Abstract
Flow control for increased permeability planes in unconsolidated formations. A well system includes a casing expansion device interconnected in a casing string for initiating an inclusion propagated into a formation surrounding the casing string. The device has at least one opening in a sidewall for fluid communication between the inclusion and an interior of the casing string. A flow control device is retrievably installed in the expansion device and controls flow between the formation and an interior of the casing string. A method of controlling flow of fluid between a formation and an interior of a casing string includes the steps of interconnecting a casing expansion device in the casing string; expanding the device to thereby initiate propagation of an inclusion into the formation; and installing a flow control device in the expansion device to thereby control flow between the inclusion and the casing string interior.
