The Influence of Reservoir Clay Composition on Heavy Oil In Situ Combustion

Thermally enhanced oil recovery methods, such as in situ combustion and steam injection, are generating considerable interest terms of improving reserve exploitation satisfying demand economic growth. However, the early breakthrough front significant amount heat loss associated with injection for deeper reservoir applications main challenges that require urgent solutions. Further data collection related to effects a reservoir’s physical chemical properties, temperature, pressure on propagation transfer inefficiency would be needed achieve better recovery. Most studies have focused application catalytic systems investigation minerals’ stabilization; however, effect clay interlayers’ minerals performance is still poorly understood. This paper takes new look at role played by stabilizing using X-ray diffraction (XRD), thermogravimetry (TG), differential scanning calorimetry (DSC) combined nuclear magnetic resonance (NMR), tube experiments. The studied samples’ compositions were analyzed XRD, TG/DSC, NMR techniques. Meanwhile, production screened obtained from this study suggest dispersion within improve via combustion, our led us obtain an 80.5% factor. experiments models interlayers showed less factors, model 0% factor presence air injection. same hydrothermal conditions 13.9% was due permeability pore enlargement, which allowed matter. Moreover, found exhibit excellent formation fuel deposition coke oxidation process. reflected decreasing number heteroatoms breaking down C-S, C-N, C-O bonds stimulating processes hydrocarbon polymerization during combustion. Our results add growing body literature underline importance parameters successful
