Paper: Innovative Developments in Casing Plungers Broaden Field Applications and Increase Production in Upper Anadarko Basin

An innovative patented casing plunger offers production increases in Panhandle reservoirs. Several years ago, casing plungers were introduced to Panhandle oil & gas reservoirs. While several applications responded well, others were limited by wellbore conditions and reservoir fluids. Those problems have been addressed in a recently patented casing plunger, providing substantial increases in daily production and recoverable reserves. Design details, working models and producion data will be presented to encourage broader applications of casing plungers as reserves and bottom-hole pressures continue to decline. Current applications have been successful in all weights of 4-1/2" casing tapered strings common in Upper Anadarko Basin. Wellbore fluids of all combinations of oil, gas, condensate and water have been produced with the new casing plunger. Applications for 5-1/2" casing are also presented. Reasonable installation costs and recoverable tangible assets can be expected.
