1. A method of performing an operation in a wellbore, comprising: installing a permanent sandface assembly at a desired location in a wellbore adjacent to a well zone;positioning a service tool in the permanent sandface assembly; andtransitioning the service tool between circulating flow and reverse flow configurations using a plurality of valves positioned in the service tool, the transitioning being accomplished without moving the service tool with respect to the wellbore. 2. The method as recited in claim 1, further comprising actuating at least one valve of the plurality of valves upon sensing a steady-state condition in the wellbore. 3. The method as recited in claim 1, wherein adjusting comprises adjusting at least three valves via a control module responsive to unique control signatures sent downhole. 4. The method as recited in claim 1, wherein adjusting comprises adjusting at least three valves via a control module responsive to wireless signals sent downhole. 5. The method as recited in claim 1, wherein adjusting comprises adjusting at least three valves via a control module responsive to a pressure signature sent downhole. 6. The method as recited in claim 1, wherein adjusting comprises adjusting at least three valves via a control module responsive to pressure signals on the annulus. 7. The method as recited in claim 1, wherein adjusting comprises adjusting at least three valves via a control module responsive to load signatures on a work string coupled to the service tool. 8. The method as recited in claim 1, wherein adjusting comprises adjusting at least three valves via a control module responsive to electromagnetic signatures sent downhole. 9. The method as recited in claim 1, further comprising confirming a change in the flow configuration upon adjustment of the plurality of valves. 10. The method as recited in claim 1, wherein transitioning comprises shifting the service tool from the circulating flow configuration to the reversing flow configuration. 11. The method as recited in claim 1, wherein transitioning comprises shifting the service tool from the reversing flow configuration to the circulating flow configuration. 12. A method of servicing a wellbore, comprising: coupling a service tool with a bottom hole assembly having a packer and a screen such that the service tool is separable from the bottom hole assembly;directing fluid flow through the service tool via a plurality of valves disposed in a body of the service tool;using the fluid flow to form a gravel pack adjacent to a desired zone within a wellbore;adjusting the configuration of the plurality of valves based on signals sent downhole to a control module on the service tool to achieve a first flow configuration and a second flow configuration during formation of the gravel pack; andupon completion of the gravel pack, removing the plurality of valves from the wellbore with the service tool. 13. The method as recited in claim 12, wherein coupling comprises coupling the service tool with the bottom hole assembly having a GP packer. 14. The method as recited in claim 12, wherein adjusting comprises adjusting the configuration of the plurality of valves to a circulating flow configuration without lineal movement of the service tool relative to the bottom hole assembly. 15. The method as recited in claim 12, wherein adjusting comprises adjusting the configuration of the plurality of valves to a reversing flow configuration without lineal movement of the service tool relative to the bottom hole assembly. 16. The method as recited in claim 12, wherein adjusting comprises adjusting at least three valves based on wireless signals sent downhole to the control module. 17. A system for use in a well, comprising: a service tool to carry out a gravel packing operation while in a permanent completion located downhole in a wellbore, the service tool comprising a plurality of valves mounted on the service tool independent of the permanent completion, the plurality of valves being individually actuatable to transition the service tool between circulating flow and reversing flow during the gravel packing operation independently of the permanent completion. 18. The system as recited in claim 17, wherein the plurality of valves comprises at least three valves individually actuated by a control module within the service tool. 19. The system as recited in claim 18, wherein the control module comprises a sensor to sense a parameter signature sent downhole, the control module being able to adjust the plurality of valves for transitioning the service tool between circulating and reversing configurations. 20. The system as recited in claim 19, wherein the service tool is releasable from the permanent completion to enable retrieval of the service tool and the plurality of valves upon completion of the gravel packing operation.
