A method and apparatus are disclosed for producing a gravity separated well in which water and oil are permitted to separate under the influence of gravity. A pumping unit, including an oil pump and a water pump, is positioned in the well. A drive motor may be close coupled with the pumps. The pumping unit may be positioned in the oil region, the water region or in an interface region therebetween. A discharge line extends from the oil pump to a location above the earth's surface, while another discharge line extends from the water pump to a location adjacent to a water injection zone of the well. At least one of the pumps includes a remote intake for drawing fluid from the region in which the unit is not positioned. The technique permits the pumps to be positioned in the well and driven without the need for extended power transmission elements between the pumps.
