    Abstract: A pivot drive, a pivot, a cutter drive, a cutting head, and a camera are mounted to a base, and a remote control system operates the pivot drive to pivot the cutter drive from a stored to a use position, operates the cutter drive to rotationally drive the cutting head, and operates the camera to provide images of the cutting head used to cut out blockages at lateral connections of relined pipes. The camera and the cutting head are positioned in a spaced apart relationship facing each other, with the base extending beyond the cutting head sufficiently to provide this spacing. Optionally, the camera is mounted to a trailing portion of the base and the cutter drive is mounted to a leading portion, with control lines for the pivot and cutter drives routed back past but retained separated from the cutting head to avoid damage.

After a lateral is drilled the BHA is retracted and the support string is manipulated to advance the whipstock to a new location for proper orientation with a gyroscopic tool. The BHA is then advanced through the support string for drilling of another lateral in the same trip in the hole. The process can be repeated as many times as needed. Peripheral pads on the lower end of the whipstock push the lower end of the whipstock ramp to the borehole wall for proper tracking of the lateral.

  • Patent number: 8776900
    Abstract: A process for recovering hydrocarbons from an in situ formation. The process includes the steps of injecting solvent though an injection well into an underground extraction chamber having a hydrocarbon extraction interface, warming the hydrocarbons at the extraction interface to cause the hydrocarbons to flow downwardly by gravity drainage. Barrier gases naturally emerge in the chamber as a result of the extraction process and are removed from the extraction interface to improve heat transfer from said solvent to said interface. The last step is to recover liquids such as hydrocarbons and water through a production well. The invention provides a separate flow path to remove hydrocarbon gases from the chamber at a preferred location. The preferred location is near the top of the chamber where the accumulated barrier gases help to limit the heat loss and can also provide a barrier to help maintain chamber integrity and confinement.

    Abstract: A wellbore system to produce natural gas and/or oil from high pressure shale or tight rock formations using a profusion of open hole sinusoidal laterals to achieve comparable contact surface areas with multi-stage hydraulically fractured wellbores. The laterals are drilled in an orientation designed to intersect the dominant natural fracture system and are also drilled in a sinusoidal pattern to interconnect the individual rock facies within the targeted subterranean zone. The sequence of lateral drilling is toe to heel, with the open hole kickoff in the downward direction to facilitate easy re-entry upon drill string tripping. By drilling enough laterals to achieve comparable contact surface area with hydraulically fractured wells, the subject invention allows for comparable quantities of natural gas and/or oil to be produced from high pressure shale or tight rock formations at significantly lower capital cost.

    Abstract: A downhole tool for use in a multilateral wellbore includes a guide member on one end that selectively projects into a designated wellbore, where the designated wellbore can be a motherbore or a lateral wellbore. Pistons are set radially in a body of the tool that selectively push against an end of the guide member to pivot it into a designated orientation to guide the tool into the designated wellbore. The pistons are hydraulically actuated when probes that are on sides of the tool body extend outward into contact with a lateral wellbore. The probes block hydraulic flow when retracted, but when deployed outward they allow fluid communication to push the pistons against the guide member.

  • Patent number: 8701770
    Abstract: A well system includes a main wellbore extending from a terranean surface toward a subterranean zone. A first lateral wellbore extends from the main wellbore into the subterranean zone. A second lateral wellbore extends from the main wellbore into the subterranean zone. A liner junction device resides in the main wellbore and has a first leg extending into the first lateral wellbore and a second leg extending downhole in the main wellbore. A treatment fluid injection string extends from in the main wellbore through the liner junction and into the first lateral wellbore and terminates in the first lateral wellbore. A seal in the first lateral wellbore seals against flow toward the main wellbore in an annulus adjacent an outer surface of the treatment fluid injection string.

  • Patent number: 8701775
    Abstract: A method for completion of a lateral wellbore using a high pressure multibore junction assembly, which comprises a tubular main leg and a tubular lateral leg. The tubular main leg is secured within a main wellbore and the tubular lateral leg is positioned through a lateral wellbore. The tubular main leg and the tubular lateral leg may be stabilized relative to each other as the multibore junction assembly is lowered into the main wellbore.

  • Publication number: 20140102710
    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: 8695695
    Abstract: A downhole tool for use in a well. The tool has a packer assembly and a pumpable plug associated with the packer assembly. The pumpable plug has a diameter greater than the maximum outer diameter of the packer assembly. The pumpable plug may be pumped through a casing having a diameter larger than that for which the packer assembly is designed and will urge the packer assembly through the large diameter casing into a smaller diameter casing for which the packer assembly is designed.

  • Patent number: 8695730
    Abstract: Systems and methods for drilling a multilateral well using magnetic ranging while drilling are provided. In accordance with one embodiment, a method of drilling a multilateral well includes drilling and casing a mother wellbore, installing a multilateral junction, drilling and casing a first lateral well from the multilateral junction, and drilling a second lateral well from the multilateral junction using magnetic ranging while drilling such that the second lateral well has a controlled relationship relative to the first lateral well. The first and second lateral wells may form a SAGD well pair, in which case the first lateral well may be a producer well and the second lateral well may be an injector well.

  • 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.
