Simple inversion of time-domain electromagnetic data

Tipo de material: TextoTextoSeries ; Geophysics, 49(7), p.925-933, 1984Trabajos contenidos:

Tema(s): Recursos en línea: Resumen: Presents a simple technique designed to brige the gap between rule-of-thumb interpretations and more rigorous numerical modeling techniques. It uses a single equivalent filament of current to approximate the eddy current distribution induced in a finite discrete conductor. The mathematical expressions for the magnetic field produced by a single current filament are simple enough to implement for both forward and inverse modeling of multiple conductors. The method can be applied directly to data collected over conductors in a resistive environment, or to data which have been preprocessed by first subtracting the effect of a conducting environment. -from Author
