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.

What is claimed is: 1. A well system, comprising: a casing expansion device interconnected in a casing string for initiating at least one inclusion propagated into a formation surrounding the casing string, the expansion device having at least one opening in a sidewall for fluid communication between the inclusion and an interior of the casing string, wherein the casing expansion device receives therein a flow control device which is detached from a conveyance device and fluidly sealed within the casing expansion device on opposite sides of the opening; and the flow control device retrievably installed in the expansion device, the flow control device controlling flow of fluid between the formation and an interior of the casing string. 2. The well system of claim 1, wherein the expansion device includes an internal latching profile for releasable engagement by the flow control device. 3. The well system of claim 1, wherein the flow control device prevents flow of the fluid through the opening. 4. The well system of claim 1, wherein the flow control device regulates flow of the fluid through the opening. 5. The well system of claim 1, wherein the flow control device filters the fluid which flows through the opening. 6. The well system of claim 1, wherein the flow control device includes at least one sensor which senses at least one property of the fluid. 7. The well system of claim 1, wherein the formation comprises weakly cemented sediment. 8. The well system of claim 1, wherein the inclusion is propagated into a portion of the formation having a bulk modulus of less than approximately 750,000 psi. 9. The well system of claim 1, wherein the formation has a cohesive strength of less than 400 pounds per square inch plus 0.4 times a mean effective stress in the formation at the depth of the inclusion. 10. The well system of claim 1, wherein the formation has a Skempton B parameter greater than 0.95exp(−0.04 p′)+0.008 p′, where p′ is a mean effective stress at a depth of the inclusion. 11. A method of controlling flow of fluid between a formation and an interior of a casing string, the method comprising the steps of: interconnecting a casing expansion device in the casing string; expanding the expansion device to thereby initiate propagation of at least one inclusion into the formation; and installing a flow control device in the expansion device to thereby control flow of the fluid between the inclusion and the interior of the casing string, wherein the installing step comprises conveying the flow control device into the casing string via a conveyance device and detaching the conveyance device from the flow control device while the flow control device is received and fluidly sealed within the expansion device. 12. The method of claim 11, wherein the installing step is performed after the expanding step. 13. The method of claim 11, further comprising the step of retrieving the flow control device from the expansion device after the installing step. 14. The method of claim 11, wherein the installing step further comprises straddling at least one opening in a sidewall of the expansion device with seals on the flow control device. 15. The method of claim 11, wherein the flow control device prevents flow of the fluid after the installing step. 16. The method of claim 11, wherein the flow control device regulates flow of the fluid after the installing step. 17. The method of claim 11, wherein the flow control device filters the fluid after the installing step. 18. The method of claim 11, wherein at least one sensor of the flow control device senses at least one property of the fluid after the installing step. 19. The method of claim 11, wherein the formation comprises weakly cemented sediment. 20. The method of claim 11, wherein the formation has a bulk modulus of less than approximately 750,000 psi. 21. The method of claim 11, further comprising the step of injecting a dilation fluid into the formation, thereby reducing a pore pressure in the formation at a tip of the inclusion. 22. The method of claim 11, further comprising the step of injecting a dilation fluid into the formation, thereby increasing a pore pressure gradient in the formation at a tip of the inclusion. 23. The method of claim 11, further comprising the step of injecting a dilation fluid into the formation, thereby fluidizing the formation at a tip of the inclusion. 24. The method of claim 11, further comprising the step of injecting a dilation fluid having a viscosity greater than approximately 100 centipoise into the formation. 25. The method of claim 11, wherein the formation has a cohesive strength of less than 400 pounds per square inch plus 0.4 times a mean effective stress in the formation at a depth of the inclusion. 26. The method of claim 11, wherein the formation has a Skempton B parameter greater than 0.95exp(+0.04 p′) +0.008 p′, where p′ is a mean effective stress at a depth of the inclusion.
