Claim:
A plunger system for maximizing the liquid lift potential of a plunger arranged for vertical travel in a conduit in a gas/oil production well, the plunger system comprising: an elongated plunger body mandrel having an upper or first end and a second or lower end with a fluid transmitting bore extending longitudinally therethrough, from the second or lower end of the plunger body and into at least a central portion of the plunger body; a plurality of curvilinearly shaped, replaceable wear pads arranged in a controllably radially displaceable manner on the plunger body; and at least one fluid ejecting nozzle arranged extending through a side wall of the plunger body, providing gaseous fluid communication from the bore within the mandrel to an inner surface of at least one of the wear pads on the plunger body, for directing pressurized fluid from the lower end of the plunger body onto the inner surface of the at least one pad for biasing the wear pad radially outwardly.
