Abstract: A cyclonic debris evacuation apparatus and method for evacuating debris in a pumping system that forms between the plunger exterior and barrel interior. The apparatus is configured for use with a valve rod and has a cyclone component, cup component, ring component, and ring coupler component. The apparatus is also configured for use with a hollow valve rod and has a hollow valve rod coupler component, cup component, ring component, and ring coupler component. The cup component can be composed of a high density poly-fiber material that helps in creating a positive seal between the cup component and barrel interior during pumping operations, helping to direct solids into the cup component and thereby preventing them from travelling southward in the direction of the barrel and causing damage. In another embodiment, the cup component can include a specialized leading edge adapted to direct solids into the cup component.

Abstract: A sand check filter for preventing solids from reentering into a pump. The filter is designed to mount atop a conventional rod pump. The filter allows well fluid, that contains high solids, to pass through the pump under normal operation while eliminating the solids from being swept back into the pump barrel. The filter includes a sleeve that has radial flutes that allows the sleeve from hanging up, sticking to or wedging itself to the valve rod. The sleeve is rotated on the valve rod to create a valve effect atop the filter. This prevents the fluid from passing through the inner diameter of the screen and forces solids within the fluid to be redirected to the outer diameter of the filter. This allows the fluid to be filtered before reentering the pump.

Abstract: The rod guide and solids control assembly can be mounted on a rod string. The assembly can allow well fluid that contains high solids to pass through the pump under normal operation while eliminating the solids from being swept back into the pump barrel. The assembly can include a body portion coupled to a bristle that extends helically around the body portion. The body portion can be placed on a pump valve rod or hollow valve rod. On an upstroke, the bristles can be locked into place for trapping and lifting the solids. On a downstroke, the bristles can be rotated for leaving the solids higher and away from a pump intake. This can allow the solids to be lifted out of the pump and thereby prevent solids from collecting on a bottom portion of the pump. Multiple assemblies can be incorporated into the sucker rod string.

Abstract: A plate pump assembly for pumping various fluids including heavy crude. The plate pump assembly includes first and second chambers each having lower and upper valves. Primary upper and lower eccentric cams within the plate pump assembly are connected to an upper plate and a lower plate. A secondary eccentric cam is connected to a piston that separates the first and second chambers. A drive shaft of the assembly rotates the primary upper and lower eccentric cams to actuate the upper and lower plates alternately concealing and revealing the lower and upper valves for the first and second chambers. The drive shaft further rotates the secondary eccentric cam to actuate the piston alternately decreasing and increasing an area of the first and second chambers to receive fluids through the lower valves and compress the area within the first and second chambers to push the fluids through the upper valves.

Abstract: An actuatable wellbore isolation assembly comprising a housing generally defining an axial flowbore and comprising a mandrel portion, a first end portion, and a second end portion, a radially expandable isolating member positioned circumferentially about a portion of the housing, a sliding sleeve circumferentially positioned about a portion of the mandrel of the cylindrical housing, the sliding sleeve being movable from, a first position in which the sliding sleeve retains the expandable isolating member in a narrower non-expanded conformation to a second position in which the sliding sleeve does not retain the expandable isolating member in the narrower non-expanded conformation, and an actuator assemblage configured to selectively allow movement of the sliding sleeve from the first position to the second position.

Abstract: A valve rod guide is adapted to be coupled to the barrel of a subsurface pump or the like. The guide has head, neck, body, and base regions. A plurality of angled flutes are provided on the body, tapering downwardly for preventing solids from reentering the pump barrel after pump operations are ceased and thereby damaging pump components once pump operations are resumed. The interior diameter of the neck includes lower and upper grooves and a plurality of spiral radial grooves extending therebetween. The spiral radial grooves terminate at exit ports. During pump operations, solids are wiped from the valve rod, drawn into the spiral radial grooves, and accumulate in the lower or upper groove during downstroke or upstroke, respectively. During upstroke, the solids are expelled through the exit ports. A hardened insert may be positioned in the head region, providing a durable wear area for the valve rod as well as a tight fit, thereby preventing solids from escaping through a northern end of the guide.

Abstract: A light fence represented by aligned apertures in a plurality of wheels permits the passage of a light beam to a sensor to activate an electro-mechanical control for a lock. Such an arrangement avoids the sound-producing mechanical action of the typical tumbler lock and safeguards discovery of the opening combination. Rather than the typical case of a numerical sequencing combination, a novel approach is taken by using visual pattern recognition to align the apertures. The electro-mechanical control of the present invention additionally features optimized energy use, customizable settings, precision positioning, and an expansion of possible combination permutations by including direction of rotation.

Abstract: A debris-catching attachment device and method therefor is disclosed. When positioned in wellbore tubing, the device collects solid impurities found in well environments, thereby preventing the solids from settling onto the pump and its components when pumping operations are halted. The device comprises a ring having one of a plurality of brushes and a plurality of wiper segments coupled to a surface of the ring. As fluid is being forced naturally upward or is pumped, it flows past the components of the ring and is caused to rotate or spin in a cyclonic motion. During the first phase of well production, this directs the fluid and solids toward the tubing wall, allowing gas to escape upward. During the second phase of production, solids are caused to move toward the wall of the tubing, allowing any water and oil to move upward to the surface, with the surface tension dragging the solids along the wall of the tubing. The solids may accumulate on the brushes or wiper segments when pumping operations are halted.
