... ) suggests that there may be productivity benefits to fracturing with PAs over borate crosslinked fluids. Deepwater E&P operators are now developing reservoirs with lower permeabilities (1-20 md) than conventional deepwater reservoirs ( Ostermeier, 1996 ). A few examples include the Wilcox Trend...

... of dynamically-formed filter cakes to clean up from formation faces. Data have been developed for most aqueous fracturing fluid types at temperatures from 100 to 300°F. Of the fluids tested, foams were quickest to clean up followed by uncrosslinked gels and crosslinked fluids, respectively. High viscosity foams...

A laboratory method has been developed to more concisely evaluate the role of the above parameters and data will be presented demonstrating the magnitude of the effects on the time-temperature stability of the crosslinked fluid. Results from both...
