During primary recovery, the reservoir's natural pressure of the reservoir or gravity drivedrives oil into the wellbore, combined with artificial lift techniques (such as pumps) which bring the oil to the surface. But only about 10 percent of a reservoir's original oil in place is typically produced during primary recovery.<ref name=Enhanced/>

But [[petroleum]] isn't the only thing trapped in the earth. Water hides there too. Sooner or later, the reservoir begins producing water, along with oil, and it becomes uneconomical to continue. The oil companies will then re-inject the water back into the reservoir. This stage of production is called [[secondary recovery]].<ref name=Enhanced/>
