A running tool for deploying a secondary string into a wellbore with a primary tubing string includes a latch for selectively engaging a secondary string latching pin within the tool and means for activating the tool to disengage the latching pin from the tool.

Provided, in one aspect, is a ball seat release apparatus. The ball seat release apparatus, according to this embodiment, includes a shear sleeve having a recess pocket and a ball seat body slidingly engaged within the shear sleeve, the ball seat body configured to move from a first linear position to a second linear position. The ball seat body further includes a longitudinal fluid passageway, a ball seat located in the longitudinal fluid passageway, one or more first fluid bypass ports coupling the longitudinal fluid passageway and an exterior of the ball seat body, the one or more first fluid bypass ports located on a first side of the ball seat, and one or more second fluid bypass ports coupling the longitudinal fluid passageway and the exterior of the ball seat body, the one or more second fluid bypass ports located on a second opposing side of the ball seat.

Provided, in one aspect, is a whipstock. The whipstock may include a tubular having a longitudinal passageway extending along a length thereof, the tubular having a tapered face extending along at least a portion of the length; a support structure movably coupled to the tubular and extendable across the tapered face, wherein the support structure is operable to move from a first closed position closing the longitudinal passageway and a second open position exposing the longitudinal passageway; and a locking mechanism in the tubular for releasably holding the support structure in the first position.

A flow control valve (FCV) tool for a wellbore lined with a tubing string including a plurality of ports is presented. The FCV tool includes a body with a lower housing and an upper housing, the upper housing adapted to enable establishing a fluid path between the annulus of the wellbore and the plurality of ports. The lower housing and the upper housing form a pocket therebetween. The FCV valve also includes a unidirectional flow control valve designed to be received in the pocket and adapted to switch between a closed position and an open position and between the open position and the closed position based on a pressure differential between the annulus pressure and the internal pressure of the tubing string. The FCV tool enables multiple completion operations during the closed or open position of the valve.

A downhole release tools, systems, and methods are described. The tool configured to release a string in a wellbore includes: a cylindrical body with an uphole end defining a first set of internal threads and a downhole end defining a second set of internal threads; a sensor operable to measure strain in the cylindrical body, a magnetic field, or both; a release joint with an uphole end defining a first set of external threads and a frustoconical downhole end defining a second set of external threads, the release joint attached to the cylindrical body by engagement between the first set of external threads of the release joint and the second set of internal threads of the cylindrical body; safety pins rotationally fixing the release joint in position relative to the cylindrical body; and a drive system operable to rotate the release joint relative to the cylindrical body.

A bottom hole assembly (BHA) includes a top sub-assembly configured to couple to a downhole conveyance to move into a wellbore that includes completion components secured in the wellbore; a drill bit configured to drill out and remove a first portion of a subset of the completion components; and an expandable reamer including a cutting assembly and configured to adjust between a retracted position in which a diameter of the cutting assembly is less than a diameter of a bore through at least one of the completion components and an activated position in which the diameter of the cutting assembly is greater than the diameter of the bore. The expandable reamer is further configured to remove a second portion of the subset of the completion components in the activated position.

A setting tool for opening and dosing a sleeve inside a casing includes a body extending along a central longitudinal axis (X); a set of holding dogs located around the body; and a set of sleeve dogs located around the body. The set of sleeve dogs are configured to move along the central longitudinal axis (X) relative to the set of holding dogs.
