A carbon dioxide (CO2) flooding technique is used to extract crude oil. The CO2 floods oil pockets and displaces the crude oil. In the experiment, flow tubes are dipped into sample oil pockets containing a known amount of oil. Using three different values of flow pressure and three different values of dipping angles the oil pockets are flooded with CO2, and the percentage of oil displaced recorded. Consider the model. Fit the model above to the data, and suggest any model editing that may be needed. Source: Wang, G. C. ?Microscopic: Investigations of CO2 Flooding Process,?
