petroleum oil extraction and recovery
Petropedia - What is Oil Recovery? - Definition from Petropedia
Petropedia explains Oil Recovery During crude oil extraction, an oil well goes through three recovery phases, namely primary, secondary and tertiary. In the primary phase, the natural pressure of an oil field pushes the oil to the surface and at times it can be accompanied by pumps.

Extraction of petroleum
Oil extraction and recovery Primary recovery. During the primary recovery stage (also called the 'Kareem Stage'), reservoir drive comes from a number of natural mechanisms. These include: natural water displacing oil downward into the well, expansion of the natural gas at the top of the reservoir, expansion of gas initially dissolved in the crude oil, and gravity drainage resulting from the movement of oil within the reservoir from the upper to the lower parts where the wells are located.

Enhanced oil recovery
Injection well used for enhanced oil recovery Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery.

Petroleum: Oil extraction and recovery
Tertiary, or enhanced oil recovery methods increase the mobility of the oil in order to increase extraction. Thermally enhanced oil recovery methods (TEOR) are tertiary recovery techniques that heat the oil, thus reducing its viscosity and making it easier to extract.

Why it's important to know the crude oil extraction process
Primary recovery is the first stage of crude oil extraction. In this stage, crude oil flows naturally under the base of the oil rig. The natural underground pressure in the oil well pushes the oil...

What is the Difference between Primary, Secondary & Enhanced
Traditional methods of oil extraction have been the primary and secondary methods, which, according to studies by the US Department of Energy, only exhaust between a quarter and half of a well's oil reserves. Such profligacy has been addressed by the development of a tertiary technique, more commonly known as enhanced oil recovery (EOR).

Oil Recovery from Petroleum Sludge by Solvent Extraction
A recovery of about 67.5% hydrocarbon oils was obtained, out of which 86.7% were aromatic. Gas chromatographic analysis of the extracted oil showed it contained the hydrocarbons in the range of C 9 -C 25, which is good petrochemical industry feedstock.

Primary recovery often taps only 10 percent of the oil in a deposit. Secondary recovery is the most widely applied 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.

Solvent extraction was used for oil recovery from high-moisture oily sludge. Freeze/thaw can improve the TPH content in recovered oil from solvent extraction. Recovered oil mainly consisted of relatively heavy petroleum hydrocarbon fractions. The solid residue had a decreased TPH content but an increased heavy metal content.

Petroleum production - Recovery of oil and gas | Britannica
Petroleum production - Petroleum production - Recovery of oil and gas: Petroleum reservoirs usually start with a formation pressure high enough to force crude oil into the well and sometimes to the surface through the tubing. However, since production is invariably accompanied by a decline in reservoir pressure, "primary recovery" through natural drive soon comes to an end.

• Tertiary recovery allows another 5% to 15% of the reservoir's oil to be recovered. • Tertiary recovery begins when secondary oil recovery isn't enough to continue adequate production, but only when the oil can still be extracted profitably. This depends on the cost of the extraction method and the current price of crude oil.
