Abstract

The 6FF40 is a long-used industry-standard tool for the estimation of oil reserves. This instrument can be used to measure the formation resistivity. It is based on the electromagnetic induction principle and uses a symmetrical six-coil antenna array. The Gauss-Laguerre method is used to perform the Sommerfeld integration for obtaining the response of 6FF40 in layered lossy media. The distorted Born iterative method is used to reconstruct the profile from the measurement data. The results show good agreement with those obtained by using other methods.
