  • Patent number: 9617825
    Abstract: A tool equalizes a packer or bridge plug before it can release the slips and sealing element of the packer or bridge plug with a reconfigurable grip tool. In one configuration the grip tool is latched only into the equalizing mechanism for the packer or bridge plug. Having equalized the pressure and while still latched to the equalization mechanism the tool is reconfigured with a force and locked into a second configuration. From that position the grip tool can latch and move the release mechanism for total release and retrieval to the surface. Release force undermines a ratchet lock for the slips to allow extension as the sealing element extends axially and radially retracts. If the slips fail to release with undermining of the ratchet lock then a set down force can be applied to re-engage the lower slip cone to push it from the lower slips for a release.

  • Patent number: 9540913
    Abstract: A method and apparatus are presented for actuating a differential pressure firing head to actuate a perforating gun at a downhole location in a subterranean wellbore adjacent a formation. An exemplary method includes positioning the perforating gun and the differential pressure firing head at a downhole location on a tubing string and then communicating an applied fluid pressure to a wellbore annulus, a first chamber which communicates the applied fluid pressure to a low-pressure side of the firing head assembly, and a second fluid chamber which communicates the applied fluid pressure to a high-pressure side of the firing head assembly. The applied fluid pressure is then trapped within the second fluid chamber. When the applied pressure in the annulus is subsequently removed, a pressure differential is created across the firing head by the low pressure in the first chamber and the trapped applied pressure in the second chamber.

  • Patent number: 9528323
    Abstract: A fluid drilling head for drilling a bore hole through rock. The fluid drilling head has a rotatable nozzle assembly incorporating a plurality of nozzles arranged to form fluid jets when provided with a supply of drilling fluid under pressure. The fluid jets include pilot jets directed in the general direction of movement of the drilling head and reaming jets directed generally radially and arranged to enlarge the initial hole formed by the pilot jets. A gauging ring is located behind the cutting head and sized to the intended diameter of the bore hole. The gauging ring is arranged to slide axially relative to the rotating cutting head between a rearward position where the reaming jets are exposed, and a forward position where some or all of the reaming jets are shrouded by the gauging ring and inhibited from enlarging the diameter of the bore hole.

  • Patent number: 9500031
    Abstract: A rotary steering apparatus for a drill string in which a bending section induces a bend in a portion of the bottom hole assembly of the drill string by using the rotation of the drive shaft that drives the drill bit during normal drilling, while operating at a reduced or zero drilling mud flow rate, to drive a reduction gear that rotates a nut or cam so as to place a tension tube into tension. The tension tube abuts a flexible housing and places the flexible housing in compression. The flexible housing has a local weakening formed in it that causes it to preferentially bend in a predetermined direction. Compression in the flexible housing causes the housing to bend, which bends a portion of the bottom hole assembly so as to alter the direction of drilling. Rotation of the drive shaft at reduced or zero mud flow rate also causes the drive shaft to drive rotation of a second reduction gear the output of which rotates the bent portion of the bottom hole assembly thereby altering its tool face angle.

  • Patent number: 9494014
    Abstract: A circulating valve assembly can include a valve controlling flow between an interior and an exterior of the assembly, another valve controlling flow between sections of a flow passage extending through the assembly, and an actuator that both opens one valve and closes the other valve in response to each of multiple positive pressure differentials from the interior to the exterior. A system for use with a well can include a circulating valve assembly controlling flow through a tubular string and a well tool connected in the tubular string downstream of the assembly. In one configuration of the assembly, the flow passes through the well tool. In another configuration, the flow passes from the tubular string to an annulus external to the tubular string, with the flow substantially bypassing the well tool. The assembly cycles between the configurations in response to alternating increases and decreases in the flow.
