Oil and gas veteran Steve Antry is the chairman and CEO of Eagle Energy Resources. A resident of Tulsa, OK, Steve Antry supervises the company’s natural gas exploration and extraction operations.
A fossil source of energy, natural gas is found deep beneath the surface of the earth. A colorless, odorless matter, it has many compounds, the largest of which is methane, which is made of carbon and hydrogen atoms (CH4). Other components of natural gas include natural gas liquids and nonhydrocarbon gases like water vapor.
Natural gas is formed by decaying processes that take millions of years. The remains of animals and plants that lived and died millions of years ago were gradually covered by thick layers of sand, silt, and rock both on the earth's surface and ocean floor. Over time, the pressure and heat from these layers turned the remains into coal, oil, and natural gas. Today, humans drill deep into the subsurface layers to extract fossil fuels and natural gas for use as energy.
To find natural gas, geologists study earth rock formations to locate sites that bear features consistent with areas where natural gas has been found, then use techniques like seismic surveys to know whether the resource could be present. Seismic surveys sometimes involve using thumper truck machines to pound the earth, sending seismic waves into the ground. These waves are then interpreted to determine the geology of the subsurface. If there is a possibility that natural gas is present, an exploration well is drilled.
