ABSTRACT:
Subterranean fluids are provided that have improved environmental characteristics, and more particularly, subterranean fluids are provided that include a hydraulic cement in an invert emulsion. Methods of using such fluids in subterranean operations also are provided. An example of a method is a method of using a fluid in a subterranean formation. An example of a composition is a fluid comprising a hydraulic cement and an invert emulsion of an oleaginous fluid, a nonoleaginous fluid, and an emulsifying surfactant, wherein the emulsifying surfactant: has an LC50or EC50that is greater than about 10 milligrams/liter with respect toSkeletonema costatum, Acartia tonsa, Scopthalmus maximus(juvenile), orCorophium volutator; and demonstrates a biodegradability of: greater than about 70% biodegradation in 28 days when tested according to method OECD 301A or 301E; or greater than about 60% biodegradation in 28 days when tested according to method OECD 301B, 301C, 301F, or 306.
