Abstract
A method of measuring a parameter characteristic of a rock formation is provided, the method including the steps of deploying in a section of a well penetrating the rock formation a toolstring combining a tool for generating and measuring responses to a sensing field at different radial depth shells in the rock formation relative to the well and a tool to cause a flow of fluid through the different radial depth shells such that responses to the sensing field are obtained for at least two different radial depth shells and for at least two different flow conditions in said at least two different radial depth shells to determine a radial depth dependent profile of said parameter.
