Patent number: 9725977Abstract: Cutter blades extend and stay extended as long as pressure on a piston is continued. The blades either open fully in open hole or cut through the wall of a tubular and then mill in an uphole direction to take out a piece of the tubular. The piston that held out the blades when pressure was applied is acted on by a return bias when the pressure is removed so that the blades can retract and the tool removed through the cut tubular. As a backup a plug can be dropped to obstruct a through passage in the piston so that pressure from the surface can be used to force the piston back to retract the blades. Continued drilling operations or the cut and milled portion can be then blocked off such as with cement for a plug and abandonment of the well.Type: GrantFiled: October 2, 2014Date of Patent: August 8, 2017Assignee: Baker Hughes IncorporatedInventors: Mary L. Laird, Robbie B. Colbert

Patent number: 9574417Abstract: A bottom hole assembly for engaging and removing an object within a wellbore comprises a cutting tool at a lower end. Continued engagement of the cutting tool with the object is facilitated by an axial compression device disposed within the bottom hole assembly below the anchor of the bottom hole assembly. The axial compression device comprises a compressed position and an expanded or extended position. As the object is being cut or abraded, the axial compression device moves from the compressed position toward the expanded position so that a continued downward force is transferred to the object by the bottom hole assembly.Type: GrantFiled: June 5, 2013Date of Patent: February 21, 2017Assignee: Baker Hughes IncorporatedInventors: Mary L. Laird, Robbie B. Colbert, David W. Coleman

Patent number: 9366101Abstract: A cutting and pulling tool has a piston responsive to flow therethrough with an orifice to create backpressure to drive the piston uphole to rotate the blades outwardly such as in an expanded section of tubular below a transition from a smaller tubular dimension. The extended cutters are pulled to the transition and an overpull determines that the desired location has been reached. The overpull force is removed and fluid flow and rotation is commenced to cut. The blades extend to a position perpendicular to the tool axis so that they are supported off a radial housing surface as the weight of the cut string above is supported on the blades. The string is pulled up and supported with slips on a rig floor at which point weight is slacked off and a plug is landed in the top of the piston to push it down to remove the tool.Type: GrantFiled: October 4, 2012Date of Patent: June 14, 2016Assignee: Baker Hughes IncorporatedInventors: Robbie B. Colbert, Randall L. Hebert, Joshua C. Joerg, Mary L. Laird

Patent number: 8915298Abstract: A tool is run in with a bottom hole assembly that includes a seal and support within the tubing where a fish is to be milled. A ported sub allows pressurized fluid pumped from the surface to enter the bottom hole assembly above the sealed support location and to be directed to set an anchor and to a fluid driven motor such as a progressive cavity motor that is in turn connected milling tool at the rotor of the progressive cavity motor. The fluid exiting the stator goes through a debris removal device and can return to the surface through an annulus around the production tubing. A telescoping joint allows the mill to axially progress with a force applied to the fish generated by a tractor or a stack of Belleville washers.Type: GrantFiled: August 16, 2012Date of Patent: December 23, 2014Assignee: Baker Hughes IncorporatedInventors: Mary L.

A ported sub allows pressurized fluid pumped from the surface to enter the bottom hole assembly above the sealed support location and to be directed to set an anchor and to a fluid driven motor such as a progressive cavity motor that is in turn connected to the tubing cutter at the rotor of the progressive cavity motor. The rotation of the cutter with its blades extended cuts the tubular as the fluid exiting the stator goes to the lower end of the tubing being cut and can return to the surface through an annulus around the tubing to be cut. Other configurations such as cutting casing or cutting casing through tubing are also envisioned.Type: GrantFiled: June 7, 2010Date of Patent: March 26, 2013Assignee: Baker Hughes IncorporatedInventors: Mary L.

Patent number: 7591314Abstract: Methods and devices for sensing operating conditions associated with downhole, non-drilling operations, including, fishing and retrieval operations as well as underreaming or casing cutting operations and the like. A condition sensing device is used to measure downhole operating parameters, including, for example, torque, tension, compression, direction of rotation and rate of rotation. The operating parameter information is then used to perform the downhole operation more effectively.Type: GrantFiled: February 11, 2004Date of Patent: September 22, 2009Assignee: Baker Hughes IncorporatedInventors: James A.
