Congratulations to Mrs. Natasa Dollari for the defense of her MSc thesis in Petroleum Engineering at the Technical University of Crete under the supervision of Dr. Christos Chatzichristos and myself. Natasa did a great job in developing a novel Black-Oil Reservoir Simulator in the framework of Partial Differential Equations Module of the Comsol Multiphysics numerical platform. She successfully applied this model for the simulation of Water-Flooding and Water-Alternating-Gas oil recovery scenarions in the “classic 5-spot” reservoir configuration, and compared her results with those of the ECLIPSE 100 simulator. Her thesis is available through this link.
