Abstract
The effects of oil and gas saturation on geothermal resource were considered in previous study. However it was assumed that the oil and gas saturations were constant during the development. To this end, the existing volumetric approaches of evaluating geothermal resource were modified by considering the change of oil and gas saturation with time. An oil reservoir from Huabei oil field with moderately high temperature was chosen as an example to apply the modified method. The effects of porosity, oil and gas saturation on the geothermal resource were investigated and the results were compared to the existing approaches.
