  • Patent number: 10267131
    Abstract: An apparatus and methods for forming a transverse fracture in a subterranean formation surrounding a wellbore including measuring a property along the length of the formation surrounding the wellbore, forming a stress profile of the formation, identifying a region of the formation to remove using the stress profile, removing the region with a device in the wellbore, and introducing a fluid into the wellbore, wherein a transverse fracture is more likely to form than if the region was not removed. Some embodiments benefit from computing the energy required to initiate and propagate a fracture from the region, optimizing the fluid introduction to minimize the energy required, and optimizing the geometry of the region.

  • Patent number: 10260301
    Abstract: A string from the surface is connected to a packer extension with a thread to provide a metal to metal seal for production or injection through the packer. The thread provides a metal to metal seal. The initial string is released from the packer extension by a tubular cut made with a cutting tool above the thread that provides the metal to metal seal to the packer extension. An outer sleeve surrounds an expanded length of wall which is the target cut zone above the threaded connection. A cut through the tubular does not cut the outer sleeve. The outer sleeve features a left handed square thread to engage a known released tool run in on a string to connect to the packer release mechanism and release the packer for removal with the release tool suspended from a string.

  • Patent number: 10233724
    Abstract: An element is deployed within tubing extending to a downhole tool. The downhole tool includes a hydraulic tool and a valve coupled between the conveyance string and the hydraulic tool. The valve includes a valve seat having a passage directing the fluid from the conveyance string to the hydraulic tool. Deploying the element includes landing the element on the valve seat such that the element substantially obstructs flow of the fluid through the valve seat passage. The valve is opened to direct the flow of the fluid around the hydraulic tool, wherein opening the valve utilizes pressure generated in response to the element obstructing the flow of the fluid through the valve seat passage. At least a portion of at least one of the element and the valve seat is then degraded by an amount sufficient to permit the element to pass through the valve seat passage.

  • Patent number: 10221670
    Abstract: Produced water, for example from a steam assisted gravity drainage (SAGD) or cyclic steam stimulation (CSS) heavy oil recovery operation, is treated to recover water that is re-used to create steam. The produced water is treated in one or more thermal treatment devices such as an evaporator and a crystallizer. The thermal treatment device is seeded, for example with a calcium or magnesium salt. The thermal treatment device produces a blowdown or slurry comprising super-saturated solids and organic compounds. A solvent is added to the blowdown or slurry. The solids precipitate and are separated from the blowdown or slurry. The solvent may be recovered for re-use in treating more blowdown or slurry.

  • Patent number: 10214980
    Abstract: A sensor assembly may include a housing made of a non-magnetic material. The housing may define an interior chamber. A shaft may extend from the housing. A bearing may be positioned around the shaft. An impeller may be positioned around the shaft and the bearing, and the impeller may include a magnetized portion. A sensor may be positioned within the interior chamber and/or proximate the magnetized portion. The sensor may detect the magnetized portion of the impeller to sense a rate of rotation of the impeller. The rate of rotation of the impeller may correspond to changes in flow rate of the fluid. As the flow rate of the fluid, and the rate of rotation of the impeller change in predetermined manners, control signals may be conveyed to activate a tool.
