摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
