Casing pumps can increase production while cutting costs in wells producing up to 40-b/d fluid and 350-Mcfd gas. Picking the oil and gas well suitable for this application is the key to obtaining such benefits. This article describes the method for making that decision. Casing pumps eliminate gas-locking. The costs of maintaining and operating a casing pump are less than that for the conventional sucker rod pumping system. Like plunger lifts, casing pumps are self-contained pumps that use the well's pressurized gas as the energy source, in turn allowing all of this energy to be sold. Yet, while plunger lifts normally require several hundred pounds of shut-in pressure, casing pumps typically require only 100 lb of shut-in pressure to operate. Casing pumps require no tubing, sucker rods, timers, or outside sources of energy.
