ABSTRACT:
The present invention provides methods of treating a portion of a subterranean formation, one of which includes: providing a gelled nonaqueous treatment fluid that comprises a nonaqueous base fluid and a difunctional gelling agent that comprises a polyvalent metal salt of a bisorganophosphinic acid, a polyvalent metal salt of a bisorthophosphoric acid diester, and/or a polyvalent metal salt of a bisorganophosphonic acid monoester; and treating the portion of the subterranean formation. Methods of fracturing, providing some degree of sand control, cleaning a portion of a pipeline, treatment fluid compositions, and difunctional gelling agent compositions also are provided.
