Method of fracturing formations in wells
Patent
·
OSTI ID:5778633
A method is claimed for fracturing a subterranean formation penetrated by a well bore, the fracturing being accomplished by alternately injecting into the formation a high-viscosity non-Newtonian fluid and a low-viscosity Newtonian fluid, is described. The low-viscosity fluid carries propping agents into the fracture if a wide fracture having a relatively small radius and a layered proppant configuration is desired, and the high-viscosity fluid carries propping agents into the formation if narrow fractures having a relatively large radius and a high permeability are desired.
