Reconstruction of fractured reservoirs

The goal of this project is to provide a set of rules to predict the type and spatial organization of discontinuity networks (e.g., fractures, dissolution features, stylolites, and bedding surfaces) in subsurface reservoirs. This is needed to populate mechanic and flow models of targeted reservoirs.

The first part of this project covers the characterization of fractures and large scale dissolution features in outcropping analogs. Two main expeditions have been performed and data is currently being analyzed. The main findings of this part will lead to a better understanding of the spatial distribution of these discontinuity networks and will improve the realism and accuracy of our static geological models.

The second part of this project covers the numerical simulation en reconstruction of the aforementioned large scale dissolution features. We have developed a numerical code which solves fully coupled reactive-transport in fractured porous media. Currently, we are adding thermal effects to the numerical simulation framework and validating our results. Ultimately, this allows us to inter- and extrapolate our findings in the first part of this project and further improve the realism and accuracy of our static geological models and subsequent uncertainty quantification.
