摘要： The operational position of a sliding sleeve is detected using an electrode-type logging tool. The logging tool generates a baseline log of the sliding sleeve in a non-actuated position, and a response log of the sliding sleeve in an actuated position. The baseline and response logs are then compared in order to determine the operational position of the sliding sleeve.

摘要： A system for fracturing a hydrocarbon bearing formation includes a valve including a tubular housing having a bore therethrough and one or more flow ports formed through a wall thereof. One or more locator tags are embedded in the housing, and a sleeve is disposed in the housing and movable relative thereto between an open and a closed position. The system also includes a shifting tool comprising a shifter movable between an extended position and a retracted position and operable to engage the valve sleeve. The shifting tool includes a lock that keeps the shifter extended in the locked position and allows the shifter to retract in the unlocked position. The shifting tool also includes an antenna for detecting the locator tags, and an electronics package in communication with the antenna and the actuator for operating the actuator in response to detection of the locator tags.

摘要： A downhole bypass valve utilizes a stationary sleeve defining an interior ball-seat. When a dropped ball is seated, fluid differential pressure is diverted to an annular area adjacent a first sliding sleeve. The sleeve slides in response to the pressure differential upon shearing of a shear pin, or similar, and opens ports to the wellbore annulus. Treatment or maintenance operations can then occur through the ports, which can be fitted with nozzles. A second sliding sleeve, independent from the first, is operated in response to dropping a second ball into the device. The second ball diverts fluid differential pressure to an annular area adjacent the second sleeve and movement occurs when a shear pin shears. The second sleeve covers the ports to the wellbore annulus and closes the valve. After a sliding sleeve shifts, pressure across the sleeve is equalized, allowing reverse flow without risk of accidental sleeve actuation.

摘要： A ported completion and method for use in fracturing multi-zone wells. A casing assembly having a plurality of casing lengths and one or more collars positioned so as to couple together the casing lengths. The collars may be a tubular body having an inner flow path, one or more fracture ports configured to provide fluid communication between an outer surface of the collar and the inner flow path, one or more valve holes intersecting the fracture ports, one or more valve vent holes positioned to provide fluid communication between the valve holes and the inner flow path, and one or more valves positioned in the valve holes for opening and closing the fracture ports. The valves are configured to open when a pressure differential is created between the fracture ports and the valve vent holes. The valve vent hole may be an annulus around the perimeter of the tubular body.

摘要： A downhole tool comprises a hollow body having a wall and a port in the wall, and a closing sleeve movable relative to the body to open and close the port. A seal is provided between the body and the sleeve and is configured to hold differential pressure. An isolation member may be deployed in the tool to isolate the seal from differential pressure and close the port. The isolation member may be deployed following initiation of a tool activation process, a successful outcome of the process being translating the closing sleeve and closing the port, and positioning the seal to hold a differential pressure. If it is detected that the outcome has not been achieved, the isolation member is deployed to isolate the seal from differential pressure and close the port.

摘要： A setting tool for hanging a tubular string includes: a mandrel having an upper portion and a lower portion for extending into the tubular string; a housing connected to the mandrel upper portion; and a bonnet. The bonnet is: for receiving an upper end of the tubular string, disposed along the mandrel, and linked to the housing. The setting tool further includes: an actuator for stroking the bonnet relative to the mandrel and the housing, thereby setting a hanger of the tubular string; an electronics package in communication with the actuator for operating the actuator in response to receiving a command signal; and a latch. The latch is: connected to the mandrel lower portion, operable between an extended position and a retracted position, for being restrained in the retracted position by being disposed in the tubular string, and extendable by being removed from the tubular string.

摘要： A down-hole treatment tool including a tool body having a bore therethrough, a treatment port orifice disposed on the body, a sliding sleeve within the bore of the body. A constant-volume annular chamber, in isolation from the inner bore and the environment outside the body, provides a debris-free environment for locking the sleeve. A dissolvable treatment port cover provides protection of the treatment port until operation of the treatment port is needed. The treatment port cover and lubrication ports enable lubrication of the sleeve and inner bore of the body without risk of contamination by debris.

摘要： An apparatus and method for providing a time delay in injection of pressured fluid into a geologic formation. In one aspect the invention is a toe valve activated by fluid pressure that opens ports after a predetermined time interval to allow fluid to pass from a well casing to a formation. The controlled time delay enables casing integrity testing before fluid is passed through the ports. This time delay also allows multiple valves to be used in the same well casing and provide a focused jetting action to better penetrate a concrete casing lining.
