Forward modeling of magnetotellurics using Comsol Multiphysics
Magnetotellurics is an electromagnetic geophysical method that has been widely used to study structures in Earth's subsurface. Numerical modeling of magnetotellurics is important for survey design, inversion, geological interpretation and many other aspects of geophysical studies. For example, modeling a subsurface conductive body in terms of its conductivity, geometry and dipping angle would y…

Evaluating deep-learning models for debris-covered glacier mapping
In recent decades, mountain glaciers have experienced the impact of climate change in the form of accelerated glacier retreat and other glacier-related hazards such as mass wasting and glacier lake outburst floods. Since there are wide-ranging societal consequences of glacier retreat and hazards, monitoring these glaciers as accurately and repeatedly as possible is important. However, the accur…

Comparison of interpretation uncertainty in spatial domains using portable x-…
Spatial domains defining either geological models or mineral estimation envelopes are among the few components of the mining life cycle that are not quantitatively assessed to communicate uncertainty or error in mineral resource projects. Recent work has investigated the use of Bayesian approximation methods to assess interpretation uncertainty of the classification of drill hole intercepts to …

An interactive sequential-decision benchmark from geosteering
During drilling, to maximize future expected production of hydrocarbon resources, the experts commonly adjust the trajectory (geosteer) in response to new insights obtained through real-time measurements. Geosteering workflows are increasingly based on the quantification of subsurface uncertainties during real-time operations. As a consequence, operational decision-making is becoming both bette…

Stochastic 3D modelling of discrete sediment bodies for geotechnical applicat…
In the course of engineering geological ground characterizations, internal structures of sediments are often simplified to continuous units and structures like lenses are drawn in cross sections based on geologists’ experience. Seeing this as oversimplifications, we propose discrete sediment body (DSB) modelling which is a computational workflow that permits generation of 3D meshes of sedimen…

Efficiency of template matching methods for Multiple-Point Statistics simulat…
Almost all Multiple-Point Statistic (MPS) methods use internally a template matching method to select patterns that best match conditioning data. The purpose of this paper is to analyze the performances of ten of the most frequently used template matching techniques in the framework of MPS algorithms. Performance is measured in terms of computing efficiency, accuracy, and memory usage. The meth…

Statistical levelling of multi-element geochemical data
Regional compilations of multi-element geochemistry can show shifts of level and dynamic range between component surveys, for example when analyses have been made using different laboratories or procedures or at different times. To create a unified composite picture of the geochemistry over a region, some form of relevelling of individual surveys may be needed. Existing treatments have focused …

Quantifying the current state of earthquake hazards in Nepal
Quantitative estimates of present-day earthquake hazard in major cities are essential for effective policymaking, community development, and seismic risk reduction. In this study, we develop a statistical analysis of natural times in Nepal to compute earthquake potential score (EPS) that describes the current level of seismic progression of a city through irregular repetitive cycle of regional …

Probabilistic knowledge-based characterization of conceptual geological models
The construction of conceptual geological models is an essential task in petroleum exploration, especially during the early stages of investment, when evidence about the subsurface is limited. In this task, geoscientists recreate the most likely geological scenarios that led to potential accumulation of reserves in a target block, based on past experience, historical analogues, and interpreted …

Diagrams with multiple metals in CHNOSZ
This paper describes the methods and demonstrates their use to reproduce published Eh–pH and chemical activity diagrams for oxide and sulfide minerals in two bimetallic systems (Fe–V–O–H and Cu–Fe–S–O–H). New logf –pH diagrams are presented to show dissolved species in the Cu–Fe–S–O–H–Cl system and the effects of Fe:Cu ratio on sulfide mineral assemblages.
