ABSTRACT:
A method for determining the relative permeability of an earth formation surrounding a wellbore having a longitudinal axis comprising the steps of injecting a fluid into the wellbore such that the fluid invades the earth formation, measuring at different points in time a quantity that varies in response to the radius from the wellbore axis of the fluid invasion into the earth formation, determining in response to said quantity measurements the radius from the wellbore axis of the fluid invasion into the earth formation, and determining in response to said radii determinations the relative permeability of the earth formation. A system for performing the method is also disclosed.
