Modeling the Effect of Temperature for Enhanced Oil Recovery (EOR) using Steam Injection Technique

Viscosity of crude oil in reservoir hinders the oil flow rate during production, and this factor has been a major problem in crude oil production sectors. In this work, basic mathematical models are developed and simulated using MATLAB to access they models effectiveness towards the evaluation of temperature effects on heavy oil horizontal wellbore, undergoing steam injection EOR. Steam injection temperature of 800 oF (699.817K) and pressure 3 Pa, with other parametric variables, are applied in validating the developed models, to ascertain their dynamic effects on heavy oil reservoir. Results indicate that increase in the temperature of the reservoir through from 100oF (310.928K) to 823.4987oF (712.872K) decreases the heavy oil viscosity from 9.9403 Pa.s 2. 6970Pa.s, hence, enhances flow of fluid from the well. The porosity of 30% using the model developed, shows an increase in the fluid flow velocity from 4.0333*10-6 m2/day to 1.4955*10-5m2/day, while from 3.0250*10-6 m2/day to 1.1216*10-5 m2/day for a porosity of 40%. The results when been compared with other literature results, proves the models developed in this work perfect and valuable as tools for studying steam temperature effects on heavy oils reservoir as an enhanced oil recovery approach, dynamically.
