The Smokey Hill Chalk section of the Niobrara Formation has historically presented problems using conventional stimulation techniques. The Niobrara Formations is a very porous, poorly consolidated micrite. Its high porosity and fracture permeability contributes to its fairly low rock embedment strength and its tendency toward fluid imbibition. A moderately high clay content also is evident. A discussion of formation analysis, drilling program, and conventional stimulation treatment is presented. Stable foam fracture treatments using 6,260 gal of 2% potassium chloride water for a final volume of 31,300 gal of .80 quality foam carrying 32,000 lb of sand has proven to be superior to past treatments. A more recent improvement has been the elimination of 50% of the water with the substitution of 3,130 gal of methanol. Thus, all of the advantages of an alcohol based fracturing fluid are obtained, while at the same time keeping the fluid content and cost increase down to a minimum.
