Abstract: A shutoff valve device for permitting and preventing fluid flow in a production string. In one embodiments, the shutoff valve device comprising: a body comprising a borehole, wherein the body is a top sub coupled to a bottom sub via a threaded fastener; a flow tube disposed within the body's borehole and capable of axial movement within the body's borehole, comprising a flow tube borehole; a bi-directional actuator attached to a bottom opening of the flow tube, comprising flexible flaps; and a flapper valve disposed within the body's borehole, wherein the flapper valve is hingedly coupled to a top surface of the bottom sub and capable of moving between a fully opened and fully closed position.

Abstract: A frac plug is provided. The frac plug may include a plug body, a slip, a sealing element, and a compression ring. The plug body may have a first end portion and a second end portion. The slip may be circumferentially disposed about the plug body and configured to expand and couple the frac plug to a tubular section. The sealing element may be circumferentially disposed about the plug body and configured to create a seal between the plug body and an inner surface of the tubular section. The compression ring may be circumferentially disposed about the plug body proximate to the first end portion and abut the sealing element. The compression ring may be configured to expand when shifted along the plug body to compress the sealing element and retain the sealing element in a compressed position.

Abstract: A system of sliding valves wherein the inserts of multiple sliding valves may be shifted to an open position using a single shifting ball. Each individual sliding valve has a movable insert that, depending upon the position of the insert within the sliding valve, may either block, permit fluid to radially flow between the interior and exterior of the sliding valve at a first rate, or permit fluid to radially flow between the interior and exterior of the sliding valve at some different second rate.

Each individual sliding valve has a movable insert that, depending upon the position of the insert within the sliding valve, may either block or permit fluid to radially flow between the interior and exterior of the sliding valve. The insert has a profile about the interior of the movable insert allowing a shifting tool to connect to and move the insert so that fluid may be prevented from entering the interior portion of the sliding sleeve.

Abstract: A downhole sleeve has an insert movable in the sleeve's bore from a closed condition to an opened condition when a ball dropped in the bore engages an indexing seat in the sliding sleeve. In the closed condition, the insert prevents communication between the bore and the sleeve's port, while the insert in the opened condition permits communication between the bore and port. Keys of a seat extend into the bore to engage the ball and to move the insert open. After opening, the keys retract so the ball can pass through the sleeve to another cluster sleeve or to an isolation sleeve of an assembly. Insets or buttons disposed in the sleeve's port temporarily maintain fluid pressure in the sleeve's bore so that a cluster of sleeves can be opened before treatment fluid dislodges the button to treat the surrounding formation through the open port.

Abstract: A downhole sleeve has a sliding sleeve movable in a bore of the sleeve's housing. The sliding sleeve is movable from a closed condition to an opened condition when a ball is dropped in the sleeve's bore and engages an indexing seat in the sliding sleeve. The sliding sleeve in the closed condition prevents communication between the bore and the port, and the sleeve in the opened condition permits communication between the bore and the port. In the closed condition, keys of the seat extend into the bore to engage the ball and to move the sliding sleeve open. In the opened condition, the keys of the seat retract from the bore so the ball can pass through the sleeve to another cluster sleeve or to another isolation sleeve of an assembly.
