This oil and gas migrates upward through the porous rock, as it is less dense than the water which fills the pores. A common dome formed by folded sedimentary rocks is shown in Figure 1. Natural gas is captured by drilling a hole into the reservoir rock. Most often, the natural gas is under pressure and will come out of the hole on its own. In some cases, pumps and other more complicated procedures are required to remove the natural gas from the ground.
Natural gas is transported from wells to urban centres, where it is used by large pipelines.
Such pipelines criss-cross Canada and most of the industrialized world. Use of Natural Gas Natural gas is a very versatile fuel which can be used for space and water heating, process heat for industry, electricity generation, cooking, mechanical power and transportation . In the future, increasing concerns about urban air pollution may lead to increased use of natural gas as a transportation fuel. Furnaces which burn natural gas to provide space heating and hot water for homes and businesses are the largest users of natural gas. The high efficiency of gas furnaces and the low price of natural gas have made it the most popular heating fuel in cities where there are distribution networks.
