Abstract
An apparatus for the downhole production of hydrocarbons. The apparatus includes a first pump coupled to a second pump. The first pump is powered by injection fluid contained in the tubing string; thus, eliminating the need for electrical connection cables or rotating rods. Typically, the second pump is powered by the first pump. The apparatus is capable of simultaneous injection and hydrocarbon production in a single wellbore. The coupling of the first and second pumps may further include a cross-over piece wherein the injection fluid and hydrocarbon production bypass one another.
