The spatial distribution of rock fractures during water injection in hot dry (HDR) geothermal is essential information for evaluating well fracturing. produce anisotropic electrical characteristics, which may facilitate geophysical methods monitoring fracture distribution. This paper studies the magnetotelluric (MT) response fracturing based on finite difference method (FEM). It uses residual p...

S U M M A R Y An inversion algorithm which takes into account the varying geometry in magnetotelluric models is considered. The particular problem of estimating the shape of the interface between two different conductivities is studied. This boundary is represented by an implicit function and its parameters are calculated in the inversion process. The assumption of using such a function allows ...

Magnetotelluric (MT) and audio-magnetotelluric (AMT) studies are sensitive to the geothermal fluids filling faults and/ or fracture zones of system. In India, MT/AMT have been carried out in NW Himalayas, central, eastern, western India. other areas, detailed need be expedited. This review paper presents art exploration India by using techniques identifies potential that can exploited for power...

Design of experiments for discrete ill-posed problems is a relatively new area of research. While there has been some limited work concerning the linear case, little has been done to study design criteria and numerical methods for ill-posed nonlinear problems. We present an algorithmic framework for nonlinear experimental design with an efficient numerical implementation. The data are modeled a...

In some geophysical problems, it is sometimes possible to divide the subsurface resistivity distribution as a one dimensional (1D) contribution plus some two dimensional (2D) inhomogeneities. Assuming this scenario, we split the electromagnetic fields into their primary and secondary components, the former corresponding to the 1D contribution, and the latter to the 2D inhomogeneities. While the...
