Abstract
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.
