oil recovery
Getting crude out
Oil recovery is the extraction of petroleum from underground reservoirs.
Primary recovery uses natural pressure; secondary recovery injects water or gas to maintain pressure; tertiary or enhanced recovery employs heat, chemicals, or other techniques to extract oil that resists simpler methods.
The new technology improved oil recovery rates by fifteen percent.
