Patent number: 9869165Abstract: 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 comprises 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.Type: GrantFiled: October 15, 2014Date of Patent: January 16, 2018Assignee: Well Master CorpInventors: Kevin W. Hightower, David A. Green, Neil W. Longfellow, Robert E. Bender

Patent number: 8201629Abstract: A staging tool arrangement for gas well production assistance, comprising an elongated staging tool having an elongated upper portion and an elongated lower portion. The upper portion has a sliding relationship with the lower portion thereof. A displaceable annular seal is arranged about the lower portion. A displaceable enclosure is arranged on the elongated lower portion so as to slidably expose and to slidably enclose the annular seal.Type: GrantFiled: September 25, 2009Date of Patent: June 19, 2012Assignee: Well Master Corp.Inventor: David A. Green

Patent number: 8162053Abstract: A elongated plunger assembly for pressurized, conduit-enclosed travel utilized in recovery of hydrocarbon deposits in a ground penetrating oil or gas well. The plunger comprises an elongated mandrel, a plurality of radially movable curvilinear wear pads circumferentially disposed adjacent each end of the elongated mandrel, a pad-edge retaining housing extending on at least one end of the elongated mandrel to enclosably retain the longitudinally distal end of a circumferential array of wear pads onto the mandrel, and a centrally disposed wear pad securement ring arrangement to permit release of a worn wear pad, replacement of the worn wear pad at an inner longitudinal edge thereof, thus to permit simple field-accessable removal and replacement of any particular “conduit-worn” “wear” pad from the mandrel of the plunger.Type: GrantFiled: July 14, 2009Date of Patent: April 24, 2012Assignee: Well Master Corp.Inventors: David A. Green, Robert E. Bender

Patent number: 7793728Abstract: A plunger in a plunger lift system in an oil and gas well includes shaped grooves spaced along the plunger body, angled fins or below the grooves, an elongated interior cavity open at the bottom, and passages connecting the interior cavity to the grooves. The shape, sizing and spacing of the grooves improves plunger seal and decreases liquid loss during plunger lift. The flutes or fins spin the plunger to clean the tubing string and prevent the plunger from becoming stuck in the lubricator. The interior cavity lightens the plunger and, in combination with the passages, improves the seal created by the shaped grooves.Type: GrantFiled: July 8, 2008Date of Patent: September 14, 2010Assignee: Well Master CorpInventor: Robert E. Bender

Patent number: 7748448Abstract: An oil and gas well production unit for the retrieval of oil and gas from a diminishing oil and gas production field. The unit comprises a well casing within the field attached to a lubricator assembly. A plunger is arranged for reciprocable travel within a tubing in the casing and the lubricator to assist in the production of oil and gas removal from the oil and gas well production unit. A plunger examination port is arranged within the lubricator assembly to permit determination of the amount of wear of the plunger without having to remove the plunger from the lubricator assembly.Type: GrantFiled: March 7, 2007Date of Patent: July 6, 2010Assignee: Well Master CorpInventor: Robert E.
