摘要： A method for pulling casing includes disposing a casing modification and pulling tool having an element therein that includes a profile, causing the element to move radially outwardly into contact with a casing disposed radially outwardly of the tool, deforming the casing with the element, applying a load to the casing, and failing the casing at the deformation. A system for pulling casing includes a casing modification tool having an element radially displaceable into a casing disposed radially outwardly thereof, the element configured to deform the casing, a casing spear operably connected to the casing modification tool, the spear configured to apply a load to the casing to fail the casing at the deformation. A borehole system includes a borehole in a subsurface formation, a casing disposed in the borehole, and a casing modification and pulling tool disposed in the casing.

摘要： A casing cutting system including a tubular having a first end, a second end, an inner surface defining a passage extending between the first end and the second end, an outer surface, and a window extending through the inner surface and the outer surface. A deployment member is mounted in the passage. A plurality of cutter blades is arranged in the passage at the window. The plurality of cutter blades is pivotally mounted to the deployment member. A sensor is operatively coupled to the deployment member. The sensor is operable sense an amount of travel of each of the plurality of cutters.

摘要： A cutter for a downhole cutting tool is disclosed. The cutter includes a cutter body having a cutting face, a peripheral sidewall flank, and a base. The base has a recessed channel that extends inwardly from the peripheral sidewall flank and provides an inlet opening therein. A downhole cutting tool employing the cutter is also disclosed. The cutting tool includes a tool body having a cutter face. The tool also includes a cutter body having a cutting face, a peripheral sidewall flank, and a base, the base having a recessed channel that extends inwardly from the peripheral sidewall flank and provides an inlet opening therein. The tool also includes a braze joint between the base and the bonding surface.
