    Abstract: A junction can be isolated from fracturing pressure using a liner extending from a one bore through a junction into a lateral bore, where at least a portion of the liner is retrievable from the lateral bore prior to completion of wellbore construction. The junction may be temporarily isolated from high pressure, such as high pressure from a fracturing stimulation process. Part of the liner can be retrieved using a disconnect mechanism or technique.

  • Patent number: 8695694
    Abstract: A deflector assembly includes two deflectors that can cooperate for directing a bullnose assembly toward an intended bore in a multi-bore well based on a configuration of the bullnose assembly without requiring use of gravitational forces or requiring the assembly to be oriented in a certain manner. The deflectors can cooperate by being spaced by a certain amount that, depending on if the amount is less than or greater than a longitudinal length and diameter of a bullnose of the bullnose assembly, can allow the bullnose assembly to be diverted toward the intended bore.

  • Patent number: 8678092
    Abstract: A multilateral completions assembly having selectively isolated lateral legs during hardware installation. The assembly includes a variety of isolation sleeves disposed interior of the main bore casing and adjacent corresponding pre-located windows through the casing. Thus, lateral legs may be sequentially created through the formation at each window in a manner that allows for follow-on isolation. As a result, fluid losses from newly formed legs may be avoided during completions operations. That is, as each leg is formed it may also be isolated in advance of forming of the next leg thereby enhancing the efficiency of completions operations as well as follow-on production.

  • Patent number: 8607858
    Abstract: A whipstock features a spiral ramp so that, in a horizontal run, access to a milled window with other tools is not impeded because such tools can traverse onto the ramp and still be directed to the window. Angular rotation of the ramp can be at 180° or more and the pitch is selected to avoid getting the equipment being advanced into a bind. Optionally, a guide track can be configured into the whipstock ramp to help the mill follow the spiral path until the proper orientation is obtained and the track ends to allow separation of the mill from the track. A slot can be provided near the ramp upper end to aid in retrieval operations.

  • Patent number: 8602097
    Abstract: Assemblies that can be disposed in a subterranean bore. An assembly can include a body with an opening in a wall of the body. A sleeve can be disposed exterior to the body at the opening. The sleeve can be made from material such as carbon fiber that can withstand at least some pressures and forces present in the subterranean environment and reduce a diameter of the body and sleeve. The assembly may also include an inner sleeve and/or an inner string that can isolate the sleeve from certain pressures and forces.

  • Patent number: 8590608
    Abstract: A multilateral access system for a multilateral well including a main well bore and at least one lateral well bore includes a tubular workstring having an inner string and an outer string. The outer string includes a diverter body having a cylindrical housing with a lateral window, the diverter body being shaped and dimensioned to direct the inner string the lateral window and into the at least one lateral well bore. The system is used by positioning the tubular workstring within a multilateral bore. The method further includes positioning the diverter body such that the window of the diverter body faces a milled casing window of the lateral well bore and moving the inner string upwardly above the diverter body. Subsequently, the inner string is lowered back though the diverter body, wherein the diverter body exerts a lateral force on a lower end of the inner string urging the lower end of the inner string toward the milled casing window.

  • Patent number: 8567527
    Abstract: A system and method is provided for drilling a wellbore using a rotary drill bit with a bit body having a plurality of mechanical cutters to cut away formation material as the wellbore is formed; and a directed energy mechanism to direct energy into the formation. The energy from the directed energy mechanism is used to enhance the cutting of the mechanical cutters by fracturing surrounding material to facilitate drilling in the direction of the directed energy.

    Abstract: An apparatus and method for penetrating earth strata surrounding a wellbore including a nozzle assembly, a flexible tubing connected to the nozzle assembly, and a means to position the nozzle assembly downhole in a substantially horizontal direction into earthen strata, such that the nozzle assembly is connected to one end of the flexible tubing. Embodiments can provide horizontal jetting into the earth's strata from both cased and uncased wells utilizing a rotating, swirling, pulsing or cavitating nozzles which can keep a relatively cuttings free downhole environment.

    Abstract: A downhole apparatus for depositing a tool in a side pocket mandrel is described. The apparatus comprises an apparatus body, a tool holder and a displacement mechanism for connecting the tool holder to the apparatus body. The tool holder is movable between a run-in position, in which the tool holder is adjacent the body, to a displaced position, in which the tool holder is spaced away from the body As a tool is moved between the run-in position and the displaced position, a tool longitudinal axis remains substantially parallel to an apparatus body longitudinal axis.

  • Patent number: 8505621
    Abstract: Assemblies can be disposed in a subterranean bore. An assembly can include a recessed portion in an inner wall and another recessed portion in an outer wall. The recessed portions can each be configured to have a cross-sectional thickness that is less than at least another part of the assembly. The assembly can provide a seal between an inner region defined by the assembly and an environment exterior to the assembly prior to a window being created in the recessed portion in the outer wall through which a branch wellbore can be formed. The recessed portion in the inner wall can guide a cutting tool toward the recessed portion in the outer wall.

  • Patent number: 8505622
    Abstract: A tool and method for drilling a secondary hole (window) from a pre-determined position within a well bore into the adjacent rock or formation. The invention includes an internal (relative to the production tubing) primary deflection wedge transitioning into an externally attached (relative to the production tubing) conical device that aids in the exit from the production tubing through the production casing, where a significant standoff exists between the smaller production tubing (completion) and the larger ID production casing. The primary deflection wedge serves as a directional guide to exit the production tubing. The conical device provides a way to transition and support a milling device to exit the adjacent casing at a desired angle without having the milling device move off the preferred course. This two-part assembly is called a tandem wedge kick off assembly.
