why are oil and natural gas usually found together
Oil and natural gas are produced by the same geological process according fossil fuel suggestion: anaerobic decay of organic matter deep under the Earth's surface. As a consequence, oil and natural gas are often found together.In common usage, deposits rich in oil are known as oil fields, and deposits rich in natural gas are called natural gas fields.n general, organic sediments buried in depths of 1,000 m to 6,000 m (at temperatures of 60 Â° C to 150 Â°C) generate oil, while sediments buried deeper and at higher temperatures generate natural gas. The deeper the source, the drier the gas (that is, the smaller the proportion of condensates in the gas).
