We extend that framework to jointly invert multiple geophysical data sets that depend on multiple physical properties

Examining and discussing the physics of electrical and EM responses of steel-cased wells, with focus on grounded source methods.

The effects of the background conductivity are investigated; this study shows that a moderately conductive and chargeable target in a resistive host is an ideal scenario for generating strong IP signals

Producing a quasi-geology model that presents good structural locations of the diamondiferous PK unit and can be used to provide a resource estimate or decide the locations of future drillholes.

Applying our framework to inverting airborne frequency domain data, acquired in Australia, for the detection and characterization of saline contamination of freshwater.

Presenting arguments for adopting an open-source methodology for geophysics and provide some background about open-source software for electromagnetics.

Fluid flow in the vadose zone, governed by the Richards equation, requires characterizing hydraulic properties using direct and proxy measurements. We present an efficient inversion technique for 1D, 2D, and 3D hydraulic properties, implemented in SimPEG, enabling large-scale inversions with modest resources.

Identifying some of the opportunities and areas of future research for the use of geophysical data for carbon mineralization.

We use our algorithm to generate an ensemble of solutions with mixed ℓp norms. In addition, we use this ensemble to estimate the suite of p values that can be used in a final inversion.

overview of the software in its application to airborne electromagnetics and demonstrate its use for visualising fields and fluxes in a forward simulation, as well as its flexibility in formulating and solving the inverse problem.

Reflecting on the development of EM geophysics over the years, to enhance understanding of EM geophysics, and on its visibility and usefulness to the community.

Proposing a framework for organizing and implementing electromagnetic simulations and gradient-based inversions in a modular, extensible fashion.

Proposing a framework that supports many different types of geophysical forward simulations and deterministic inverse problems

This article considers the potential for open-source software and open-science practices to accelerate research in applied geophysics and thereby contribute to solutions of geoscientific problems impacting society.

Adopting a cylindrical discretization for numerical simulations to investigate three important aspects of DC resistivity in settings with steel-cased wells.
