Abstract Modeling the in situ combustion (ISC) process presence of chemical additives (i.e., catalysts and hydrogen donors) is challenging due to multiple reactions that occur (e.g., hydrocarbon combustion, thermal-cracking, water-gas shift, coke gasification, etc.). The objective this study model numerically catalytic upgrading crude oil using experimental data from Orinoco Oil Belt a generation method available commercial numerical simulator, which will allow considering effect catalyst improving properties providing better understanding mechanisms involved process. ISC tests with (nanoparticles transition metal) donors have been carried out Venezuela for extra-heavy reservoirs Eastern Basin, aiming at stabilization front physical-chemical oil. In article, simulation was based on results tube (pre-packed cells) performed reservoir conditions (8.5 °API, unconsolidated sandstones,4500 cP 50°C) heavy reserves. kinetic used considers upgraded component, as well components. history matching machine learning tool, outputs were applied field upscaling by cluster wells Belt. Experimental show an improvement properties, mainly API gravity viscosity, reduction asphaltene content, high light compounds higher recovery factor greater than 90%. outcome also highlights mineralogy reservoir-rock may An acceptable match variables such API, thermocouple temperature, recovery, gas composition obtained. main production are analyzed illustrated detail. Predictions cumulative production, concentrations, temperature oxygen distributions, sensitivity analyses critical injection rate) evaluated sector presented discussed article. This paper presents workflow modeling Venezuelan highly viscous reservoirs, potential application worldwide. contributes development technologies management acid gases order accelerate energy net-zero carbon 2050.
