A procedure was developed by the Bureau of Mines for calculating the amount of oil vaporized or distt(led in the steam zone during steamflooding of an oil reservoir. The results of this procedure are intended to be used with other techniques for calculating oil recovery during steamflooding. Two experiments were conducted in which steam was injected into an oil-saturated, sand-packed tube to investigate oil vaporization by steam. In these experiments, the amount of vaporization of oil by steam is directly related to the amount of steam contacting the immobile oil. Calculations presented in this report indicate that oil vaporization during steamflooding increases as the volatility of the oil and as the steam temperature increases, but decreases as the steam-injection rates increase. Recoveries calculated by this procedure are conservative when compared with other laboratory experiments which included the effect of gas drive and solvent extraction.
