Abstract
A pumping apparatus is set forth for use in a flowing well which flows into the well from formations on the exterior thereby producing a mix of oil and water. A column is accumulated where oil stratifies on the top. An oil producing pump is positioned to draw from the top portions of the column and produce oil to the surface through a production tubing string in response to operation of a sucker rod actuated pump. The sucker rod string in addition operates a water expelling pump on the opposite stroke, thereby forcing water out of the accumulated column of liquid. The water is returned from the cased well into a water receiving formation on the exterior.
