Research interests

I am working with Professor Olivier Dubrule, Dr Cédric John and Dr Gary Hampson on geostatistical methods applied to carbonate outcrops and carbonate reservoirs.

For the first year of the project we focused on modelling statistical asymmetries between facies. It was indeed observed that facies tend to be agenced in shallowing upward parasequences: subtidal, intertidal to supratidal. In the geostatistical literature, only Markov chain based methods are able to model such sequences but are limited to exponential covariances. Therefore, we have created a method based on Pluri-Gaussian Simulations able to create cross asymmetries between facies by using a spatial shift between the gaussian functions. Paper and code soon available ! 

We are now looking at extending the method for more than three facies and using a wider range of variogram models. 

Conference paper for stressing the importance of asymmetry (IPTC 2016):

Paper published in Geostats Valencia 2016 for the analysis of asymmetric transiograms derived from Pluri-Gaussian simulations:

Here is some work in which we try to relate experimentally the facies thicknesses pdf and the indicator variogram:
