Abstract
Disclosed herein are methods, systems, and devices for determining parameters of an earth formation. Pressure transient data from a formation test can be recorded and analyzed using an analytical model including one or more correction factors derived from an assumption that an induced flow within the formation is hemispherical. Regression analysis of the refined analytical model and the pressure transient data results in accurate earth formation parameters.
