Primary oil recovery
Primary recovery, also known as “primary production,” is the initial stage in the extraction process for oil and gas. In crude oil production, various methods of primary recovery can be used. Typically, the primary recovery process involves placing increased pressure on the oil within wells in order to force … See more The key to primary recovery is the fact that the hollow well shaft drilled to access the oil is designed to have a lower pressure than the oil that is deep in the … See more Once this point has been reached, secondary recovery techniques must be used, such as additional water injections which seek to force oil to the surface by … See more WebNov 5, 2007 · Assuming a conservative average overall recovery factor of 22% for the conventional proved reserves of crude oil discovered to date of 2,158 billion bbl would establish a global resource base of 9 ...
