Combustion tube experiments are conducted in the laboratory to determine the burning characteristics of a particular oil in a rock matrix. These characteristics include fuel laydown, air-fuel ratio, H/C ratios and the adiabatic combustion temperature. The combustion tube experiment can then be numerically modeled so that a suitable reaction scheme and other data necessary for field simulation can be determined. The data obtained from history matching the tube experiment cannot be used directly for field simulation. Grid blocks used for a tube simulation are on the- order of inches thick, while grid blocks for a field simulation will be 100 to 1,000 times larger. Also, the estimated kinetics data from a combustion tube history match are time and temperature dependent and will not produce similar results in large grid blocks. This paper outlines a new method of history matching the results of a semi-adiabatic combustion tube experiment and scaling them to a form that can be used for field simulation. The shortcomings of current thermal simulators and the suggested remedies also are discussed in this paper.
