Journal ArticleDOI
SimPEG: An open source framework for simulation and gradient based parameter estimation in geophysical applications
TL;DR: The goal of this paper is to propose a framework that supports many different types of geophysical forward simulations and deterministic inverse problems, and provide an open source implementation of this framework in Python called SimPEG (Simulation and Parameter Estimation in Geophysics, http://simpeg.xyz).
Journal ArticleDOI
A framework for simulation and inversion in electromagnetics
TL;DR: An object-oriented approach for defining and organizing each of the necessary elements in an electromagnetic simulation, including: the physical properties, sources, formulation of the discrete problem to be solved, the resulting fields and fluxes, and receivers used to sample to the electromagnetic responses are taken.
Proceedings ArticleDOI
3D DC resistivity modeling of steel casing for reservoir monitoring using equivalent resistor network
TL;DR: In this article, a method that treats the earth's conductivity model as a 3D equivalent resistor network (ResNet), and a casing as a parallel-circuit wire conductor, is proposed.
Journal ArticleDOI
Petrophysically and geologically guided multi-physics inversion using a dynamic Gaussian mixture model
TL;DR: In this article, a framework for jointly inverting multiple geophysical datasets that depend on multiple physical properties was proposed. But the formulation was confined to problems in which a single physical property model was sought, with a single geophysical dataset.
Journal ArticleDOI
Modeling electromagnetics on cylindrical meshes with applications to steel-cased wells
TL;DR: The value of being able to explore the behavior of electromagnetic fields and fluxes through examples which revisit a number of foundational papers on direct current resistivity and electromagnetics in steel-cased wells is demonstrated.
