摘要： A valve for subterranean whipstock service has a side port and a through passage with a biased movable sleeve to shift between circulation mode into the annulus and flow through mode for setting an anchor and then feeding window mill nozzles. The valve is run in when in circulation mode to allow operation of a measurement while drilling device. When the whipstock is properly oriented the pressure is increased to break a shear pin to allow a spring to bias the sleeve to the flow through position. The shifting of the sleeve opens a bypass passage around the restriction orifice that was first used to build pressure to break the shear pins that let the sleeve move under spring bias. As a result the spring can hold the sleeve in position despite high flow rates needed to remove cuttings from the mill as the window is opened.

摘要： 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.

摘要： A drilling assembly is tripped in a cased hole to make more open hole. The assembly features retracted scrapers and a closed circulation sub so that the drilling can commence with string pressure delivered to bit nozzles due to the circulation sub being in a closed position. When drilling is done and the bit is to be removed, an object lands on a seat on a sleeve that acts as a piston to break scraper retainers for casing scraping deployment and to open the circulation port. A bypass opens around the seated ball when the sleeve shifts to allow flow around the seated ball for circulation while scraping. Drilling and casing scraping are accomplished in a single trip.

摘要： Anchoring systems for disposition in wellbores and tubular devices comprise a tubular member defined by two or more radially expandable slip members. The upper ends of the slip members are shaped such that when the slip members are in their respective run-in positions and in their respective set positions, a portion of an upper end of one slip member overlaps a portion of an upper end of another slip member so that the longitudinal space between each slip member that is created when the slip members are in their set position are blocked by the upper end of at least one of the slip members. Thus, in their set position, the upper end of at least one of the slip members provides a back-up to a sealing element that can be disposed adjacent to and in contact with the upper ends of the slip members when in their set positions.

摘要： A disintegrating plug uses a setting tool to push a swage into the plug body that has external ribs that contact the wall of the surrounding tubular. The ribs retain the body to the surrounding tubular wall with frictional contact. Some leakage may ensue but in fracturing some leakage does not matter if enough volume under the right pressure reaches the formation. The sheared member during the setting comes out with the mandrel that is part of the setting tool. In an alternative embodiment one or more o-rings are used to seal while anchoring is assisted by the hardened insert(s) that can be snap fitted in using rib flexing or that can be a c-ring that is expanded and snapped in. The o-ring(s) are axially spaced from the insert(s).

摘要： A BHA features an MWD tool connected to a running tool supporting a whipstock that is connected to an open hole anchor. The anchor is flow set and after the anchor is set the running tool collets release from the whipstock to allow cement to be pumped through the anchor to hold the set position. The collets are released from the whipstock also with flow and after the anchor has been set. One way is to use nozzles in series. Another is to run in with a ball on the anchor seat, set the anchor and blow out the ball seat so flow can again be used to release the running tool collets. Another is suspending a ball above the anchor seat, releasing the ball with pressure cycle, open another flow passage to allow collet release of the whipstock. Finally, pressure can be used to release the running tool collets.

摘要： A test packer is lowered to a set liner hanger in a locked position that prevents the seal and slips from setting during running in. A first ball is dropped to shift a sleeve to release the grip of dogs to a groove on an outer housing. Setting down weight sets the test packer seal and sets the slips. After the casing integrity pressure test is done the test packer is lifted to again position the groove in the outer housing by the dogs. A second ball lands on the same seat now enlarged due to earlier movement and breaks a retainer on a locking sleeve. A spring return or continued downhole motion of the locking sleeve locks the packer in the run in position. Subsequent rotation and circulation can take place as completion fluid is circulated in. A circulation port above the packer can be opened optionally for circulation or reversing above the test packer.
