ABSTRACT:
A method for determining a formation profile surrounding a well bore includes receiving field log data for the formation and generating a Jacobian matrix responsive to the provided field log data. A quasi-Newton update is used to update the Jacobian matrix for each necessary iteration until a generated formation profile converges with the received field log data.
