摘要: A process for reducing the viscosity of fracturing fluids in downhole oilfield operations is provided. The process comprises contacting a sulfamate stabilized, bromine-based breaker with an aqueous polysaccharide fracturing fluid, with the breaker present in an amount to reduce the viscosity of the fracturing fluid. A composition which comprises a sulfamate stabilized, bromine-based breaker for use in decreasing the viscosity of an aqueous polysaccharide fracturing fluid for use in subterranean oil and gas wells is also provided.

摘要: Processes for effecting biocidal activity in subterranean oil and gas wells being drilled, completed, worked over or produced are described. In general the process comprises blending with aqueous well fluid a biocidally-effective amount of a sulfamate stabilized, bromine-based biocide. Compositions comprised of aqueous well fluid blended with such aqueous biocides are also described.

摘要: Disclosed are compositions having utility as well fluid base oils. The base oils are comprised of a mixture of internal predominantly linear tetradecene (C14) isomers and internal predominantly linear hexadecene (C16) isomers. The base oils of this invention have pour point temperatures lower than −25° C. and are environmentally acceptable to marine life. The base oils disclosed are ideal candidates for use in cold climates and for offshore drilling.
