This paper describes the development and field testing of an automatic casing swab in northeast Ohio. This swab, operating in Clinton sandstone wells to depths of 5000 feet (1523 m), demonstrated an ability to increase gas production, improve orifice meter chart configurations and reduce operating costs on existing wells. On new wells, its use in lieu of tubing plunger and beam pump-sucker rod pumping systems has resulted in lower capital cost and enhanced profitability.

Development of the swab tool is continuing, and results to date indicate this system ultimately will be used in many of the 2500 Beiden & Blake wells in the Appalachian Basin.
