Abstract

A method for calculating transmissibility, pore pressure, permeability and/or other properties of a subsurface layer comprising the modeling of the borehole pressure recorded from the time the subsurface layer is fractured by isolating said subsurface layer with a downhole tool, pumping fluid into the subsurface layer and stopping pumping said fluid once the formation is fractured until a pseudo-radial or pseudo-linear flow is reached. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
