  • Patent number: 9708879
    Abstract: An apparatus (10) and method, particularly useful for isolating zones in a hydrocarbon open hole well bore (80). The apparatus includes a tubular body (12), arranged to be run into and secured within the well bore. A sleeve member (14) is positioned on the exterior of the body and is sealed thereto creating a chamber (16) therebetween. Pressure is applied through a port (18) in the body to cause the sleeve member to move outwardly and morph to an inner wall of the well bore. Pressure is trapped in the chamber and maintained at a morphed pressure value by pressure balancing means in the form of a biased piston (64).

  • Patent number: 9695667
    Abstract: An electrical submersible pump system includes an electric motor operably coupled to a fluid pump which includes first and second fluid ports. The first and second ports are selectively operable as a fluid intake and a fluid discharge of the fluid pump with reversal of a direction of rotation of the fluid pump. Valves in the system are controllable to selectively direct fluid discharge of the fluid pump to an inflation volume of the inflatable packer and toward the surface in a wellbore tubing. The valves are further controllable to vent pressure in the inflation volume to deflate the packer.

  • Patent number: 9683425
    Abstract: A downhole injection tool has an injection unit with a first expandable cup adapted to provide a first seal against the inside wall, and a second expandable cup adapted to provide a second seal against the inside wall. The two cups, in an expanded state, together define an isolated zone of the annular space. At least one pipe element extends in a longitudinal direction between the two cups, the pipe element providing a fluid passage between an inlet arranged in one end of the pipe element and an outlet arranged in the pipe element in between the cups, the second expandable cup being slidably connected with the pipe element and displaced in the longitudinal direction away from the first expandable cup under the influence of the injection fluid injected into the isolated zone, whereby a distance d between the two cups is increased.

  • Patent number: 9637985
    Abstract: Certain aspects are directed to a device designed to relieve compression in a length of pipe. The device provides a load ring that can absorb and isolate load until a shear sleeve is shifted and shear pins are sheared. A specific aspect provides a packer release compaction joint that has a shifting sleeve having a first internal shoulder configured to engage a shifting tool; a shear sleeve having a raised abutment; a load ring mounted on the shear sleeve, the load ring having an outer diameter and positioned forward of the first side of the raised abutment; a snap ring mounted around the outer diameter of the load ring. Action of a shifting tool against the first internal shoulder of the shifting sleeve causes the snap ring to move away from the load ring and move to the second side of the raised abutment.

  • Patent number: 9574432
    Abstract: The invention provides a method of optimizing the rate of penetration of a hydraulically or pneumatically powered rotor and stator driven drill as it drills a wellbore into the earth, the method comprising: (a) measuring a first set of rotor and stator operating parameters including the weight applied to the drill bit, the speed of rotation of the rotor and rotor torque for a first period of time, (b) generating a first set of relationships from the first set of operating parameters to enable the rotor speed and rotor torque to be predicted over a range of operating parameter values, (c) determining the rate of penetration for the first period of time from measurements of weight applied to the bit and rotation speed of the bit, (d) determining whether any other combination of weight applied to bit and rotation speed of bit, provided by the relationships determined in step (b) are capable of providing a greater rate of penetration, and (e) adjusting at least one operating parameter to move the weight applied t

  • Patent number: RE46746
    Abstract: In a mud-lubricated bearing assembly for a downhole motor, a mechanical seal is provided between the mandrel and the lower end of the bearing housing to prevent discharge of drilling fluid (mud) from the bearing assembly into the wellbore annulus. The mechanical seal is effected by mating wear-resistant annular contact surfaces provided on the mandrel and the bearing housing, with biasing means preferably being provided to keep the contact surfaces in sealing engagement during both on-bottom and off-bottom operational modes. The diverted drilling fluid passing through the bearings is redirected into the bore of the mandrel via ports through the mandrel wall to rejoin the main flow to the drill bit, such that substantially all of the drilling fluid flows through the bit.
