A geostatistical approach to the simulation of stacked channels

Rongier, G ; Collon, P ; Renard, Philippe

In: Marine and Petroleum Geology, 2017, vol. 82, p. 318-335

Turbiditic channels evolve continuously in relation to erosion-deposition events. They are often gathered into complexes and display various stacking patterns. These patterns have a direct impact on the connectivity of sand-rich deposits. Being able to reproduce them in stochastic simulations is thus of significant importance. We propose a geometrical and descriptive approach to stochastically...

Stochastic simulation of channelized sedimentary bodies using a constrained L-system

Rongier, G ; Collon, P ; Renard, Philippe

In: Computers & Geosciences, 2017, vol. 105, p. 158-168

Simulating realistic sedimentary bodies while conditioning all the available data is a major topic of research. We present a new method to simulate the channel morphologies resulting from the deposition processes. It relies on a formal grammar system, the Lindenmayer system, or L-system. The L-system puts together channel segments based on user-defined rules and parameters. The succession of...

Statistical metrics for the characterization of karst network geometry and topology

Collon, P ; Bernasconi, D ; Vuilleumier, C ; Renard, Philippe

In: Geomorphology, 2017, vol. 283, p. 122-142

Statistical metrics can be used to analyse the morphology of natural or simulated karst systems; they allow describing, comparing, and quantifying their geometry and topology. In this paper, we present and discuss a set of such metrics. We study their properties and their usefulness based on a set of more than 30 karstic networks mapped by speleologists. The data set includes some of the largest...

On the use of multiple-point statistics to improve groundwater flow modeling in karst aquifers : A case study from the Hydrogeological Experimental Site of Poitiers, France

Le Coz, M ; Bodin, J ; Renard, Philippe

In: Journal of Hydrology, 2017, vol. 545, p. 109-119

Limestone aquifers often exhibit complex groundwater flow behaviors resulting from depositional heterogeneities and post-lithification fracturing and karstification. In this study, multiple-point statistics (MPS) was applied to reproduce karst features and to improve groundwater flow modeling. For this purpose, MPS realizations were used in a numerical flow model to simulate the responses to...
