive economic zone holds one of the largest oil and gas reserves in the Asia-Pacific.Protectionism and a lack of technical capacity have impeded Bangladesh's potential to emerge as a major global hydrocarbon producer.
The British Raj-era province of Eastern Bengal and Assam was one of the world's earliest petroleum producers due to the discovery of oil and gas deposits in Assam, which included the Sylhet region. The Indo-Burma Petroleum Company drilled the first oil wells in Eastern Bengal between 1908 and 1914 in Chittagong District. The Burmah Oil Company discovered the first gas field in East Bengal in 1955. Industrial use of natural gas began in 1959. The Shell Oil Company and Pakistan Petroleum discovered seven major gas fields in the 1960s.
