Often, when production wells are stimulated by hydraulic fracturing, the fracture
unintentionally breaks into water zones causing substantially increased water production. To
correct this problem, we developed an engineering basis for designing and sizing gelant
treatments in hydraulically fractured production wells. In these treatments, gelant penetrates
a short distance from the fracture face into the porous rock associated with both water and
hydrocarbon zones. Success for a given treatment requires that the gel reduce permeability …
