Some excerpts, with a somewhat revelatory comment following:
"Coal gasification and coal-to-liquid are some proven technologies available which can be successfully employed in Pakistan to reduce dependence on imported oil and natural gas.
In addition to coal, there are many waste materials like cow dung, municipal solid waste, industrial waste, rice husk, wheat and rice straw and other composite materials which can be used to produce bio gas, which can be used a substitute of natural gas for winter heating and CNG filling stations for vehicle fuels. If this waste-to-energy technology is adopted in Pakistan on a fast track basis, then the problem of gas shortage can be overcome within a few years.
Coal gasification offers one of the most versatile and cleanest ways to convert the energy content of coal into electricity, hydrogen, and other energy forms."

As you will see, this article was based on an interview with an oil industry expert who works for a Houston, Texas, company. A little digging reveals that company is owned by a much larger conglomerate - a Saudi Arabian conglomerate. You can do that little bit of mining on your own. You'll find it.
