    摘要: An expandable drilling apparatus is deployed upon a distal end of a drillstring and includes a cutting head and a substantially tubular main body adjacent the cutting head providing a plurality of axial recesses configured to receive arm assemblies configured to translate between a retracted and an extended position. A flow switch actuates the arm assemblies when a drilling fluid pressure exceeds an activation value and the drilling apparatus includes a biasing member to reset the arm assemblies when the drilling fluid pressure falls below a reset value.

    摘要: A downhole stabilizer includes a radial expansion assembly deployed about, and configured to rotate substantially freely with respect to, a tool mandrel. The expansion assembly preferably includes at least one stabilizer block configured to extend radially outward from the mandrel into contact with a wellbore casing string. When deployed between uphole and downhole cones, the stabilizer block preferably includes a plurality of angled splines configured to engage corresponding splines disposed on the cones. Relative axial motion between the stabilizer block and the cones causes a corresponding radial extension or retraction of the block.

    摘要: A dual string section milling tool includes a cutting block deployed in an axial recess in a tool body. The cutting block is configured to extend radially outward from and retract radially inward towards the tool body. The cutting block is further configured to remove a cement layer in a wellbore. The dual string section milling tool further includes a milling blade deployed in an axially slot disposed in the cutting block. The milling blade is configured to extend radially outward from and inwards towards the cutting block. The milling blade is further configured to cut and mill a section of casing string. The dual string section milling tool may be further configured to simultaneously remove cement and mill a wellbore tubular.

    摘要: A casing patch and methods for using same are provided. The patch can include a hollow, substantially tubular body. An opening can be formed in the body. A tapered slot can be formed in the body below the opening. A width of the tapered slot proximate the opening can be greater than the width of the tapered slot distal the opening. The tapered slot can be adapted to receive a tapered wedge and expand radially outward as the tapered wedge slides within the tapered slot and away from the opening.
