Abstract
A method for characterizing subsurface formations penetrated by a wellbore includes accepting as input to a computer measurements of a physical parameter of the formations made over a selected axial interval of the wellbore. At least one attribute of the measurements is determined from a change in the measurements over the selected axial interval. At least one characteristic of the formations in the selected axial interval using the at least one attribute.
