摘要： A method of servicing a wellbore in contact with a subterranean formation comprising placing a wellbore servicing fluid comprising a polyuronide polymer within the wellbore, contacting the wellbore servicing fluid with a divalent ion source, and allowing the wellbore servicing fluid to form a gel within the wellbore wherein the divalent ion source is located within the wellbore. A method of servicing a wellbore in contact with a subterranean formation comprising (a) placing a wellbore servicing fluid comprising a polyuronide polymer into the wellbore wherein the wellbore servicing fluid contacts a calcium ion source, (b) shutting the wellbore and allowing the servicing fluid to set into place for a period of time, and (c) repeating steps (a) and (b) until the permeability of a structure within the wellbore is reduced by about 50%.
