Natural Gas
• Natural Gas is an important fuel found in oil bearing rocks above the oil
Extraction
• These rocks have millions of tiny holes which act like a sponge and soak up the gas as it is formed
• Above the rock there is a layer of non-porous rocks that trap the gas underground and stop it from leaking out to the surface

Composition
• Natural gas is made up many gases like methane, ethane, propane and butanes
Discovery
• It was discovered in 1952 at Sui, Baluchistan by Pakistan Petroleum Limited while drilling in search of oil
• The gas field is considered to be one of the largest in the world

Distribution to Multan
• Another pipeline to Multan was completed in 1958 to supply gas to the thermal power station and fertilizer plant.
• This pipeline has been extended to Faisalabad where another gas-fired power station has been set up and it has been further extended to Lahore.

Distribution to northern areas
• It was also taken to Rawalpindi, Islamabad and Peshawar.
Distribution to Quetta
• A pipeline also goes to Quetta from Sui. More gas fields have been discovered since then.
Liquefied Petroleum Gas LPG
