Abstract: A lateral exit in a casing is formed by starting with a shaped charge to produce a semi-circular cut of about 180 degrees in the casing. A spreader tool pushes in opposed directions at opposed ends of the cut making some of the casing wall at the cut curl inwardly. A wedge shaped tool is advanced behind the curled metal to force it to collapse on itself to create a long tapered ramp that act as would a whipstock. A one trip operation is contemplated. The drill is then guided by the doubled and tapered casing wall right into the formation without having to mill a window in the casing wall.

Abstract: A casing cutting and recovery tool having a cutting assembly, an expansion assembly having one or more deforming members, and a recovery assembly is used to cut a window in wellbore casing, secure a removable segment of wellbore casing that was previously disposed within the window, and recover the removable segment of wellbore casing with the tool. One or more cutting assemblies provides one or more cuts in the wellbore casing. The deforming members of the expansion assembly then expand outwardly at least two portions of the wellbore casing shaped by the cut or cuts. The recovery assembly secures the removable segment of the wellbore casing to the tool so that the tool and the removable segment of wellbore casing can be recovered together from the wellbore.

Abstract: A through tubing centralizer is delivered below the tubing and expanded against a surrounding tubular for fixation. In a window milling through tubing application, a whipstock is delivered through tubing and anchored. One or more centralizers are then delivered through tubing and expanded so that their inside diameter when set exceeds their outside diameter during run in. They are placed below the tubing and above the whipstock to help a through tubing mill stay on the whipstock ramp while milling the window. After the window is started, the centralizer can be expanded fully against the surrounding tubular to allow subsequent removal of the whipstock. Optionally, the centralizer can be collapsed for removal through tubing.

Abstract: A flow sensor is incorporated into a junk basket to sense a flow stoppage due to a plugged screen or plugged cuttings ports in a mill. The sensor triggers a signal to the surface to warn personnel that a problem exists before the equipment is damaged. The sensor signal to the surface can take a variety of forms including mud pulses, a detectable pressure buildup at the surface, electromagnetic energy, electrical signal on hard wire or radio signals in a wifi system to name a few options. Surface personnel can interrupt the milling to take corrective action that generally involves pulling out of the hole or reverse circulating to try to clear the screen or mill cuttings inlets. Other variables can be measured such as the volume or weight or rate of change of either and a signal can be sent to the surface corresponding to one of those variables to allow them to be detected at the surface in real time.

Abstract: A method and apparatus for milling a section of casing in an upward direction, utilizing a downhole hydraulic thrusting mechanism for pulling a section mill upwardly. A downhole motor and torque anchor can be used to rotate the section mill, or the mill can be rotated by a work string. A stabilizer above the section mill can be used to stabilize the mill relative to the casing being milled. A spiral auger below the section mill can be used to move the cuttings downwardly.

Abstract: The present invention provides a system for performing a suitable operation in a wellbore utilizing a resonator. The system includes a resonator for generating pulses of mechanical energy, an engaging device for securely engaging an object in the wellbore and a sensor for detecting the response of the object to pulses generated by the resonator. The resonator is placed at a suitable location in the wellbore and the engaging device is attached to the object. The resonator is operated at an effective frequency to induce pulses into the object. The sensor detects the response of the object to the induced pulses, which information is utilized to adjust the operating frequency. The system in different configurations can be used to fish, free a stuck drill string, aid drilling of wellbores and to perform a cementing operation. A control circuit controls the operation of the system according to programmed instructions.

Abstract: A combination metal milling and earth drilling tool, for use in performing a single trip kickoff from a casing in a well bore. The combination milling and drilling tool has a first, relatively more durable cutting structure, such as tungsten carbide, and a second, relatively harder cutting structure, such as polycrystalline diamond. The more durable first cutting structure is better suited for milling metal casing, while the harder second cutting structure is better suited for drilling through a subterranean formation, especially a rock formation. The first cutting structure is positioned outwardly relative to the second cutting structure, so that the first cutting structure will mill through the metal casing while shielding the second cutting structure from contact with the casing. The first cutting structure can wear away while milling through the casing and upon initial contact with the rock formation, thereby exposing the second cutting structure to contact with the rock formation. The second cutting structure can then be used to drill through the rock formation.

Abstract: A casing patch is disclosed which uses one or more fins which elastically flex to accept a casing stub. The casing stub is prepared with a dressing tool containing a special mill to obtain the requisite finish on its outer surface prior to insertion of the casing patch. The flexible fin or fins provide a metal-to-metal seal to the outer surface of the casing patch and a grip assembly holds the joint together. In certain applications, the fins can be combined with a resilient seal where the fins preferably provide a complete extrusion barrier to the resilient seals. Using the fins which preferably are integral to the body, alone or in combination with a resilient seal or seals, the wall thickness of the joint can be maintained at thicker values for a given size as compared to prior designs, thus, ensuring a sufficient pressure rating for the joint which is at least equal to the rating of the casing stub.
