Pakistan has 33 tcf tight gas reserves

Pakistan has an estimated tight gas reserves of 33 trillion cubic feet (tcf) which are more than the existing estimated natural gas reserves of 27 tcf in the country, said the Deputy Managing Director (operations) of Sui Southern Gas Company (SSGC) Syed Hassan Nawab. He also said that the country will have sufficient natural gas if tight gas is explored with the help of advanced technology. He pointed out that the government has prepared the draft policy for tight gas and it is currently with the Council of Common Interest (CCI) and this will be approved soon.
DEFINITION: 1.Unconventional natural gas that's trapped in hard rock, sandstone or limestone formations that is impermeable and non-porous.
2.Gas found in sedimentary rock that is cemented together so tight that flow rates are very low. Extracting tight gas usually requires enhanced technology like"hydraulic fracturing" where fluid is pumped into the ground to make it more permeable.
