In-Situ Combustion is one of the most important and promising methods for enhancing oil recovery for both light and heavy crude oils from reservoirs. In this method air is injecting into the oil reservoirs and causes ignition and in the next step it effects combustion inside of reservoirs. Nuclear Magnetic Resonance (NMR) spectroscopy as a fast and accessible technique was used to monitoring the light and heavy crude oils oxidation behavior. Herein, we investigated two light and heavy crude oils based on temperatu...

Metal-based catalysts have shown promising applications and effects in different thermal enhanced oil recovery (THEOR) to improve oil recovery from oil reservoirs. Also, catalysts were chosen due to their exclusive properties, such as high surface area to volume ratio, high degree of dispersion in porous media and high catalytic activity. This study is aimed at developing a catalytic-enhanced oil recovery for heavy crude oil using in-situ combustion method in the presence of catalyst. In order to that, we synthesi...
