Abstract
The invention is concerned with a tool and method for determining a downhole parameter. The tool is located in mud surrounded by a formation and comprising a first electrode spaced at a distance from the formation for measuring a first impedance. There is a second electrode located at a second distance from the formation for measuring a second impedance. There is a processing unit for measuring a difference between the first impedance and the second impedance and wherein the parameter is determined based on the difference.
