    摘要: Method for completing a wellbore in a subsurface formation includes providing a sand control device representing one or more joints of sand screens, and a packer assembly along the joints with at least one mechanically-set packer with at least one alternate flow channel therein. Running the packer assembly and connected sand screen into the wellbore, setting a mechanically-set packer into engagement with the surrounding wellbore, injecting gravel slurry into the wellbore to form a gravel pack. An elongated isolation string is run into the sand control device across the packer assembly with valves that serve as an inflow control device. Thereafter, seals are activated around the isolation string and adjacent the packer assembly. A zonal isolation apparatus allows flow control to be provided above and below packer assembly.

    摘要: A sand screen assembly offering alternate flow path technology for gravel slurry is provided. The sand screen assembly utilizes transport conduits along an outer diameter of a base pipe for transporting gravel slurry from sand screen to sand screen, thereby providing for a consistent gravel packing along the wellbore. The assembly also includes a unique in-flow control section. The in-flow control section allows the operator to restrict or control the flow of production fluids into the sand screen assembly once a gravel packing operation is completed. Multiple assemblies may be connected using a unique coupling assembly. A method for completing a wellbore in a subsurface formation using the sand screen assembly is also provided herein.
