  • Patent number: 9133684
    Abstract: A downhole tool comprising an inner sleeve with a plurality of sleeve ports and a housing positioned radially outwardly of the inner sleeve and having a plurality of housing ports, with the housing and inner sleeve partially defining a space radially therebetween. The space is occupied by a shifting sleeve. A fluid path extends between the interior flowpath of the tool and the space. A fluid control device, occupies at least portion of the fluid path, and may selectively permit fluid flow, and thus pressure communication, into the space to cause a differential pressure across the shifting sleeve. When a sufficient differential pressure is reached, the shifting sleeve is moved from a first position to a second position, which opens the communication paths through the housing and sleeve ports between the interior flowpath and exterior of the tool.

  • Publication number: 20140076535
    Abstract: A hydraulically actuated setting tool has a plurality of pistons that move in tandem when unlocked. The pistons are initially in pressure balance to take a load off a single locking mechanism that retains all the pistons. The pistons move due to admission of hydrostatic and/or applied pressure from the annulus on one side of each piston with an opposite side exposed to atmospheric pressure. The locking member is exposed to the annulus and is located away from any atmospheric chambers associated with the pistons. In this manner the components can be made thicker to resist burst and collapse pressure and the loads on the locking member reduced due to initial piston pressure balance configuration. Depths of greater than 8,000 meters can be used due to one or more of the described design features.

  • Publication number: 20090242190
    Abstract: A downhole shock absorber preferably is filled with well fluid in a chamber that is reduced in volume due to impact. A rupture disc can hold the initial non-compressible liquid charge until impact. Upon impact, the rupture disc breaks to allow the fluid to be forced through an orifice to absorb some of the shock that occurs when a string hits a fixed object after dropping in the wellbore. The nose of the shock absorber is a soft material that has voids so that the combination of the softness of the material and the voids allow the nose to reshape until it encounters a surrounding tubular wall and then to collapse inwardly into the voids, making it simple to remove. The nose is releasably mounted to the shock absorber so the two can separate if the nose gets stuck after impact.

  • Patent number: 6920933
    Abstract: A platform is used to deliver a tool down a hole by controlling the flow of fluid through and around the platform. The platform has a top surface for receiving the tool. The platform also has a bottom surface to provide guidance through and resistance to the flow of fluid. The lower surface of the platform can be engineered to steer the platform against an inner wall of the casing. This slows the descent by adding mechanical friction to its descent. The lower surface can also be engineered to add a predetermined amount of resistance to the flow of the well fluid across it. A stop on the casing already in place in the well stops the descent of the tool at a desired depth. Once the tool is no longer needed, a fishing tool can be lowered from the same crane to retrieve the tool and platform. Use of a crane substantially decreases the cost of the operation compared to the need for a rig.

  • Patent number: 6527057
    Abstract: An apparatus and method for delivering a liner wiper plug into a well bore on a workstring with a liner pipe, releasing the wiper plug from the workstring, and giving a positive indication of release of the wiper plug. A sleeve captures a collet to a latch ring until a plug is pumped down the workstring to cause a pressure buildup, which shears a shear screw, allowing the sleeve to shift, releasing the latch ring and the wiper plug from the workstring. A rupture disk is provided in the event of jamming of the apparatus, to allow pressurization above the wiper plug, shearing a weak link in the latch ring to release the wiper plug.

  • Patent number: 6457517
    Abstract: A composite landing collar is disclosed which is preferably adhesive bonded to the liner string using a high temperature epoxy. The spacing during bonding is maintained within dimensional limits using spacers. The body features a bi-directional material, with an appropriate ratio in the warp and fills directions, for about a quarter of the wall thickness. A unidirectional material with the fibers axially aligned aids in reduction of thermal stresses in the thick wall during curing, as well as reducing shear stress concentration along the adhesive bonding interface.
