Reservoirs with bottom-hole temperatures in excess of 300/sup 0/F and permeabilities of less than 1.0 md are commonly encountered in drilling and completing geothermal and deep gas wells. Successful stimulation of these wells often requires the use of massive hydraulic fracturing (MHF) treatments. Fracturing fluids chosen for these MHF treatments must possess shear and thermal stability at high bottom-hole temperatures. An increased understanding of fracturing fluid properties has led to the development of a crosslinked fracturing fluid designed specifically for wells with bottom-hole temperatures up to 350/sup 0/F. The specialized chemistry of this fluid combines a high pH hydroxypropyl guar gum solution with a high temperature gel stabilizer and a proprietary crosslinker. The rheologic evaluations employed in the systematic development of this fracturing fluid are described. 13 references.
