In situ combustion of heavy and also light crude oil was successfully propagated in a cylindrical sandstone core, with an adjacent 1mm surrounding simulated fracture, during a series of dry combustion testing using air and 35% oxygen. Combustion peak temperatures up to 830'C were achieved with air, but oxygen utilisation was less efficient than with enriched air. The combustion front was cone shaped as first observed by Schulte and de Vries. The extent of the front tended to increase with increasing combustion peak temperature.
