Uncertainty analysis for the determination of permeability and specific storage from the pulse-transient technique

Abstract

and k ofsamples in the laboratory e.g., [1–8]. Most methods are based onfluid flow during stabilized conditions in a closed flow system(e.g., oscillating pore pressure, linear pressurization, and constant-rate flow injection methods) [3–8]. One major disadvantage ofthese approaches is the long duration of experiments required forhydraulically tight specimens; the initial transient stage necessi-tates experiments of weeks duration in some cases. Because of itsrelative expediency, the pulse-decay technique for determining β
