... in the narrow combustion front zone (900 °C) but 60 m ahead the temperature is 500 – 600 °C. Rapid desaturation of reservoir water takes place ahead of the combustion front, allowing combustion gases to enter into the colder bitumen layers, thereby creating some oil mobility. Of particular significance...

...% of the model. The first 15 cm of the injection well is preheated using an electric igniter. Enriched air is used for establishing the combustion chamber. After ignition, the combustion front develops near the injection side and progresses forward while laterally limited inside SAGD chamber boundaries. Flue...

... Project since 2006 ( Petrobank 2009 ). THAI process needs high air injection rate and most of air did not participate in the combustion, but was used to push the air toward the combustion front. Moreover, the sweep efficiency decrease as combustion front moves further from the injection well...

... of the reservoir, close to the overburden, through a horizontal well or a number of vertical wells. Fluids are produced from the reservoir through another horizontal well placed near the bottom of the reservoir. In this configuration, the combustion front moves downward in the gravity direction and displaces...

... scales of porous medium heterogeneity on ISC. We probed the effects of pressure, temperature, injection rates and matrix properties on the combustion of Middle-Eastern 19.7° API and a Californian 16° API crude oils. The experimental perspective includes both oil oxidation kinetics and combustion-front...

... independently the amount of CaCO3 and the amount of fixed carbon in the mix. The temperature of the combustion front propagating in this mix was recorded, together with its velocity. The flue gas was analysed. Application Propagating a combustion front through a fixed bed is a way to produce oil and a fuel...

... well near the top of the model, into the SAGD chamber and a combustion front was established around the air injection well. By operating combustion in the depleted chamber, residual oil was mobilized and produced. The oil recovery was increased by more than 20% over the SAGD operation. Initiation...
