Abstract
Gelled oil base compositions useful in the fracturing of subterranean formations are prepared by incorporating aluminum salts of one or more oxaalkyl phosphates and/or oxaalkyl alkyl phosphates in an oil base fluid. The salts can be formed separately followed by addition of the salt to the oil, or the salt can be formed in situ by separately adding to the oil, the phosphoric acid ester and an aluminum compound which then react to form the salt. In the usage of these compositions for fracturing a subterranean formation, the composition is pumped into an oil or gas well, and from the well bore into the formation to form and propagate a fracture in the formation.
