Patent number: 9863415Abstract: A pumping assembly includes a hydraulic pump having a hydraulic ram tied to a reciprocating annular piston having a central bore. When the annular piston moves in an upward direction, the hydraulic ram moves toward an extended position extending from the housing. When the annular piston moves in a downward direction, the hydraulic ram moves toward a retracted position retracted within the housing. A polish rod extends up through the central bore of the annular piston and is held in position by a polish rod clamp positioned on top of the hydraulic ram. The polish rod moves with the hydraulic ram. Other pumping systems, devices, and methods are also disclosed.Type: GrantFiled: September 22, 2014Date of Patent: January 9, 2018Assignee: 1238585 ALBERTA LTD.Inventor: Perry L. St. Denis

Patent number: 9016361Abstract: A wellhead for a hydrocarbon-producing wellbore includes a wellhead body having an inner cavity, and a production fluid conduit. The production fluid conduit and the wellbore define a production fluid flow path. A stuffing box is positioned within the inner cavity. A leak containment structure within the inner cavity captures any fluid exiting the stuffing box. A fluid pump pumps fluids from the leak containment structure to the production fluid flow path.Type: GrantFiled: January 5, 2012Date of Patent: April 28, 2015Assignee: 1238585 Alberta Ltd.Inventor: Nicholas Donohoe

Patent number: 8523543Abstract: A pumping assembly includes a well head with a radial flow channel for pumped fluids. A spacer stand is secured to the well head. A hydraulic pump is provided with a housing secured to the spacer stand. The hydraulic pump has a hydraulic ram tied to a reciprocating annular piston having a central bore. When the annular piston moves in an upward direction the hydraulic ram moves toward an extended position extending from the housing. When the annular piston moves in a downward direction, the hydraulic ram moves toward a retracted position retracted within the housing. A polish rod extends up through the central bore of the annular piston and is held in position by a polish rod clamp positioned on top of the hydraulic ram. The polish rod moves with the hydraulic ram.Type: GrantFiled: December 17, 2004Date of Patent: September 3, 2013Assignee: 1238585 Alberta Ltd.Inventor: Perry L. St. Denis

Patent number: 8082734Abstract: A drive assembly for a reciprocating pump includes a support structure with a linear actuator mounted on the support structure. The linear actuator has a stationary portion and a movable ram portion. At least one direction altering cable guide is mounted to the movable ram portion of the linear actuator. At least one cable is provided having a first end and a second end. The first end is anchored to one of the support structure or the stationary portion of the linear actuator. The second end is adapted for attachment to a polish rod of a reciprocating pump. As the movable ram portion moves, the cable and cable guide configuration provide a mechanical advantage which results in the polish rod reciprocally moving a multiple of the distance travelled by the movable ram portion of the linear actuator.Type: GrantFiled: June 5, 2006Date of Patent: December 27, 2011Assignee: 1238585 Alberta Ltd.Inventor: Perry L.
