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%.

An apparatus and method for removing cuttings in a deviated borehole using drilling fluids. The apparatus includes a pipe string and a bottom hole assembly having a down hole motor and bit for drilling the borehole. The pipe string has one end attached to the bottom hole assembly and does not rotate during drilling. The apparatus and methods raise at least a portion of the pipe string in the deviated borehole to remove cuttings from underneath the pipe string portion.

Method and apparatus for removing cuttings

The present invention provides environmentally safe foamed fracturing fluids, additives for foaming and stabilizing foamed fracturing fluids and methods of fracturing subterranean zones. The foamed fracturing fluids of this invention are basically comprised of water, a gelling agent for forming the water into gelled water and increasing the viscosity thereof, sufficient gas to form a foam, and an effective amount of an additive for foaming and stabilizing the gelled water comprised of hydrolyzed keratin.
