How Is Natural Gas Extracted, Processed & Refined?
By Edwin Thomas; Updated September 29, 2017 Extraction refined-1.1-800x800.jpg" width="320" /> Natural gas extraction begins with drilling a well. These wells are purpose-drilled for natural gas, but because natural gas is often found in the same deposits as petroleum, sometimes natural gas extraction is a side-operation of oil extraction, or is pumped back into the well for future extraction. In a typical operation, the well is drilled, a concrete and metal casing is installed into the hole, and a collection pump is installed above it. Preparation and Transportation After being brought up from its subterranean deposit, the raw natural gas is first transported to a collecting point. Here, pipelines from all adjacent wells bring the raw gas together for pre-processing, which removes water and condensates. Then it is almost always pipelined to a processing plant. If this is not feasible, the gas is pumped into an underground storage facility for future pipelining and us...
