US Patent:

58788182, Mar 9, 1999

Filed:

May 28, 1998

Appl. No.:

/085872

Inventors:

Joseph V. Hebert - Tomball TX
John E. Campbell - Houston TX
Thomas F. Bailey - Houston TX

Assignee:

Smith International, Inc. - Houston TX

International Classification:

E21B 708

US Classification:

166382

Abstract:

A mechanical set anchor wherein a plunger extending from a base end of an anchor body activates a pin type trigger which releases a spring utilized to set multiple slips extending from the body of the anchor. Continued downward compressive forces fully sets the slips into the borehole pipe casing. The slips are maintained in their fully set position by a locking nut. The slips are further set into the pipe casing after slips are released from the anchor body. The anchor is mechanically released by an upward pull under tension of sufficient strength to shear release pins that release the compressed spring fully retracting the slips within the anchor body so that the anchor may be tripped from the borehole without interference from the previously engaged slips.

Assignee:

Drilex Systems, Inc. - Houston TX

International Classification:

E21B 2902
E21B 2912

US Classification:

166 551

Abstract:

A detonation assembly for an explosive wellhead severing system which employs a battery pack lowerable through a drill string to engage and power the detonation assembly positioned within the well bore. The lowerable unit includes a biased shutter which seals the contacts from discharge of the battery pack by the surrounding fluids. The shuttered unit is lowered into contact with the receiving unit to arm the detonation assembly. Until the power unit is lowered into engagement, the severing system is not armed. In case of malfunction or misfire, the power unit can be retrieved to disarm the detonator assembly. The entire assembly is housed within the drill string to isolate the critical elements from the surrounding environment.

Appl. No.:

7/925718

Inventors:

Joseph V. Hebert - Tomball TX

Assignee:

MASX Energy Services Group, Inc. - Houston TX

International Classification:

E21B 2900

US Classification:

166298

Abstract:

A wellhead severing system for detonating a liquid explosive charge and subsequent removal of the wellhead from the sea floor. The explosive severing system includes a charge container holding a liquid explosive and a contractable bladder in fluid communication with the charge container to compensate for pressure and temperature variations as the system is lowered to the wellhead in the sea floor. Liquid explosive from the bladder flows into the charge container maintaining a constant volume of uncontaminated explosive around the detonators. The severing system is lowered into the wellhead on a running string and detonated through high voltage wires extending to a connector or the surface.

International Classification:

E21B 708

US Classification:

166 557

Abstract:

A two trip sidetrack casing milling apparatus for elongating and enlarging a previously formed window in a cased borehole in preparation for a subsequent sidetracking drilling operation is disclosed. The apparatus consists of three mills on a shaft, a first window mill is secured to an end of a shaft. The first window mill forms a diameter larger than a diameter of a subsequent sidetracking drill bit that is passed through the window. A second pilot mill is secured to the shaft and strategically positioned above the first window mill. The second pilot mill forms a diameter that is less than the diameter of the first window mill. A third watermelon mill is secured to the shaft and strategically positioned above the second pilot mill. The third watermelon mill forms a diameter that is at least the same diameter as the first window mill. The second, smaller in diameter pilot mill serves to move toward the window thereby straightening the shaft while further cutting a portion of the casing surrounding the window thus assuring a more stable and accurate sidetrack direction.
