Abstract
Apparatus and methods of treating a subterranean formation including introducing a coiled tubing string into a wellbore to a lowest wellbore zone, wherein the string comprises a single packer on a bottom hole assembly; setting a packer at the lowest zone; introducing an acid fracture treatment through the string at a single zone; introducing bridging fluid comprising polyacid particulates through the string; reducing fluid injecting to unset the packer; circulating a portion of fluid in the wellbore while moving the string in the wellbore; introducing a final portion of fluid with a higher concentration of polyacid particulates to further bridge packer formation and consolidation wherein the concentration of particulates in the final portion of fluid is higher than when introducing bridging fluid comprising polyacid particulates through the string; squeezing the bridging fluid to isolate a perforation into the zone; moving the string to next zone; and repeating introducing and moving.
