Patent number: 11255171Abstract: A pump can include a plunger and a barrel, at one stroke extent flow being substantially restricted between the plunger and the barrel at spaced apart positions and a plunger interior passage in filtered communication with a fluid chamber between the positions, and at an opposite stroke extent the fluid chamber being in communication with the standing valve. A method can include displacing a plunger in one direction, thereby receiving filtered liquid into a fluid chamber, and b) displacing the plunger in an opposite direction, thereby transferring the liquid to a barrel interior passage. A system can include an actuator that reciprocates a rod string, and a pump including a plunger with a traveling valve, a barrel with a standing valve, and a filter that filters liquid which flows from a tubing string to a compression chamber disposed between the traveling valve and the standing valve.Type: GrantFiled: May 14, 2019Date of Patent: February 22, 2022Assignee: Weatherford Technology Holdings, LLCInventors: William C. Lane, Douglas Hebert, John Stachowiak, Jr.

Patent number: 10883349Abstract: A wellbore completion is configured for multiple forms of artificial lift. A downhole assembly on production tubing defines a production port communicating a throughbore with the wellbore annulus. A bypass, such as a snorkel or riser tube, on the assembly also communicates the throughbore between the packer and the production port with the annulus. A packer on the assembly seals in the annulus downhole of the production port and bypass. The assembly can then be configured for any selected artificial lift. To do this, at least one isolation (a sleeve insert, a sliding sleeve, a check valve, or a rupture disk) selectively prevents/allows communication via one or both of the production port and the bypass as needed. Additionally, removable lift equipment, including jet pump, gas lift valve, plunger assembly, rod pump, piston pump, or standing valve, is selectively inserted into the assembly's throughbore as needed.Type: GrantFiled: September 22, 2017Date of Patent: January 5, 2021Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Thomas Scott Campbell, Manish Agarwal, Jeffrey J. Lembcke, Michael C. Knoeller, Toby S. Pugh, William C. Lane

Patent number: 9068444Abstract: A velocity string deploys in production tubing of a gas well (or a gassy oil well) to help lift fluid toward the surface. The velocity string reduces flow area in the production tubing so that a critical flow velocity can be reached to lift liquid. Overtime, the reservoir pressure and resulting gas flow may decrease such that less liquid is produced toward the surface. At such a stage, operators then expand the velocity string to further decrease the flow area in the production tubing, which can produce the needed critical flow velocity to allow produced liquid to be lifted toward the surface.Type: GrantFiled: February 8, 2012Date of Patent: June 30, 2015Assignee: Weatherford Technology Holdings, LLCInventors: William C. Lane, Deborah L. Banta

Patent number: 8858187Abstract: A downhole pump has a barrel and a plunger movably disposed therein. The gap between the barrel and plunger has first and second seals. The barrel and plunger each have a one-way valve restricting fluid passage out of it. A filter or screen is disposed on the plunger between the first and second seals. In a downstroke, fluid and particulate in the barrel transfers into the plunger. In an upstroke, fluid and particulate in the plunger lifts uphole. At the same time, a volume in the barrel fills with fluid and particulate. During either stroke, the first seal prevents particulate uphole of the plunger from passing into the gap. The filter or screen, however, prevents at least some particulate (i.e., most or larger particulate) inside the plunger from passing out of the plunger with fluid flowing into the gap between the first and second seals.Type: GrantFiled: August 9, 2011Date of Patent: October 14, 2014Assignee: Weatherford/Lamb, Inc.Inventor: William C.

Patent number: 7314089Abstract: Oil is recovered from a borehole using a pump having limited high temperature breakdown resistance. The pump is located in a borehole having a cooling zone, in which the temperature of the well fluid is reduced to, or below, the temperature at which the temperature breakdown resistance of the pump is commercially acceptable. In one embodiment, the pump is a positive displacement pump which is mechanically driven from the well head location, such as through a rotating rod. The cooling zone is provided by positioning and controlling the pump to maintain a sufficiently low pressure at the pump intake to cause a portion of the liquid well fluid to vaporize prior to entry of the liquid into the pump, creating bubbles which pass upwardly in the wellbore in a zone passing the pump. The evolution of the vapor cools the well fluid to the acceptable temperature.Type: GrantFiled: August 26, 2003Date of Patent: January 1, 2008Assignee: Weatherford/Lamb, Inc.Inventors: William F.
