    Abstract: A wellbore assembly comprises a tubular member adapted to be connected to other tubular members, the tubular member having a side wall defining a hollow interior and an array of openings therethrough to permit material into the interior. A screening element extends about the tubular member over the array of openings to control the material that reaches the array of openings. A stress relieving arrangement associated with the screening element permits relative movement between the screening element and the tubular member to absorb stress build-up within the screening element whether due to mechanical or temperature induced forces that would tend to distortion the screening elements. In a preferred arrangement, the wellbore assembly serves to maintain solids control in production wells while accommodating stresses and strains that occur within the tubular members in those wells.

  • Perforating Gun Spacer
    Publication number: 20130105146
    Abstract: Perforating gun connectors are provided with a small diameter inner tube to house the detonating cord and an outer load-bearing tube that is ported to be in pressure balance. The inner tube controls the volume in the gun for the well fluids to enter after the guns are fired and the initial pressure surge dissipates. The smaller diameter also increases pressure rating and diminishes the chance of plastic deformation. Since the inner tube is inset even some deformation is tolerated without distorting the outer tube due to the space between the tubes. Alternative embodiments with a bored rod as a housing member or with a layered single outer wall effect are also contemplated.

The casing string is perforated to allow fluid from the upper reservoir to flow through the cement free zone. A tubing string is landed and set within the casing string. The tubing string is sealed above and below the perforation at the cement free zone to prevent communication between fluid from the upper reservoir and the lower reservoir. The upper reservoir is monitored at the cement free zone, and the lower reservoir is monitored below an end of the tubing string.

    Abstract: A method is given for diverting injected slickwater in a hydraulic fracturing treatment. The diversion fluid is preferably a substantially proppant free viscous fluid that causes a net pressure increase and plugging of some of the microfractures in the initial fracture system created, which induces formation of supplementary microfractures connected to the initial fracture network and in-creases the contact area with the formation rock. The method generates a greater fracture network complexity and thus a higher contact area with the reservoir during a single treatment cycle.

    Abstract: A method of sealing a well comprising introducing a plug axially into the well, with a mouth of the plug turned up and a bottom wall part turned down, the plug being positioned in the well at a desired depth, after which the plug is inflated by injecting a high-pressure liquid into it via its mouth so that a tubular wall part of the plug expands radially beyond its elastic limit and presses firmly and tightly against the wall of the well by a crimping effect, while its bottom wall part serves as a sealing partition, forming a tight barrier between lower and upper parts of the well that it separates, the plug having an internal axial mandrel that connects its mouth to its bottom wall, the mandrel being pierced with channels that allow injection of high-pressure liquid inside the plug via the mouth and channels.

  • Compositions and Methods for Well Treatment
    Publication number: 20130105160
    Abstract: A self-healing cement for use in wells in which carbon dioxide is injected, stored or extracted, comprises a carbonaceous material. In the event of cement-matrix failure, or bonding failure between the cement/casing interface or the cement/borehole-wall interface, the material swells when contacted by carbon dioxide. The swelling seals voids in the cement matrix, or along the bonding interfaces, thereby restoring zonal isolation.

  • Delayed, Swellable Particles for Prevention of Fluid Migration Through Damaged Cement Sheaths
    Publication number: 20130105161
    Abstract: A method includes providing a cementing composition that includes an aqueous fluid, a cementitious particulate, and a copolymer particulate which includes a monofunctional monomer, a water degradable first crosslinker, and a second crosslinker. The method further includes placing the cementing composition in a subterranean formation so as to form a set cement sheath and swelling the copolymer particulate in response to a void created in the set cement sheath. The copolymer particulate allows the cementing composition to set to form the cement sheath before substantial swelling of the copolymer particulate occurs.

  • COMPOSITIONS AND METHODS FOR IMPROVING THE TOUGHNESS OF SET CEMENTS
    Publication number: 20130105162
    Abstract: The toughness of set cement may be enhanced by incorporating partially cured waterborne resins in the cement matrix. A hardening agent is added to the waterborne resin, and the mixture is allowed to react for periods between about 1 min and 15 min. The waterborne resin with hardening agent is then combined with an inorganic cement to form a pumpable slurry. After curing, the set cement may withstand at least 1.5% strain before failure.

  • MEASUREMENT OF RELATIVE TURNS AND DISPLACEMENT IN SUBSEA RUNNING TOOLS
    Publication number: 20130105170
    Abstract: A running tool generates signals in response to setting of a subsea wellhead device that correspond to actual rotation and displacement of the running tool in the subsea wellhead. The running tool includes an encoder that generates a signal corresponding to the number of rotations of a stem of the running tool relative to a body of the running tool. The running tool also includes an axial displacement sensor that generates a signal corresponding to the axial displacement of a piston of the running tool relative to the body. The signals are communicated to the surface using an acoustic transmitter located on the running tool and an acoustic receptor located proximate to a drilling platform at the surface. The signals are communicated to an operator interface device from the receptor for further communication in a manner understood by an operator.

  • DISCHARGE PRESSURE ACTUATED PUMP
    Publication number: 20130105173
    Abstract: A pump has a pump barrel formed from a larger diameter section and a smaller diameter section. Each section has a biased piston moveable within the section and the pistons are connected together to form a variable volume chamber between the pistons. As the connected pistons move toward the larger diameter section, a volume of fluid is moved through an inlet valve into the variable volume chamber of increasing volume. When the pistons are moved toward the smaller diameter section, a differential volume of fluid is discharged from the variable volume chamber of decreasing volume through a discharge valve into a discharge conduit. The pistons are actuated to move within the pump barrel by application and release of pressure at a remote end of the discharge conduit.
