摘要： A wellhead latch assembly may include one or more latches for attaching to a wellhead and allowing removal of the wellhead during a well abandonment process. The wellhead latch assembly may include an inner core coupled to the latches, and an outer sleeve for selectively latching and unlatching the latches to the wellhead. The inner core may abut the wellhead and can include a groove having circumferential and/or longitudinal features. The outer sleeve may include a pin which travels within the groove and a set of cut-outs for alignment with the latches. When the cut-outs align with the latches, the latches may expand radially outward and disengage the wellhead. As the outer sleeve moves axially or rotationally relative to the inner core, the latches may fall out of alignment with the cut-outs and move radially inwardly to engage or capture the wellhead.

摘要： A section mill for removing a portion of a casing in a wellbore. The section mill may include a body having a first end portion, a second end portion, and a bore formed axially therethrough. A plurality of blades may be coupled to the body. Each of the blades may have a first end portion and a second end portion. The first end portion of each blade may be coupled to the body via a hinge pin, and the second end portion of each blade may have a cutting surface formed thereon. A seat may be formed within the bore. The blades may be adapted to actuate from an inactive position to an active position in response to an impediment forming a seal against the seat.

摘要： A downhole cutting tool includes a tool body and a plurality of cutter knife sets, each of the plurality of cutter knife sets configured to extend outwardly to separately perform a pipe cutting operation. A first cutter knife set has a diameter in an extended position larger than a diameter in an extended position of a second cutter knife set. A method includes running the downhole cutting tool into a wellbore, deploying the first set of expandable cutting arms to an extended position and engaging the extended expandable cutting arms with a first work piece, rotating the downhole cutting tool and cutting the first work piece, deploying the second set of expandable cutting arms during a single trip into the wellbore to an extended position and engaging the extended expandable cutting arms with a second work piece, and rotating the downhole cutting tool and cutting the second work piece.

摘要： A spearing device for use in removing casing is disclosed. The spearing device includes: a top sub; a bottom sub; a mandrel, coupled to the top and bottom subs, having an outer corrugated surface; a grapple having a correspondingly corrugated inner surface and an outer surface including wickers for engaging an interior surface of the casing; a piston disposed within the mandrel and operatively coupled to the grapple; and a spring operative with the piston and biasing the grapple toward a collapsed position. The grapple: (i) axially and rotationally moves along the corrugated outer surface of the mandrel and (ii) expands and collapses responsive to axial movement relative to the mandrel. Responsive to increases in hydraulic pressure, the piston compresses the spring and axially moves and expands the grapple. Responsive to subsequent decreases in hydraulic pressure, the spring decompresses and axially moves and collapses the grapple.

摘要： A spearing device for removing casing from wellbore includes a top sub, a bottom sub, and a mandrel coupled to the top and bottom subs. The device includes a grapple having a corrugated inner surface corresponding to a corrugated portion of the mandrel and an outer surface including wickers for engaging an interior surface of the casing. A piston is disposed within the mandrel and operatively coupled to the grapple. A spring operates with the piston and biases the grapple toward a collapsed position. The grapple axially and rotationally moves along the corrugated outer surface of the mandrel. The grapple expands and collapses in response to axial movement relative to the mandrel. The piston compresses the spring and axially moves and expands the grapple in response to increases in hydraulic pressure. In response to subsequent decreases in hydraulic pressure, the spring decompresses and axially moves and collapses the grapple.
