The paper presents an algorithm to generate sphere packing. Produced packing honors complex geological structural and stratigraphic discontinuities. We demonstrated the ability of the method to create adaptive particle radii in order to reduce the global number of sphere while keeping a precise description of small geological heterogeneities. Packings have been validated both using classical statistical metrics from the literature and solving uniaxial and triaxial mechanical simulations with Discrete Element Methods.

In this paper, published in Interpretation, we present an implicit method to automatically generate several possible models of salt top surfaces with varying geometries and topologies. This method can be conditioned to available data such as well markers and seismic picks.

In this paper, published in Hydromettalurgy, we investigate indirect in-situ bioleaching as an alternative mining technology for minimizing waste production, environmental impact, and chemical consumption. Laboratory column experiments are described and their results are used to develop a one-dimensional reactive transport model based on PhreeqC software. This model is then adapted to in-situ conditions by considering the preferential flow of fluids through natural or artificial fractures of enhanced hydraulic conductivity.

In this paper published in Computers & Geosciences, we present OM-MADE, an open-source solution to help a first analysis and simulation of long tail multi-peaked Breakthrough curves observed in karstic systems. OM-MADE (One-dimensional Model for Multiple Advection, Dispersion, and storage in Exchanging zones) is an open-source Python code available on the Github platform : https://github.com/OM-MADE/OM-MADE . The capacities of the software to combine dual-advective-dispersive flow and interaction with immobile water along a flow path discretized into several reaches is demonstrated on the Furfooz area (Belgium).

Geological Objects and Physical Parameter Fields in the Subsurface: A Review

This open-access paper reviews some practical and theoretical frameworks which exist to translate geological concepts into three-dimensional models. The bottomline is that geological parameterizations of subsurface objects offer new ways to quantify subsurface uncertainties and to reduce it. The links between model topology, geometry and properties are also discussed.

In this new paper published in Marine and Petroleum Geology (i) we propose a geometrical and descriptive approach to stochastically control the channel stacking patterns; (ii) we demonstrate trhrough quantitative metrics that this method makes it possible to control the connectivity between the channels by adjusting the geometry of the migrating areas.
