A Formula for the Coefficient of Thermal Expansion of Crude Oils

PU Ohirhian

Abstract


A new formula for the calculation of the coefficient of world crude oils has been developed. The formula is semi theoretical. The empirical part was obtained by regression calculation of the Formation Volume Factor of the gas free crude oil at reservoir temperature. Comparison of the calculated values of the Formation Volume Factor of the gas free crude oil with experimental values gave a maximum absolute error of 0.189 %. Thus values of the Formation Volume Factor of the gas free crude oil obtained by the new formula are very close to those that can be obtained by laboratory measurement.
