摘要： A stage tool for wellbore annular cementing may be opened for cementing by hydraulic actuation of a sliding sleeve valve from over a fluid port. After sufficient cement has been introduced, the stage tool fluid port can be closed by compressing two telescopically arranged parts of its tubular body to further overlap each other and overlie the fluid port. This permits the stage tool to be closed without employing a plug.

摘要： A dual liner assembly for a multilateral fracking system, comprises a junction support liner adapted to be installed in a lateral wellbore at a junction with a main wellbore; an inner liner with an upper portion and a lower portion, the inner liner being positioned inside the junction support liner and extending beyond the junction support liner within the main wellbore and within the lateral wellbore when the assembly is installed; and a cut and release connector adapted to join the inner liner and the junction support liner and to enable detaching of the upper portion of the inner liner from the assembly. A method of multilateral fracking is also described.

摘要： A method for wellbore treatment includes running a liner into a wellbore, the liner including a wall, an inner bore defined by the wall, a first port through the wall, a second port though the wall spaced axially from the first port, a first removable closure for the first port and a second removable closure for the second port; positioning the liner in an open hole section of the wellbore to create an annulus between the liner and a portion of the wellbore wall and with the second port downhole of the first port; inserting a treatment string assembly into the liner, the treatment string assembly including a tubing string and an annular seal about the tubing string and being insertable into the inner bore of the liner; setting the annular seal to create a seal between the tubing string and the liner downhole of the second port; and while the first port is closed to fluid flow therethrough, pumping wellbore treatment fluid into an annular area between the tubing string and the liner such that the fluid passes through the second port and into the annulus to treat the open hole section of the wellbore adjacent the second port. The treatment string assembly may further include a port-opening tool and a fluid communication port permitting fluid communication between the tubing string outer surface and a fluid conduit through the tubing string adjacent an upper side of the annular seal.

摘要： An apparatus for fluid treatment of a borehole, the apparatus allowing initial outflow injection of fluids into a wellbore in which it is installed and then is actuable to allow fluid inflow control. The apparatus includes: a tubular body, a first port and a second port opened through the wall of the tubular body, the second port having a fluid inflow controller positioned to control the flow of fluid into the tubular body through the port, a sliding sleeve valve in the tubular body moveable from (i) a first position closing the first port and the second port to (ii) a second position closing the second port and permitting fluid flow through the first port and to (iii) a third position closing the first port and permitting fluid flow through the second port; a sleeve actuator for actuating the sliding sleeve valve to move from the first position to the second position in response to a force applied thereto; a releasable lock for locking the sliding sleeve valve in the first position and selected to maintain the sliding sleeve valve in the first position after the force is removed; and a lock release mechanism configured to actuate the releasable lock to release the sliding sleeve valve to move into the third position.

摘要： A stage tool comprises a body with a tubular wall, defining an outer surface and an inner surface. Fluid ports, such as cement circulation ports, extend through the tubular wall. The stage tool further comprises a primary closing sleeve. The primary closing sleeve may be movable along the outer surface of the tubular wall for closing the ports when the treatment of the wellbore stage ends. A secondary closing sleeve may be movable along the inner surface of the tubular wall for closing the port in case of failure of the primary closing sleeve or for redundancy. The primary closing sleeve may be actuated by an internal member joined to the primary closing sleeve by a crosslink and movable on the inner surface. The internal member and the secondary closing sleeve may move along different surfaces on the internal wall to avoid interference.
