  • Patent number: 9719334
    Abstract: A tool and method employing sand jetting to perforate a wellbore casing at various locations using sandjetting, and to further flush the wellbore in the region of the tool, and to further frac the formation, all without having to remove the tool from the wellbore. An uphole and downhole packer is provided, uphole of which a sand jet port is provided for jetting a fluid stream containing sand. Locking jaw members and a ‘j’ slot subassembly, downhole of both the jet port and frac port, are together used to set and unset the tool in the wellbore for the fracking operation. A slidable sleeve is utilized to open and close the jet port, and a piston member is further provided to set the upper packer member. A bypass port, selectively openable and closeable, is provided to assist in moving the tool uphole during the perforating and fracking process.

  • Patent number: 9605510
    Abstract: A wellbore cementing tool configured for placement in a wellbore or in a drill string, and method of using same. The tool comprises a body having upper and lower members connected by a shear component. A rod is connected to the upper member, and the tool can be lowered with the rod into the wellbore or drill string to a desired depth. At the desired depth, locking means are deployed to lock the tool in position, the tool is sealed, and cement can be injected through the tool to the annulus of the outer casing. In some embodiments the tool is locked using a pushing motion that extends locking members outwardly from the tool to engage the wellbore walls or the inner surfaces of the drill string. Once cementing is completed, the rod is pulled from surface thereby causing the shear component to rupture and the upper and lower members to disconnect, and the upper member can be drawn to surface leaving the rest of the tool downhole.

  • Patent number: 8915305
    Abstract: A packer tool has safety devices to prevent premature and reverse setting and release operations. The safety devices are independent of shear-pin safety systems. Confined annular segments prevent a setting actuator piston from moving absent tool-setting hydraulic pressure. The setting pressure first moves a cylinder in an opposite direction to unroof the segments allowing them to exit confinement and free the piston to set the packing and the anchor slips. Release safety pins extend radially inward from a packing-holder collar into short slots formed on a mandrel surface, preventing the mandrel from being turned. Previous set motion causes the pins to leave the slots thereby freeing the mandrel to turn only after the tool has been set. A third safety device comprises an expanded ring which is dragged by the release cone during release motion until it lodges in a circumferential groove in the mandrel, locking against reverse movement.

    Abstract: Shear member designs in various formats are presented with additional features for segment retention and subsequent removal after a shearing event and removal of the tool from a subterranean location. In some embodiments a portion of the shear member is retained by threads so that the segment stays in the part and then can be removed at the surface with putting a notch in the segment and removing it with a screwdriver. In another embodiment a retaining pin in an intersecting bore can hold onto a sheared remnant of the shear pin by pushing the remnant laterally in the bore that it is mounted. Another design for a shear ring uses a split design with the right angle portion of the ring that gets sheared appearing in segments so that the ring can be rapidly snapped into a groove at its outer periphery followed by a retaining cap facilitating removal.

  • Patent number: 8794309
    Abstract: Slip members for use with downhole tools comprise a body formed of a first or body material and one or more hard material elements formed of a second or element material. The element material is harder than the body material. The hard material element is disposed through the body and in communication with a first surface and a second surface of the body, the second surface being disposed opposing the first surface. During manufacturing of the slip members, the hard material element may extend outwardly from one or both of the first and second surfaces. After manufacturing, the hard material element can be shaped to provide a gripping member.

  • Patent number: 8763686
    Abstract: A linkage device separate from the integrated slips bridge links the pair of spaced-apart members of each slip to prevent sizeable fractured bits from moving away in the event of a fracture in the slip. The linkage device comprises a pair of ductile steel bars the ends of which loosely anchor in holes in each slip member, the holes being located at both sides of the slips at opposite ends of a groove that houses the linkage bar preventing it from falling out of the holes. In this way, a fractured slip may continue to assist in setting the tool and, moreover, potential hazardous interference in further tool operations are avoided. Furthermore, tool damage including slips fracture is reduced by a resilient damper material which buffers the lower cone as it slides down on the slip-holder cage during a tool release operation.
