Gas. Process. Stuff.

Coal, oil, or natural gas. Fossil fuels formed from the remains of old plants and animals. process usually used to extract oil and natural gas in which fractures in the Earth's surface are opened and widened by injecting water, chemicals, and sand at high pressure. Also called hydraulic fracturing.

This is how we do it.

Primary recovery first relies on underground pressure to drive fluids to the surface. When the pressure falls, artificial lift technologies, such as pumps, are used help bring more fluids to the surface. Sometimes, natural gas is pumped back down the well underneath the oil. The gas like to separate, to expand, and it does what it was always meant to do, it pushes the oil to the surface. Primary recovery often taps only 10 percent of the oil in a deposit.

Secondary recovery is the most widely used enhanced recovery technique. Water that is produced and separated from the oil in the initial phase of drilling is injected back into the oil-bearing formation to bring more oil to the surface. In addition to boosting oil recovery, it also disposes of the wastewater, putting it back where it came from. This can bring an additional 20 percent of the oil in place to the surface.

Enhanced recovery techniques are used to mobilize the remaining oil. There are three main approaches: thermal recovery, gas injection or chemical flooding.
