Abstract

Electrical anisotropy, defined as the directional dependence of electrical conductivity within a medium, is an important property to consider when interpreting magnetotelluric (MT) data. We propose the use of anisotropic forward modelling to model fluid flow within a geothermal setting.

Forward models provide synthetic MT responses for hypothetical structures which are compared with measured data to obtain knowledge about the subsurface geology of a region.

Comparisons between synthetic and measured data shows anisotropic fluid volumes are acceptable approximations of fluid injected into the crust. As a result, we support the use of anisotropic forward modelling as a means of modelling fluid motion at depth within a fractured geothermal system.
