  • Determining permeability using formation testing data
    Patent number: 8078403
    Abstract: A method, system and computer program product for determining permeability of an earth formation of a reservoir are disclosed. A method may include: providing formation testing data of the earth formation; defining layering of the earth formation; determining a geological model for each layer; modeling pressure transient in the earth formation by representing pressure transient within a layer using an analytical solution and representing pressure transient between two layers using a numerical solution, the analytical solution selected based on at least one of the respective geological model and data regarding a drilled well of the reservoir, and a parameter of the analytical solution and a parameter of the numerical solution being determined based on the formation testing data; and determining the permeability of the earth formation based on the pressure transient model.
