Case File Statements
| Goods & Services | Oil well pumps, gas well pumps, water well pumps; oil and gas well equipment comprised of steel, brass, nickel alloy, stainless steel or cast iron, used in oil or gas well holes or at the surface of oil or gas wells to pump or assist in the pumping of fluids from the subsurface to the surface, namely, subsurface oil and gas well pumps, sucker rod oil and gas well pumps and couplings for sucker rods, pump barrels, namely, the cylinders of the downhole pump and pump plungers, namely, devices that typically travel up and down in the cylinders, both which are piston mechanisms of sucker rod oil and gas well pumps used to seal and produce a pressure differential for lifting reservoir fluids into the subsurface pump and then to the surface, sucker rod pump balls and sucker rod pump seats used for sealing pressure, cages, namely, hollow structures containing sucker rod pump balls and which absorb the impact of the ball on the well pumping downstroke and guide the ball back to the center of the seat on the upstroke, oil and gas well pump anchors which optionally anchor the sucker rod pump in the tubing, polished rods, namely, joints in the string of sucker rods used in a rod pump artificial-lift system for enabling hydraulic seals to be made around the reciprocating rod string and through the injectable packing stuffing box, polished rod clamps for connecting polished rods to the reciprocating oil or gas well machinery at the surface, polished rod liners for sealing pressure around the polished rods and through the stuffing box, polished rod alignment tools, namely, sliding horizontal and vertical guides for aligning the reciprocating movement of the polished rod with stuffing box seals while maintaining a pressure seal, spiral sucker rod guides for centering the rod string in tubing, valve rods for connecting the rod string to the sucker rod oil and gas well pumps, pull tubes for connecting the rod string to the sucker rod oil and gas well pumps, sinker bars, namely, weight bars that connect the rod string and sucker rod pump for overcoming the effects of pressure and friction at the surface seal and sucker rod pump when additional weight is needed, seating cups for sealing static fluid pressure between sucker rod pump and oil and gas reservoir, seating nipples, namely, short sections of heavy wall tubular used for providing a sealing surface for seating cups and positive stop for sucker rod pump, stuck pump unseating devices, namely, tubing weights lowered onto the tubing anchor or bottom of a well bore used for unseating sucker rod oil and gas well pumps that are stuck in the seating nipple due to particulates, seat valves for use as shutoff devices in oil and gas well pipelines, pollution control stuffing boxes, namely, seal assemblies for providing monitor ports between two sets of packing and for sealing pressure around reciprocating polished rods and polished rod liners, so as to contain any well fluid leakage from spilling onto the surface, injectable packing stuffing boxes, namely, seal assemblies for sealing pressure around reciprocating polished rods and polished rod liners, so as to contain any well fluid leakage from spilling onto the surface, rotationally operated on and off tools, namely, key and socket mechanisms actuated by rotation, for connecting and disconnecting sucker rods to and from well pumps, which are remotely actuated from the surface when the oil and gas well pumps are pulled for servicing |
