Filed:

Aug 19, 2005

Appl. No.:

11/208204

Inventors:

James H. Holt - Conroe TX, US
Clark W. Beam - Madisonville TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 17/10

US Classification:

1662416, 1662422, 1662417, 166 651, 1662421

Abstract:

One or more control lines or other types of lines can be run past a downhole tool such as a side pocket mandrel, for example, in a longitudinal groove with a retaining feature for the control line where the assembly leaves little to stick out and get damaged on run in or on pulling out of the hole. In the preferred version, the groove is a dovetail and at least one retainer can be slipped into the dovetail. Lateral bores into the dovetail allow pins to be driven into a wedge shaped retainer to force it against the control line or lines such that the shape of the dovetail and the shape of the wedge retainer trap the control line within the dovetail. Upon assembly, nothing sticks out from the dovetail or the downhole tool.

Appl. No.:

13/154642

Inventors:

Hai H. Nguyen - Houston TX, US
James H. Holt - Willis TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 43/00

US Classification:

166372

Abstract:

An insert device can straddle an existing production string port into the annulus such as through an open sliding sleeve so that annulus access into the production string is available. An injection string is associated with the insert to allow placement of the injection fluid at the desired location even if that location is below an isolation packer. The port can be part of an existing ported sub such as a sliding sleeve. Alternatively, the port can be created at a desired location and the insert supported with an anchor so that spaced seals straddle the port that is created to allow injection access from the annulus into the production tubing. The produced fluids pass around the injection tubing and through the insert body to get to the surface. The insert can be removed if needed.

Appl. No.:

09/803635

Inventors:

James Holt - Conroe TX, US

Assignee:

Weatherford/Lamb

International Classification:

E21B034/06

US Classification:

166/321000, 137/155000

Abstract:

The present invention provides an improved cross-over housing for a gas lift valve. In the present invention, the series of radial apertures, or jets, typically utilized within the cross-over housing of a production pressure operated gas lift valve are removed. In their place, a substantially continuous through opening is employed, having an area somewhat greater than the area of the pressure chamber seat. This avoids the occurrence of sonic flow, or critical flow, within the jets of the prior art which hampered the ability of the pressure chamber valve to close. The new configuration for the cross-over housing allows the bellows within the pressure chamber to sense the decrease in production fluid pressure, or tubing pressure, as gas is injected, allowing the pressure chamber valve to be reseated.

International Classification:

E21B033/00

US Classification:

166/285000, 166/117500, 166/153000

Abstract:

Well completion cement may be pumped through a side pocket mandrel that includes parallel rows of filler sections to exclude cement from void space within the side pocket tube. The filler sections are drilled with cross-flow jet channels and surface upsets to stimulate scrubbing turbulence by well working fluid behind a cement wiper plug. The wiper plug includes leading and trailing groups of wiper discs secured to an elongated shaft. The two wiper groups are separated by a distance that permits the leading seal group to gain traction seal before the push seal on the trailing wiper group is lost. A spring centralizer spans a center section of the shaft between the two wiper groups to maintain axial alignment of the shaft as the plug traverses the length of a mandrel.

US Classification:

137 1, 1375125, 137540

Abstract:

A valve having an outer housing defining a central bore with a fluid inlet and a fluid outlet. A check dart assembly, valve seat and piston assembly are retained within the central bore. The valve is moveable between open and closed positions in response to fluid flow into the fluid inlet of the valve.

International Classification:

B63H 2308

US Classification:

440 75

Abstract:

Ignition pulses derived from an engine ignition coil primary are fed to the input of an ignition interruption circuit that employs an integrated circuit timer. The state of the output terminal of the timer is governed by an RC time constant circuit and by trigger signals supplied by a trigger circuit in response to occurrence of each ignition pulse. The timer output is coupled to the gate of an SCR which when it receives gate current as a result of the timer output being in a high state becomes conductive and bypasses ignition pulses to ground to thereby lower engine rpm to a preset minimum in which case gate current is removed and at least enough ignition pulses are allowed to be unbypassed for keeping the engine running above stalling speed. The timer, in effect, compares the interval between pulses with its time constant. When the intervals are longer than the time constant period the timer output remains low and provides no gate current, but when the opposite condition exists gate current is supplied until the intervals between ignition pulses equal or exceed the time constant period.

International Classification:

B63H 506

US Classification:

440 1

Abstract:

Disclosed herein is a marine propulsion device and apparatus and methods for assisting transmission shifting thereof. The marine propulsion device includes an internal combustion engine and a reversing transmission having a pair of bevel gears and a clutch dog movable between a neutral position out of engagement with the bevel gears and forward and reverse drive positions in full engagement with one of the bevel gears. The marine propulsion device also includes a shift assistance arrangement included in a shift mechanism for axially moving the clutch dog between the neutral and drive positions, and which includes a load sensing lost motion shift lever arrangement having a first switch which is actuated when the resistance to axially moving the clutch dog into a drive position exceeds an upper limit. The shift assistance arrangement also includes an ignition interruption circuit responsive to actuation of the first switch for selectively interrupting the ignition of the internal combustion engine to reduce the engine torque transmitted to the bevel gears to effect relative angular displacement of the clutch dog and the bevel gears to thereby assist the shift mechanism in moving the clutch dog into and out of a drive position. The ignition interruption circuit includes a control circuit having a first timer for providing a plurality of successive timed cycles, each cycle including an ignition-kill interval and an ignition-on interval, and also having a second timer for establishing an overall cycle during which the first timer is operative, subject to the first switch.

Abstract:

Rams are provided in a blowout preventer to shear the drill string and seal the well bore should the need arise. Two shearing rams have cutting blades which shear the drill pipe. A seal member is mounted behind one of the cutting blades and is adapted to move into sealing position after shearing has occurred. Elastsomer flow into areas where there has been damage to the seal member is permitted by the design of the seal member.
