US Patent:

6364017, Apr 2, 2002
Filed:

Feb 22, 2000
Appl. No.:

09/510317
Inventors:

Gregg W. Stout - Montgomery TX
James T. Matte - Broussard LA
Assignee:

BJ Services Company - Houston TX
International Classification:

E21B 4304
US Classification:

166278, 166 51, 166 551, 166125, 166181, 166297
Abstract:

An improved single trip perforating and gravel pack system is provided which includes a tubing conveyed perforating assembly, a gravel pack completion assembly, and a retrievable service assembly. The retrievable service assembly includes a hydraulic setting tool and a crossover tool assembly. The hydraulic setting tool is less sensitive to hydraulic pressures generated by the detonation of the perforating guns. The hydraulic setting tool includes an annulus release mechanism, a preset lock assembly and a rotational lock assembly, all of which are mechanically actuated. The retrievable service assembly also includes a concentric check valve which improves well control and allows for reversing out excess slurry in the service assembly following completion of a gravel packing or frac packing operation.

US Patent:

56410190, Jun 24, 1997
Filed:

Dec 1, 1995
Appl. No.:

8/566456
Inventors:

Gregg W. Stout - Montgomery TX
James T. Matte - Broussard LA
Assignee:

BJ Services Company, U.S.A. - Houston TX
International Classification:

E21B 33128
US Classification:

166179
Abstract:

A swab-resistant packer is disclosed which prevents the packing element from expanding outwardly to cause swabbing during tripping of the apparatus in a subterranean well. Preferably, a metallic or other cable or cord is placed immediate and circumferentially around the exterior of the first and second ends of the packing element to prevent the packing element from moving outwardly away from the first, pre-set retracted position to thereby abate any tendency to swab.

US Patent:

55970400, Jan 28, 1997
Filed:

Aug 17, 1994
Appl. No.:

8/291979
Inventors:

Gregg W. Stout - Montgomery TX
James T. Matte - Broussard LA
Assignee:

Western Company of North America - Houston TX
International Classification:

E21B 4302
US Classification:

166 51
Abstract:

An apparatus is disclosed for fracing and gravel packing a subterranean well. The apparatus includes a packer and a liner assembly with a setting tool and crossover assembly. Abrasive wear in the wall of the crossover assembly is abated by providing for conversion of turbulent fluid flow of the fracing or gravel packing fluid into laminar flow immediate the opening within the crossover tool between the interior of the crossover tool and the exterior thereof. An isolator is also provided within the crossover such that when it is opened, a valve head is completely shielded and carried within the device whereby further cutting of the crossover tool wall by fluid flow is greatly abated.

US Patent:

51800101, Jan 19, 1993
Filed:

Jul 26, 1991
Appl. No.:

7/736389
Inventors:

Gregg W. Stout - Montgomery TX
James T. Matte - Broussard LA
Assignee:

The Western Company of North America - Houston TX
International Classification:

E21B 2304
US Classification:

166212
Abstract:

A multiple acting lock is provided which prevents premature setting of the packer of a gravel pack tool by the setting piston of a setting tool. The lock comprises a locking cylinder which when in the locked position rotationally locks the setting tool with the gravel pack tool thereby allowing rotation of the tool during tripping to facilitate working the tool past tight spots. The lock also longitudinally locks the setting sleeve of the gravel pack tool to prevent premature setting of the packer of the gravel pack tool. The locking mechanism of the setting sleeve comprises keys located in keyholes and a sleeve inside the setting sleeve which protrude and engage with the setting sleeve. The locking cylinder when in a locked position covers the inside of the keyholes retaining the keys in engagement with the setting sleeve. When the locking cylinder is hydraulically moved to the unlocked position the keys slide inward out of the keyholes and out of engagement with the setting sleeve.

US Patent:

59312297, Aug 3, 1999
Filed:

May 13, 1997
Appl. No.:

8/854933
Inventors:

Douglas J. Lehr - Woodlands TX
James T. Matte - Broussard LA
Assignee:

BJ Services Company - Houston TX
International Classification:

E21B 4304
US Classification:

166278
Abstract:

A through tubing gravel pack assembly which is capable of being run on a coiled tubing string inside existing tubing for repairing a preexisting gravel pack. The through tubing gravel pack system comprises a hydraulically releasable running tool and service assembly, a hydraulically set through tubing packer assembly and a crossover sleeve and sliding sleeve valve assembly. The gravel pack assembly is adapted to be shiftable between a circulating mode and a squeeze mode for conducting a circulating gravel pack and/or a squeeze gravel pack without the necessity of having to trip the assembly out of the borehole.
