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 liner hanger has a housing with a pocket disposed on an inner wall surface and a slip slidingly engaged within the pocket. The liner hanger housing is secured in the string of casing. A setting mechanism connected to the slips is also located in the pocket. An actuator is mounted on the liner. As the liner is moved through the casing coupler, the actuator actuates the setting mechanism, causing the slips to move axially downward. As the setting mechanism moves downward, the slips move radially inward and grip the liner.

Abstract: A liner hanger has a housing with a pocket disposed on an inner wall surface and a slip slidingly engaged within the pocket. The liner hanger housing is secured in the string of casing. Both a setting mechanism and a liner engagement member are connected to the slips and are also located in the pocket. A releasable latching mechanism maintains the slips in the run-in position until the releasable latching mechanism is actuated. As the liner is moved through the casing coupler, the liner engagement member engages the liner through frictional force to cause the setting mechanism to move with the liner so that the latching mechanism can be disengaged and the slips can move axially downward. As the setting mechanism moves downward, the slips move radially inward and grip the liner.

Abstract: Overshot fishing tools for retrieving objects, i.e., “fish” lodged within a wellbore are disclosed. The overshot fishing tool comprises a housing having a housing bore with at least one recess disposed along the inner wall surface of the housing bore. A slip is disposed within each of the recesses. Each slip has a gripping profile for engaging and securing the fish. Each slip also has a length and a width such that the slip, when actuated, provides circumferential loading on the housing. In specific embodiments, each slip includes two or more different gripping profiles to facilitate retrieval of different types and sizes of fish.

Abstract: Milling in casing that is over 4½ inches is done with coiled tubing that is anchored against torque reaction. An improved debris catcher is part of the bottom hole assembly to capture cuttings from the milling. A thruster can be used to maintain weight on the mill during the milling. The coiled tubing supports a mud motor to drive the mill. Return fluid is separated from the cuttings and returned to the surface.

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 signal 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 near real time.

Abstract: Disclosed herein is a method of installing an elastomeric element onto a tubular. The method includes, positioning the elastomeric element onto a radially expandable member, radially expanding the radially expandable member and the elastomeric element installed thereon, positioning a tubular coaxially with the radially expandable member, and axially urging the elastomeric element off the radially expandable member thereby allowing the elastomeric element to be positioned coaxially about an outer perimetrical surface of the tubular.

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: Downhole fluid jet cutting tools having extendible and retractable arms with cutting heads on the ends are disclosed. The jet cutting tools permit casing and other downhole surfaces to be cut utilizing a cutting fluid forced through a jet nozzle assembly. Inflation of an inflatable member within the passageway of the tool moves the jet nozzle assembly when cutting fluid pressure inflates the inflatable member. As a result, a cutting head of the jet nozzle assembly is extended and cutting fluid is forced at high pressure from the passageway to the cutting head where it is expelled through nozzles for cutting casing and the like. The jet cutting tools permit the cutting head to be extended, retracted, and re-extended or redeployed multiple times without the need for being retrieved from the wellbore.

Abstract: Devices and methods for translating tubulars within a wellbore and, as a result, effectively freeing a stuck tubular string within a wellbore. One or more vibrator devices are incorporated into a tubular string, such as a drill string. Each of the vibratory devices may be turned on or off independently, as needed, to help effectively free the tubular string from a stuck condition.

Abstract: Downhole fluid jet cutting tools having extendible and retractable arms with cutting heads on the ends are disclosed. The jet cutting tools permit casing and other downhole surfaces to be cut utilizing a cutting fluid forced through a jet nozzle assembly. Movement of a piston slidingly engaged within the passageway of the tool actuates the arms when cutting fluid pressure acts on the piston. As a result, the arms are extended and cutting fluid is forced at high pressure from the passageway to the cutting head where it is expelled through nozzles for cutting casing and the like. The jet cutting tools permit the arms to be extended, retracted, and re-extended or redeployed multiple times without the need for being retrieved from the wellbore.

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 release mechanism for a downhole tool is actuated by radial movement of a locking member. The locking member provided as much as full circumferential support in the locked position and once released can be prevented from re-gripping the previously connected elements. Illustrative examples of the mechanism for radial movement for release comprise sleeves that expand and radially oriented pistons. Shear pins or collets are not used to hold the components together in the preferred embodiment. Internal pressure fluctuations before initiating the release sequence will not cause unwanted release. The mechanism is applicable to a variety of downhole tools and is illustrated in the context of a hydraulic release.
