Inversion of Electrical Resistivity Data: A Review
High density electrical prospecting has been widely used in groundwater investigation, civil engineering and environmental survey. For efficient inversion, the forward modeling routine, sensitivity calculation, and inversion algorithm must be efficient. This paper attempts to provide a brief summary of the past and ongoing developments of the method. It includes reviews of the procedures used f...

The Block Conjugate Gradient for Multiple Right Hand Sides in a Direct Current Resistivity Inversion
In geophysical applications direct current (DC) resistivity surveys are collected by injecting current and recording voltage potentials over a field site of interest. These data sets can provide valuable non-invasive images of the sub-surface. The optimization problem that arrises in producing these images requires multiple solves of a linear system with numerous right hand sides (RHSs). Due to...
متن کاملThree-dimensional numerical modelling and inversion of magnetometric resistivity data
We develop an algorithm to model magnetometric resistivity (MMR) response over an arbitrary 3-D conductivity structure and a method for inverting surface MMR data to recover a 3-D distribution of conductivity contrast. In the forward modeling algorithm, the second-order partial differential equations for the scalar and vector potentials are discretized on a staggered gird using the finitevolume...
متن کاملJoint inversion of borehole electromagnetic and sonic measurements
New-generation electromagnetic (EM) and sonic logging tools are capable of measuring multi-frequency multi-component data at multiple depths of investigation. This allows us to image the formation around the borehole by using an inversion method. A method is developed for directly obtaining porosity and fluid saturation distributions by simultaneously inverting borehole EM and sonic measurement...
