ABSTRACT:
The method and apparatus for producing an oil well, by the provision of a pumpjack unit which reciprocates an engine assembly located within the upper extremity of a wellbore. The engine assembly has a power piston which hydraulically drives a lift piston by means of hydraulic fluid being transferred therebetween. The lift piston is directly attached to and reciprocates a string of sucker rod, which in turn reciprocates the downhole production pump.
The hydraulic fluid associated with the engine assembly is contained within a closed system, and the relative sizes of the power and lift pistons are of a ratio to cause the lift piston to travel a greater distance respective to the power piston, thereby enabling a relatively short stroke of the polish rod to impart the piston of the subsurface pump with a relatively larger stroke.
