Appl. No.:

10/603482

Inventors:

Timothy H. Hunter - Duncan OK, US

Assignee:

Halliburton Energy Services, Inc. - Duncan OK

International Classification:

F04B019/00
F04B037/00

US Classification:

417486, 417 53, 92 69 R

Abstract:

A transmissionless variable output pumping unit comprising a multiple crankshaft pump driven by a prime mover. The apparatus includes an adjustment mechanism for adjusting a phase angle between first and second crankshafts. Plungers in the pump are disposed in cylinders forming part of a pumping chamber. When the phase angle is at a minimum, the plungers operate together for maximum discharge from the pump. When the phase angle is at a maximum, the plungers operate substantially opposite one another for zero discharge. The phase angle may be infinitely adjusted between the minimum and maximum.

Abstract:

A device for separating constituents of a fluid mixture includes an elongate vessel oriented at an acute angle to horizontal. The vessel is operable to receive the fluid mixture and direct the fluid mixture to flow in a convection cell spanning substantially a length of the vessel. The convection cell is formed by gravitational forces acting on the fluid mixture and is operable to deposit a heavy constituent of the fluid mixture about a lower end of the vessel and a light constituent of the fluid mixture about an upper end of the vessel.

Abstract:

A method of locating a wellbore feature, comprising delivering a mechanical position determination tool into the wellbore, selectively causing an undulating curvature of the mechanical position determination tool in response to a change in a fluid pressure, moving the mechanical position determination tool along a longitudinal length of the wellbore, and sensing a change in resistance to continued movement of the mechanical position determination tool. A mechanical position location tool for a wellbore, comprising pressure actuated elements configured to cooperate to selectively provide an unactuated state in which the mechanical position location tool lies substantially along a longitudinal axis and the pressure actuated elements further configured to cooperate to selectively lie increasingly deviated from the longitudinal axis in response to a change in pressure applied to the mechanical position location tool.

International Classification:

E21B 43/00
F04B 23/06

US Classification:

166105, 417529, 417552

Abstract:

A reciprocating apparatus for pumping pressurized fluid. The reciprocating apparatus comprises a plunger disposed within a cylinder, wherein the plunger is hollow and ported for enabling fluid within the cylinder to flow into the plunger. The plunger includes at least one outlet through which fluid within the plunger flows out of the plunger. In operation, the plunger retracts to displace fluid from the hollow body and into a discharge chamber, and the plunger extends towards the discharge chamber to discharge the displaced fluid. As the plunger alternately retracts and extends, fluid within the plunger continuously flows towards the discharge chamber.

International Classification:

F04B 49/00

US Classification:

417 27, 417273, 417 53, 417 63

Abstract:

An active valve system may be used to improve operation of the suction valve(s) of a positive displacement pump. As appropriate, the active valve system may apply a force to the suction valve directed to open and/or close the suction valve. By quickening the opening and/or closing of the suction valve, the pump may run at a higher speed and operate with less wear. Additionally, the active valve system may allow all suction valves of a pump to be held open for various purposes.

International Classification:

E21B 43/11

US Classification:

166297

Abstract:

A method for wellbore perforation in which a section of the wellbore to be perforated is isolated and purged of wellbore fluid to provide a clear path for laser beam transmittal. A laser beam emitter in the purged wellbore section transmits a laser beam pulse from the laser beam emitter to a target area of a sidewall and formation lithology of the purged wellbore section, thereby altering a mechanical property of a material of the sidewall and formation lithology and producing material debris. A liquid jet pulse of a liquid is transmitted immediately following termination of the laser beam pulse to the target area, thereby removing the material debris from the target area. This cycle is then repeated until the desired perforation depth has been achieved.

International Classification:

US Classification:

1662421

Abstract:

A method of forming multiple inclusions into a subterranean formation can include initiating the inclusions into the formation, the inclusions extending outwardly in respective multiple azimuthal orientations from a casing section, and flowing fluid into each of the inclusions individually, thereby extending the inclusions into the formation one at a time. A system for initiating inclusions outwardly into a subterranean formation from a wellbore can include a casing section having multiple flow channels therein, each of the flow channels being in communication with a respective one of multiple openings formed between adjacent pairs of circumferentially extendable longitudinally extending portions of the casing section. Another system can include a casing section, and an injection tool which engages the casing section and selectively directs fluid into each of the inclusions individually, whereby the inclusions are extended into the formation one at a time.
