6464007, Oct 15, 2002

Filed:

Aug 22, 2000

Appl. No.:

09/642563

Inventors:

Lloyd G. Jones - Granbury TX

Assignee:

ExxonMobil Oil Corporation - Irving TX

International Classification:

E21B 4304

US Classification:

166279, 166235

Abstract:

A method and well tool for using a low-viscosity slurry to gravel pack a completion interval. The well tool is comprised of a screen and at least one alternate flowpath which is initially closed to flow by a valve means. Once a sand bridge is formed in the completion interval, the pressure of the pumped slurry increases which, in turn, opens the valve means to allow flow through the alternate flowpath. Preferably, a plurality of flowpaths of different lengths are provided, all of which include valve means which are adapted to open at different pressures.

International Classification:

E21B 4304

US Classification:

166278, 166 51, 166276

Abstract:

A well screen and method for gravel packing a wellbore interval wherein a low-viscosity slurry can be used to distribute the gravel. A well screen having a plurality of spaced intermediate manifolds is lowered into the interval and slurry is pumped down the well and into the first manifold. Each intermediate manifold has an upper and a lower perforated shunt tube in fluid communication therewith which, in turn, distribute slurry in both an upward and downward direction substantially simultaneously. The slurry exits the respective tubes into spaced zones within the completion interval. By overlapping the exit openings of respective lower and upper shunt tubes of adjacent manifolds, slurry will be delivered to across the entire completion interval.

Abstract:

Method and apparatus for fracturing different levels of a completion interval in a well. A workstring lowers a fracturing string which, in turn, is comprised of a base pipe which is blank except for perforated sections spaced along its length. Screen may be provided over said sections to block the flow of sand into the base pipe. An alternate flow path (e. g. shunt tubes) extends along the base pipe and has one or more outlets spaced along its length. A slurry is flowed into the annulus surrounding the fracturing string. As liquid is lost from the slurry, sand from the slurry will form bridges at said perforated sections thereby isolating portions of the annulus. Slurry then flows through the shunts tube(s) and out into the isolated portions to fracture the different levels in the completion interval.

International Classification:

US Classification:

166281, 166189, 166192, 166236

Abstract:

A method for the treatment of a subterranean formation penetrated by a well in which, first and second flow paths are established from the wellhead into the vicinity of the formation. A plugging fluid comprising a suspension of a particulate plugging agent in a carrier liquid is circulated into the first flow path and into contact with the wall of the well within the subterranean formation. The carrier liquid is separated from the particulate plugging agent by circulating the carrier liquid through a set of openings leading to the second flow path, which are dimensioned to allow the passage of the carrier liquid while retaining the particulate plugging agent in contact with the set of openings. The circulation of the plugging fluid continues until the particulate plugging agent accumulates to form a bridge packing within the well. Subsequent to establishing the bridge packing, a treating fluid is introduced into the well through the first flow path and in contact with the surface of the formation in the well adjacent to the bridge packing.

International Classification:

F16K 13/08

US Classification:

137312, 137 67, 137 6811, 251 74, 122504, 122507

Abstract:

An automatic system which includes a tripper unit for actuating a device (e. g. valve-closing actuator) upon contact with water. Basically, the tripper unit is comprised of a housing having a cartridge therein which, in turn, is wrapped with an adsorbent paper which prevents a plunger from moving downward. When a leak occurs, water will flow into the housing and into contact with the absorbent paper which will quickly disintegrate allowing the plunger to move downward to thereby actuate the valve actuator to close the valve. The tripper unit may be a separate component of the system or both the tripper unit and the valve actuator can be incorporated into a single unit.

Abstract:

An automatic flow shut-off unit for shutting off water to an appliance (e. g. commode) when a leak or overflow occurs. The unit includes an outer housing having a ball valve mounted thereon wherein the valve is connected between the water supply and the appliance. A tripper unit is mounted in the outer housing and has a plunger therein. The valve is connected to the plunger by a length of actuation material (e. g. flexible cable). A compression spring is positioned in the tripper unit to normally bias the plunger downwards. A cartridge having a water reactive material (e. g. commercially-available toilet paper) thereon is removably mounted in the outer housing wherein the water reactive material when dry supports the plunger in a cocked position but which will quickly weaken and disintegrate upon contact with water.
