In recent years, several trillion cubic feet (TCF) of natural gas have been added to the confirmed 10.5 TCF known as of 1996. Due to the fact that there has been comparatively little exploration to date, estimates of the total extractable natural gas resource in Bangladesh are uncertain and vary widely. An estimate of 20 TCF is gaining acceptance among experts, but some argue that experiences in comparable basins elsewhere in the world suggest that the ultimate recoverable resource could be as high as 50 TCF or even 100 TCF.
At the current rate of natural gas use in Bangladesh (1000 mmcfd), the current estimated proven reserves would last 45 years. Even if the present rate of use increases at 10 per cent per year, these reserves would last about 17 years. A reserve-production Reserves-to-production ratio of 17 is higher than that for most industrial countries heavily dependent on natural gas, examples being Norway, Canada, USA and UK. Here only the R/P ratio of gas is being considered for comparison. Relative to Bangladesh, these industrial countries have more diverse indigenous energy sources such as coal, oil and nuclear. The U.S. still uses coal to produce more than half its electricity.
There are huge resources of gas in Bangladesh. Places where gas is commercially refines include: Titas, Habiganj, Bakhrabad, Narshingdi, Megha, Sylhet, Kailashtilla, Rashidpur, Beanibazar, Fenchuganj and Salda Nadi.

In 2001, Petrobangla Director Major Raihanul Abedin initiated the national plan to decrease the use of using liguid fuels, by introducing natural gas conversion. He thought if cars could be converted to use cooking instead of rather harmful fuels, the carbon emission would decrease exponentially. He was given the permission by the Prime Minister Khaleda Zia to carry out his plans. As a result, Asian Development Bank funded his scheme and today more than 80% of Bangladeshi vehicles are run on gas which has lessened pollution significantly.
