METHOD OF PREDICTING THE RESPONSE OF AN INDUCTION LOGGING TOOL

摘要

There is provided a method of predicting the response of an induction logging tool along an arbitrary trajectory in a three-dimensional earth model, wherein the method comprises a confinement of the electromagnetic field computations to a limited domain of the geology surrounding the induction logging tool. The magnetic field at a receiver coil is considered as a superposition of a primary background constituent and a secondary constituent. A single spherical scatterer approximation is used for the second constituent.
