Definitions

  • the present invention relates generally to assemblies and methods to be implemented in a wellbore and, more particularly (although not necessarily exclusively), to assemblies and methods for isolating a junction from fracturing pressure and for being retrievable prior to completion of wellbore construction.
  • a junction can be between one bore and another bore.
  • the junction may be one of the weakest points in a casing string of the wellbore system.
  • Forces used to create or complete the well system can affect the casing or the formation exposed at the junction.
  • One example of these forces is from fracture stimulation, such as from fracturing pressure.
  • Some assemblies can help reduce the amount of force experienced by the junction, but these assemblies are relatively large (for example requiring three or more points of isolation) and are implemented after a well system is completed.
  • Assemblies and methods for junction isolation are desirable that can isolate a junction prior to construction of the well system being completed and / or that are smaller. Summary
  • Certain aspects of the present invention are directed to isolating a junction 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.
  • One aspect relates to a liner assembly that includes a liner body and an isolation mechanism exterior to part of the liner body.
  • the liner body is partially positionable at a junction between a bore and a lateral bore of a well system through a subterranean formation.
  • the isolation mechanism can cooperate with the liner body in isolating the junction from fracturing pressure for the lateral bore. At least part of the liner body is retrievable prior to construction of the well system being completed for production.
  • a lateral bore is created in a well system that includes a bore by milling through a wall of the bore and drilling through a subterranean formation.
  • a liner assembly that extends through a junction between the bore and the lateral bore is installed.
  • the liner assembly includes a body and an isolation mechanism exterior to part of the liner body in the bore.
  • the subterranean formation that is proximate to at least part of the lateral bore is fractured using fracturing pressure.
  • the liner assembly isolates the junction from the fracturing pressure. At least part of the liner assembly is retrieved prior to completing construction of the well system for production.
  • a wellbore assembly that includes a whipstock, a liner body, a first isolation mechanism and a second isolation mechanism.
  • the whipstock can direct drilling tools for creating a lateral bore in a subterranean formation at a junction with a bore.
  • the liner body can extend through the junction and the lateral bore from the bore.
  • the first isolation mechanism and the second isolation mechanism can cooperate with the liner body in isolating the junction from fracturing pressure for fracturing the subterranean formation that is proximate to part of the lateral bore.
  • the first isolation mechanism is exterior to part of the liner body that can be in the bore.
  • the second isolation mechanism is exterior to part of the liner body that is in the lateral bore. At least part of the liner body is retrievable from the well system prior to construction of the well system being completed for production.

  • Certain aspects and features relate to isolating a junction 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.

  • a casing exit can be milled out of a first bore and the lateral bore created by drilling to a desired depth or location.
  • a liner can be run into the lateral, such as across a whipstock or by using a bent joint, and a retrievable packer can be set in the first bore closer to the surface than the window in the first bore for the lateral bore.
  • the portion of the liner in the lateral bore can include any and one or more of a swell packer, stimulation sleeves, cementing equipment or packers.
  • the liner including certain components, can isolate the junction from pressure from fracturing stimulation performed in the lateral bore subsequent to the liner being run.
  • At least part of the liner can be retrieved (i.e. removed from the wellbore) prior to the wellbore being completed to regain flow from below the junction.
  • the entire liner is retrieved.
  • part of the liner is retrieved and another part remains in the wellbore system.
  • the liner or part of the liner can be retrieved by various methods and using various devices and mechanisms.
  • the liner includes a mechanical and / or hydraulic disconnect mechanism that can be located in part of the liner that can be in the lateral bore.

  • a cutting tool that includes a mechanical or chemical cutting mechanism is run downhole using wireline, coiled tubing, or another running tool.
  • the cutting tool can enter an internal bore defined at least in part by the liner.
  • the liner can respond to the cutting mechanism be disconnecting and being retrieved.
  • Some aspects of the liner include a profile on an inner wall that can receive part of the running tool to allow the running tool to be run to the proper location.
  • the whipstock (if used) can be retrieved to regain access to the first bore.
  • Certain aspects can save rig time in comparison to previous junction isolation techniques by reducing the number of trips downhole to isolate the junction and by reducing the complexity of completing a fracture stimulated multilateral junction. Certain aspects can avoid the use of seals for pressure integrity and can facilitate a greater pressure isolation rating.
