New article published: Mineral Interfaces and Oil Recovery: A Microscopic View on Surface Reconstruction, Organic Modification, and Wettability Alteration of Carbonates

https://dx.doi.org/10.1021/acs.energyfuels.0c00118

The surface morphology and composition of calcite (a model substrate for carbonate oil-reservoirs) gets strongly modified when calcite gets exposed to brine and crude oil at 95oC. Reconstruction of the inorganic mineral and adsorption of organic compounds occur in concert. Various types of microscopy are used to characterize the changes. Work performed in collaboration with Aramco.(“Nanocarbonate” project)
