The authors examine pressure falloff behavior dominated by storage and skin subsequent to the injection of a non-Newtonian power-law fluid. New solutions to analyze falloff tests are presented in a form suitable for analyzing field data. The effective wellbore concept is used to combine the wellbore storage constant and skin factor. This phase of their work required extensions to the effective wellbore radius concept (for power-law fluids) given in the literature. To improve analysis procedures, they examine the use of the pressure-derivative technique. The authors discuss the advantages of this method for the problem under consideration.
