Abstract: A technique utilizes a Y-block which is coupled with a lateral tubing string and a main tubing string. The Y-block comprises features which facilitate service and/or production operations. In well applications, the Y-block may comprise a pressure housing and a recessed bypass slot disposed along an exterior of the Y-block. A control line is positioned in the recessed bypass slot to facilitate control functions along the lateral tubing string. The recessed bypass slot enables routing of a control line without forming a splice along the control line. In other applications, the Y-block may utilize additional or other features which facilitate the desired operations.

Abstract: A lateral wellbore completion apparatus may include a flow-through deflector having a deflector face and a junction string that includes a junction block cooperative to mate with the deflector face, a downhole device, and an inductive coupler electrically connected to the downhole device. A method may include anchoring the deflector in a main bore, making-up at the drilling surface a junction string that includes a junction block, a completion string section having a downhole device, and a secondary inductive coupler electrically connected to the downhole device, running the junction string into the main bore, deflecting the completion string section into the lateral bore, and landing the junction block on the deflector face thereby communicatively coupling the secondary and primary inductive couplers.

Abstract: A location and orientation assembly suitable for use in a multi-lateral wellbore may include a coupling portion, an upper muleshoe, a muleshoe spacer and a bottom muleshoe. The bottom muleshoe may connect to the coupling portion through a threaded connection. A method for locating and orienting in a multi-lateral wellbore includes providing a locating and orientation assembly. In the orientation assembly a coupling portion is provided and an upper muleshoe is inserted into the coupling portion. A muleshoe spacer is inserted into the coupling portion so as to matingly contact the upper muleshoe portion. Part of a bottom muleshoe is inserted into the coupling portion so as to matingly contact the muleshoe spacer. The coupling portion is jointed to the bottom muleshoe by a threaded connection.

Abstract: Cementing takes place after a hanger and seal are set to first insure the pressure integrity of the connection between the string to be cemented and the existing tubular. Cementing top down or bottom up is envisioned with either displaced fluid returning toward the surface in a crossover tool or with the displaced fluid squeezed into the formation. A work string manipulates the crossover for reversing out after cementing. For running in a valve assembly is held open to permit circulation. Work string manipulation allows at least one valve that keeps the cement in the annulus to close and at least one other valve to close that keeps the reverse fluid from leaving the cemented tubular to allow such flow to return to the crossover and out to the surface. Valve release can be done with a pressure responsive sleeve instead of a stinger on the running string.

Abstract: An apparatus that is usable with a well includes an assembly, which includes a whipstock and a lateral deflector that are adapted to be run downhole into a first wellbore of the well as a unit. The whipstock is adapted to guide at least a drilling string to form a second wellbore, and the lateral deflector is adapted to guide a liner during installation of the liner into the second wellbore.

Abstract: A method of running a first tubular within a second tubular includes running the first tubular into the second tubular past at least one lateral extending from the second tubular, running a diverting tool at the first tubular with the running of the first tubular, withdrawing the first tubular from the second tubular until an end of the first tubular is beyond a junction between the at least one lateral and the second tubular and, running the first tubular into the at least one lateral.

Abstract: A system for production of petroleum from an earth formation. The system includes: an injection assembly disposable within a first borehole for injecting a thermal source into the formation, the injection assembly including an injector extending from a distal end of the assembly; and a production assembly disposal within a second borehole for recovering material including the petroleum from the formation, the production assembly including a collector extending from a distal end of the assembly. At least one of the injector and the collector includes at least a first conduit and at least a second conduit concentric with the first conduit, the first conduit having a first distal end and the second conduit having a second distal end, the first and second distal ends located at different locations along a length of at least one of the first and second borehole.

Abstract: A stand-alone frac liner that allows for fracturing of multiple lateral legs of a multilateral well on a single call out and rig-up of fracturing equipment. Tools and techniques are provided that include setting multiple stand-alone frac liners in multiple lateral legs of the multilateral well. The liners may rest in the legs physically untethered to surface equipment. Thus, a single call out of a frac string tubular and associated equipment may be used to frac the lateral legs in sequence from one leg to the next. This may be achieved without the requirement of removal of the tubular from the well or disconnect of surface fracturing equipment between the lateral fracture applications. Thus, a considerable amount of expenses associated with time and manpower may be saved.

Abstract: An isolation packer. The packer is both an inflation packer and swell-based. That is, an outer shell or bladder may be utilized in conjunction with internal swell material. In advance of inflation, a void or cavity may be disposed between the inner surface of the shell and an outer surface of the swell material. Thus, fluid inflation of this void may result in an inflation that becomes swell-material filled until the void is eliminated leaving behind a more unitary and swollen packer of enhanced reliability.
