Abstract: A method of separating a downhole tubular includes running a tool into a wellbore to a predetermined location on a work string and actuating flow actuated slips. The method also includes maintaining slips in a set position by providing a first upward force on the work string. The method further includes rotating the work string to separate an upper portion of the tubular from a lower portion using a cutter assembly disposed on the work string below the slips and pulling the upper portion of the tubing and the tool from the wellbore.

Abstract: A method and apparatus for a locking system for a downhole tool. The locking system includes a first portion having a plurality of displaceable members, a second portion disposed around the first portion; a locked position wherein axial movement between the members is prevented; and an unlocked position wherein axial movement between the members is permitted.

Abstract: A sidetrack assembly for forming a lateral wellbore includes a cutting device having a body having a passage, and a mill head configured to connect to the body so that an interior of the mill head and the body form a pressure chamber in fluid communication with the outlet passage. The mill head includes a first port in fluid communication with the pressure chamber, a second port in fluid communication with the pressure chamber, and a blade arranged on a face of the mill head. A whipstock connected to the cutting device includes a tubing having a first end removably inserted in the first port and the passage and a second end connectable to a downhole tool, an inclined surface for guiding the mill at a non-zero angle relative to a central axis of an existing wellbore, and an attachment section removably connecting the cutting device and the whipstock.

Abstract: A tool for cutting a tubular includes a housing, a first blade having a first cutting surface, and a second blade having a second cutting surface. The first blade and the second blade are configured to move between an extended position and a retracted position. The first blade and the second blade are disposed in the housing in the retracted position. The first cutting surface and the second cutting surface overlap in the retracted position. In another embodiment, a tool for cutting a tubular in a wellbore, includes a housing having a longitudinal axis; a pin connected to the housing and disposed on a first side of the longitudinal axis; and a blade including a cutting surface, the blade configured to move between an extended position and a retracted position about the pin, wherein the cutting surface is disposed at least in part on a second side of the longitudinal axis in the retracted position.

Abstract: A stabilizer for passing through a restriction includes a tubular body having a bore therethrough; a rigid blade disposed on the tubular body; and a deformable blade disposed on the tubular body, wherein the deformable blade includes a geometric profile configured to preferentially bend the deformable blade in one direction when the deformable blade encounters the restriction, and wherein the deformable blade has a height greater than a height of the rigid blade. In one example, the deformable blade is offset from a radial axis.
