    Oct 2016

    In “How green is my oil?” by Azzolina et al., the authors presented an integrated life-cycle model for CO2-EOR where the CO2 is sourced from a coal-fired power plant. The model was developed entirely in Microsoft Excel® to improve transparency and provide a useful tool for other practitioners. This model is an updated version of the model from the article. The cells have been unlocked so they can be modified.
