A downhole device and a method of performing an operation in a borehole. The downhole device includes an outer sleeve defining a bore therethrough, an inner sleeve disposed within the bore and axially movable with respect to the outer sleeve between a first position and a second position, the inner sleeve defining a flow passage, and a seat member in the flow passage for seating a ball when the inner sleeve is at the first position. A ball is seated at the seat member. A fluid pressure on the ball moves the inner sleeve from the first position to the second position, moves the seat member radially outward out of the flow passage when the inner sleeve is at the second position, and pushes the ball out of the flow passage.

Shifting sleeve with extrudable ball and dog

An assembly and a method of performing an operation in a borehole. The assembly includes a plug, and a retrieving head rigidly coupled to the plug in a locked configuration. The retrieving head includes a lock disposed therein comprising a housing, a mandrel, and a ball seat. The ball seat is secured to the housing at a first seat location when the assembly is in the locked configuration. The assembly is conveyed assembly in the borehole. A ball is dropped through the assembly to seat at the ball seat. A fluid pressure created at the ball moves the ball seat to a second seat location within the housing to place the assembly in an unlocked configuration. The mandrel is shifted to allow the retrieving head to move axially in the unlocked configuration.

Extrusion ball actuated telescoping lock mechanism

A clutch mechanism of a downhole assembly and a method of operating the assembly in a borehole. The clutch mechanism includes a plug including a mandrel and a wall-engaging component, a sub of a ball valve, the sub coupled to the mandrel, a torque lock nut of the ball valve, the torque nut coupled to the wall-engaging component, and a clutch of the ball valve. The clutch is moved axially against the torque lock nut to engage the torque lock nut to the sub. A torque is applied on the clutch to rotate the sub of the ball valve via transmission of the torque from the clutch to the ball valve via the torque nut. Application of the torque against the sub actuates the ball valve.

Torque mechanism for bridge plug

A method of performing a well bore operation in a well bore includes connecting a window mill to a whipstock connector forming a tubular section, supporting a tool below the whipstock connector, running the window mill, the whipstock connector, and the tool into the well bore, and axially loading the tool to perform the well bore operation.

Window mill and whipstock connector for a resource exploration and recovery system

A single-trip cut and pull system for a wellbore including a cutter, a power section, and an anchor selectively actuable independently of the power section; a method for cutting and pulling casing in a single run including running a cut and pull system on a string to a target depth, rotating a cutter of the cut and pull system to cut a casing section, and actuating an anchor of the cut and pull system after cutting the casing section; and a method for cutting and pulling casing in a single run including running a cut and pull system on a string to a target depth, rotating a cutter of the cut and pull system by rotating the string to cut a casing section, and pulling the cut casing in the single run.

Downhole pulling tool with selective anchor actuation

A window cutting system includes a window mill having a body including a connector member, a tip portion, and a plurality of blades arranged between the connector member and the tip portion. Each of the plurality of blades supports a plurality of cutting elements. A lug pocket is formed in at least one of the plurality of blades adjacent the plurality of cutting elements. A whipstock connector detachably coupled to the window mill. The whipstock connector including an outer surface and an inner surface, and at least one lug projecting radially inwardly from the inner surface. The at least one lug is selectively received by the lug pocket to connect the whipstock connector to the window mill.

A BHA features an MWD tool connected to a running tool supporting a whipstock that is connected to an open hole anchor. The anchor is flow set and after the anchor is set the running tool collets release from the whipstock to allow cement to be pumped through the anchor to hold the set position. The collets are released from the whipstock also with flow and after the anchor has been set. One way is to use nozzles in series. Another is to run in with a ball on the anchor seat, set the anchor and blow out the ball seat so flow can again be used to release the running tool collets. Another is suspending a ball above the anchor seat, releasing the ball with pressure cycle, open another flow passage to allow collet release of the whipstock. Finally, pressure can be used to release the running tool collets.

Hydraulically set open hole whipstock

A one trip bottom hole assembly allows setting and testing a plug and release from the plug. Cement can be pumped onto the plug, after the BHA is raised, to an extent to meet local regulatory requirements. The cutter spear combination can be activated with pressure built on a second dropped ball larger than the first ball to release the blades for extension with fluid circulation. The circulation path through the spear is opened using pipe manipulation during the spear setting sequence. The cuttings from severing the tubular fall onto the cement. The spear is set with string manipulation as the drill string rotates the blades while maintaining the string under tension. The spear can be released and repositioned for the top of the string to facilitate removal and disassembly at the surface. All the above described operations are accomplished with a single trip into the hole.

Method of wellbore isolation with cutting and pulling a string in a single trip

A valve for subterranean whipstock service has a side port and a through passage with a biased movable sleeve to shift between circulation mode into the annulus and flow through mode for setting an anchor and then feeding window mill nozzles. The valve is run in when in circulation mode to allow operation of a measurement while drilling device. When the whipstock is properly oriented the pressure is increased to break a shear pin to allow a spring to bias the sleeve to the flow through position. The shifting of the sleeve opens a bypass passage around the restriction orifice that was first used to build pressure to break the shear pins that let the sleeve move under spring bias. As a result the spring can hold the sleeve in position despite high flow rates needed to remove cuttings from the mill as the window is opened.
