Abstract
A pad plunger assembly, for use in gas well tubing, includes an elongated mandrel having opposite ends and a longitudinal axis extending between the opposite ends, a pair of opposite end members each attached to one of the opposite ends of the mandrel, and a seal-forming pad subassembly disposed about the mandrel and between the opposite end members thereon. The pad subassembly has an outer exterior surface of an annular concave configuration formed by opposite end portions of the outer exterior surface being disposed farther radially outwardly from the longitudinal axis of the mandrel than an intermediate portion of the outer exterior surface is disposed radially outwardly from the longitudinal axis of the mandrel such that a frictional seal which generates reduced friction is provided on the interior wall surface of the gas well tubing.
