Patent ID: 8230924

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 assembly 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 from said upper annulus and define a lower annulus; 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 assembly above said crossover can be reversed out to the surface, by relative movement of at least a portion of said inner string assembly with respect to said packer; providing, as a part of said inner string assembly, a wash pipe with an open wash pipe valve adjacent a lower end of said inner string assembly; isolating said upper annulus from said lower annulus in said reverse position with without closing said wash pipe valve.
