... gives the highest ultimate oil recovery factor, is 0.20 wt% of initial oil in place (IOIP) under 220°C, while the nickel concentration of 0.05 wt% provides the highest recovery factors at the early stages. A lower temperature of 150°C provides a much lower recovery factor than 220°C, which is mainly due...

... to be done in order to develop a practical method for volumes and average saturation determination. The main contribution of this work is the development of a theoretical method to estimate oil recovery factors in karst reservoirs based on the modeling of the geomorphology of caves. According to this model...

... salinity conditions. Design parameters include preflush salinity, preflush viscosity and preflush slug size. The results suggest these parameters correlate differently with oil recovery factor. Introduction With the current growing demand for oil led by major energy consuming countries such as China...
