Probabilistic Ground Modelling for Offshore Windfarm Sites Based on Geostatistical Simulation

Subsurface

Sparse 2D seismic data leave gaps that deterministic interpolation can't fill. This study builds a 3D probabilistic ground model instead from multiple geostatistical realizations.

Probabilistic modeling of lateritic nickel mineral resources

Mining

This study, co-authored by Geovariances, presents a unified probabilistic workflow for lateritic nickel resource modeling that combines unfolding, plurigaussian simulation, multivariate imputation, and PPMT within Isatis.neo. Applied to...

Spatial uncertainty quantification of extreme cold temperature return periods in Quebec using multivariate turning bands simulation

Subsurface

How likely is a -40°C event in northern Quebec over the next decade? This study, co-authored by Geovariances, answers with numbers instead of guesses — using a five-step...

Applicability of predicted cone penetration test profiles from geostatistical co-simulation on deterministic and probabilistic monopile foundation design for offshore wind turbines

Subsurface

Geotechnical site investigations are costly and often unavailable at every planned turbine position. This study, co-authored by Geovariances, shows how combining CPT data with seismic information through geostatistical...

Probabilistic Modeling of Hourly Precipitation Jointly with ERA5-Land: Application of Geostatistical Simulations

Subsurface

Rain doesn't fall evenly, and sparse weather station coverage makes it hard to forecast. This study, by Geovariances and Hydro-Québec, splits the problem into "does it rain" and...

Stratigraphic and Geotechnical Modelling by Geostatistics, Applied to Penetrometer and Menard Pressure-Meter Tests

Subsurface

Geotechnical parameters like CPT resistance depend on which stratigraphic layer they sit in, so modeling them without anchoring to the stratigraphy risks getting both the estimate and its...

Stochastic time-depth conversion of seismic horizons by geostatistical tools to produce probabilistic models of gross rock

Energy

This technical paper presents an integrated stochastic workflow for frontier petroleum exploration, combining geostatistical methods such as Bayesian kriging with external drift and multiple-realization simulation. The approach generates...

Assessing paleo-channel distribution for probabilistic offshore windfarm ground modelling using Multiple-Point Statistics

Subsurface

Buried paleo-channels are a hidden hazard for offshore wind turbines, invisible between sparse 2D seismic lines, but capable of undermining foundation stability. This study compares multiple-point statistics (using...

Comparison of different prediction methods to derive synthetic CPT profiles – an offshore wind farm case study from the German North Sea

Subsurface

Which method actually predicts soil strength best between widely spaced CPTs? This study, co-authored by Geovariances, pits seven methods — from simple inverse distance weighting to kriging variants...

Coherent modeling of mineral grades and zones by coupling cokriging and Support Vector Machine

Mining

This technical paper explores the complementary use of geostatistics and machine learning for mineral resource modeling, particularly when complex categorical variables make traditional geostatistical workflows difficult to manage....

Using multiple-point geostatistics for geomodeling of a vein-type gold deposit

Mining

Vein-type gold deposits are notoriously hard to model: narrow, long-range structures with sparse drill-hole data defeat conventional two-point geostatistics. This study from Nazarbayev University and the University of...
