Fracturing subterranean formations without damaging the formation
Patent
·
OSTI ID:5130978
A method of fracturing a subterranean formation is described in which the subterranean formation is first fractured with an aqueous liquid containing a material which will adsorb to the organic polymer attracting sites in the formation adjacent to the face of the fracture. This material occupies the organic polymer attracting sites while the gelled fracturing fluid is in the formation adjacent to the face of the fracture; thus, the gelled fracturing fluid is removed from the subterranean formation when the formation fluids are produced. This material has the additional property of being desorbed as the formation fluids are being produced, leaving the interconnecting pore spaces in the formation adjacent to the face of the fracture free from material which could restrict the flow of formation fluids into the fracture.
