... with nanoparticles can increase the recovery factor up to 5% compared with typical steam injection. However, the oil upgrading achieved in the continuous injection was lower than the one obtained in the core-flooding tests. The numerical model presented in this work, which includes a dynamic nanoparticle retention...

... Physically, the steam injection consists of two sequential phases. In the first phase, the latent heat of vaporization heats up the rock, oil, and irreducible water in the chamber. In the second phase, under the assumption of piston displacement, the heated oil in the chamber is displaced...

... Abstract The thermal recovery method has been applied in to the heavy oil reservoirs in Venezuela for more than 50 years. The cyclic steam injection is the principal thermal technique in Venezuelan heavy oil reservoirs, which has an oil viscosity at reservoir conditions between 600 to 5000 cp...

.... However, permeabilities are usually low, <10 mDarcy, resulting in low gravity drainage production rates with high remaining oil saturation and/or capillary holdup. EOR techniques such as steam injection and miscible gas injection have the potential to improve GOGD rates and recoveries...
