Structure Mapping at Trap Spring Oilfield, Nevada, Using Controlled-source Magnetotellurics
This article gives a particularly good description of the CSAMT method, a type of CSEM surveying in which the transmitter is placed far field from the receiver. At the time of this article, this field practice was necessary to simplify the mathematics involved in modeling the data but is no longer necessary with modern inversion […]
