Patent number: 10941639Abstract: A production tubing is disposed in a wellbore formed in a subterranean zone. The production tubing extends from a surface of the wellbore to a downhole location at which hydrocarbons entrapped in the subterranean zone enter the wellbore. Multiple valves are disposed in the production tubing at respective multiple tubing locations. Each valve is configured to permit one-way flow of hydrocarbons in an uphole direction.

Patent number: 6976497Abstract: Liquid raising systems raise liquid from a system inlet to a system outlet without any moving parts below the system outlet. One or more closed cells are disposed at elevations between the system inlet and outlet. A liquid conduit leads from the bottom of each cell to the top of the next downstream cell. Gas pressure-differential between two next-adjacent cells causes liquid to flow through the liquid conduit to the next cell. The pressure-differential need be only enough to move the liquid between adjacent cells. The cells are cyclically filled and emptied by sequentially applying the gas at higher and lower pressures to adjacent cells, thus progressively moving liquid toward the system outlet. A cell can have a variety of shapes and sizes, so long as the cell gas inlet is above the liquid inlet, and the liquid outlet is below both the liquid inlet and the gas inlet.Type: GrantFiled: September 26, 2003Date of Patent: December 20, 2005Inventor: Brian J.

Patent number: 6193471Abstract: A process and system are provided for forming and transporting precise small volumes of liquid samples by means of controlled gas pressures. As the controlled gas pressures are changed at a multiplicity of control points in the fluid circuit, transitions take place involving the transport of small liquid samples. This transport is arrested by the geometry of the fluid circuit to produce a new state, which state remains stable until another transition is initiated by a change in the multiplicity of controlled gas pressures. Various combinations of control elements are described for effecting formation of fixed liquid volumes, transporting, mixing, and removing entrained bubbles from small liquid samples.Type: GrantFiled: June 30, 1999Date of Patent: February 27, 2001Assignee: PerSeptive Biosystems, Inc.Inventor: Carlton H.

Patent number: 4050854Abstract: A fluid lifting apparatus operable by air pressure applied alternately to first and second pairs of cylinders each of said cylinders having a main body part, a barrel and a bottom chamber in communications with a bottom inlet. Pressuring of the main body part of the chamber, closes a check valve at the inlet and forces fluid from the main body part, through a fluid flow valve, through the chamber and up the barrel to a production tubing segment and hence to the next higher cylinder. Emptying of the main chamber closes the fluid flow valve to prevent air from the production tubing. However, the valve is positively opened once fluid flow in the bottom chamber from the inlet is reinstituted. Air vent means to the surface and/or to the well annulus rapidly depressurizes the cylinders and hence speeds cycling between the alternate cylinder pairs.Type: GrantFiled: October 4, 1976Date of Patent: September 27, 1977Inventors: Judson A.
