Over 400,00 oil wells are now produced by rod drawn pumps. These vary in depths from "post holes" of less than a hundred feet to some of the deepest wells drilled, where the setting depth of the pump may be as much as 12,000 feet. The volume output of these pumps is just as varied as their setting depth. It may range from less than a barrel a day in small stripper wells to more than 2,000 barrels a day in wells where large bore pumps and high operating speeds are employed.
