Plunger lift arrangement

A method of extracting hydrocarbon fluids from a gas well system comprising the steps of:

• forming an elongated plunger with an elongated bore extending longitudinally therethrough;
• arranging a plug-containing central chamber within the elongated bore;
• placing a plug within the plug containing central chamber wherein the plug is movable longitudinally within the central chamber;
• placing the plug containing plunger in an inner tubing a gas well system;
• dropping the plug containing plunger in the inner tubing of the gas well system;
• enabling the plug to move to an upper seat engaging position in the central chamber;
• and
• pushing a slug of hydrocarbon fluid upwardly within the inner tubing ahead of the plunger as the plunger moves upwardly within the inner tubing of the gas well system.

A plunger for extraction of hydrocarbon fluids from a gas well system wherein the plunger is arranged to move upwardly and downwardly in an arrangement of inner tubing within the gas well system, the plunger comprising:

• an elongated housing sleeve having a longitudinally directed bore;
• an elongated central chamber within the longitudinally directed bore, the central chamber having a plug nestable seat at each end thereof;
• and
• a plug displacably arranged within the central chamber so as to seal the bore during travel of the plug in a first direction in the inner tubing, and to permit flow of fluid through the plunger as the plunger travels in a second direction in the inner tubing.
