Patent ID: 7040405

Claim:
A method of fracturing a subterranean formation comprising the steps of: preparing a permeable cement composition comprising a hydraulic cement, graded sand, a diluent and an effective amount of surfactant wherein the surfactant is selected from the group consisting of: (a) RO(CH 2 CH 2 O) n R′ where R and R′ are alkyl groups and n is an integer in the range of about 5 to about 50; (b) RPhO(OCH 2 CH 2 ) m OH, wherein R is an alkyl group having from about 5 to about 30 carbon atoms, Ph is phenyl and m is an integer in the range of from about 5 to about 50; (c) R 1 (OR 2 ) n SO 3 X, wherein: (i) R 1 is selected from the group consisting of: a. alkyl groups having from 1 to about 30 carbon atoms; b. cycloalkyl groups having 5 or 6 carbon atoms; c. C 1 –C 4 alkyl substituted cycloalkyl groups, phenyl, alkyl substituted phenol of the general formula (R 3 ) a Ph—, wherein Ph is phenyl, R 3 is an alkyl group having from 1 to about 18 carbon atoms and a is an integer of from 1 to 3, and phenyl-alkyl groups wherein the alkyl groups have from 1 to about 18 carbon atoms and the phenyl-alkyl groups have a total of from about 8 to about 28 carbon atoms; (ii) R 2 is a substituted ethylene group of the formula —CH 2 CH 2 R 4 , wherein R 4 is selected from hydrogen, methyl, ethyl or mixtures thereof; (iii) n is a number from 0 to about 40 provided that when R 1 is phenyl or alkyl substituted phenyl, n is at least 1; (iv) and X is any compatible cation; (d) R 5 —Ph(OR 6 ) o SO 3 X, wherein R 5 is an alkyl radical having in the range of from 1 to about 9 carbon atoms. R 6 is the group —CH 2 CH 2 —, o is an integer from about 10 to about 20 and X is a compatible cation; (e) R 7 (OR 8 ) p SO 3 X, wherein R 7 is an alkyl group having in the range of from about 5 to about 20 carbon atoms, R 8 is the group —CH 2 CH 2 —, p is an integer in the range of from about 10 to about 40 and X is a compatible cation; and, (f) mixtures thereof; and introducing the permeable cement composition in the subterranean formation under sufficient pressure to create or enhance a fracture in the subterranean formation.
