description 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. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
