ABSTRACT:
A system for recovering contaminating hydrocarbon fluid product from below ground includes water and product withdrawal pipes disposed within a well and connected to pumps adapted to remove water and product respectively. Admixture of the two fluids is precluded by the inclusion of a separator tube surrounding the water withdrawal pipe and having its bottom opening disposed well below the level of the fluid product. By locating the bottom intake of the water withdrawal pipe at a lower level than the bottom intake of the product withdrawal pipe and within a surrounding zone normally occupied by the product, hydrostatic pressure and the difference in specific gravity of the water and product insures separation of the product and water as the respective pumps individually remove same through the two pipes.
