Patent ID: 8215395

Claim:
A well treatment method for squeezing and gravel packing, comprising; running in an outer assembly that comprises a packer, an outer string supported by said packer and leading to at least one screen and further comprising at least one outer exit port between said packer and said screen; supporting said outer assembly with an inner string assembly for run in where the inner string assembly is in turn supported on a running string and the inner string assembly comprises a crossover tool to selectively allow gravel to pass through the inner string and out toward said outer exit port of said outer assembly with returns coming through said screen and said crossover tool to an upper annulus defined above said packer and around said running string; setting said packer to isolate a zone in a wellbore for said screen, said set packer defines said upper annulus located above and further defines a lower annulus located below and around said screen; defining a squeeze position for forcing fluid into the wellbore through said lower annulus, a circulate position where gravel is deposited in said lower annulus and returns come through said screen and past said packer to said upper annulus and a reverse position where gravel in said inner string above said crossover can be reversed out to the surface, by relative movement of at least a portion of said inner string with respect to said packer; moving said inner string assembly to a supported single position on said outer assembly; manipulating a ported valve assembly with said running string to selectively close or open said upper annulus from said lower annulus for said squeeze and circulate positions respectively while said inner string assembly remains supported in said single position.
