peace and hotep,

"Drillers use millions of gallons of fresh water which is pressurized to fracture the shale. In some caseds, these haynesville shale operators will use a fresh water/sand combination. This fracturing technique releases the natural gas trapped in the shale but also has the potential to contaminate the water supply."

Hydraulic fracturing technique:
United States Patent 4067389
Inventors:Savins, Joseph George (Dallas, TX)
Application Number:05/705866 Publication Date:01/10/1978 Filing Date:

Claims:I claim:

1. A method of fracturing a subterranean formation penetrated by a well, comprising:
a. injecting down said well and into said formation at a pressure sufficient to fracture said formation a fracturing fluid comprised of a reaction product of an aqueous mixture of a microbial polysaccharide produced by the bacterial action of the genus Xanthomonas and a galactomannan gum obtained from locust bean gum;

b. thereafter injecting down said well and into said formation and fracture, an aqueous solution of a halide salt to contact said halide salt and said fracturing fluid and reduce the viscosity of said fracturing fluid; and

c. backflowing said fracturing fluid and halide salt from said formation and fracture into said well.

2. The method of claim 1 wherein said microbial polysaccharide and said galactomannan gum are present in said fracturing fluid in a ratio within the range of about 20 percent microbial polysaccharide and 80 percent galactomannan gum to about 95 percent microbial polysaccharide and 5 percent galactomannan gum.

3. The method of claim 2 wherein said microbial polysaccharide and said galactomannan gum are present in about equal amounts.

4. In a method of hydraulically fracturing a subterranean formation penetrated by a well wherein there is injected down the well and into the formation a fracturing fluid under sufficient pressure to form and propagate a fracture into the formation, the improvement comprising:
a. forming an aqueous mixture of a microbial polysaccharide produced by the bacterial action of the genus Xanthomonas and a galactomannan gum obtained from locust bean gum wherein said microbial polysaccharide and said galactomannan gum are present within the range of about 20 percent microbial polysaccharide and 80 percent galactomannan gum to about 95 percent microbial polysaccharide and 5 percent galactomannan gum; and

b. heating said aqueous mixture of microbial polysaccharide and galactomannan gum to a temperature of at least 77 F. to form said fracturing fluid.
