TL;DR: In this article, an edge finite-element method was applied to compute magnetotelluric (MT) responses to three-dimensional (3D) earth topography, using a single edge shape function at each edge of hexahedral elements.

TL;DR: In this article, a method for accurately approximating sensitivities is introduced for the efficient 3-D inversion of static-shifted magnetotelluric (MT) data.

TL;DR: In this paper, the authors describe a new method to simulate 3D borehole resistivity measurements at zero frequency (DC) by combining the use of a Fourier series expansion in a non-orthogonal system of coordinates with an existing 2D goal-oriented higher-order finite element algorithm.

TL;DR: In this paper, the authors describe a method to simulate 3D resistivity borehole measurements acquired with alternating current (AC) logging instruments in deviated wells using a non-orthogonal system of coordinates with an existing 2D goal-oriented higher-order self-adaptive hp-finite element (FE) algorithm.

TL;DR: A new numerical method to simulate geophysical marine controlled source electromagnetic (CSEM) measurements for the case of 2D structures and finite 3D sources of electromagnetic (EM) excitation that combines a 1D Fourier transform with a 2D self-adaptive, goal-oriented, hp-Finite element method is introduced.
