Abstract
In this work, the steam injection, polymer, biopolymer (animal glue), and surfactant were used to recover heavy crude oil at 150, 200,250, and 300 oC individually and integrated. The results showed that the best recovery was at 300 oC. Several experiments were carried out in the semi-pilot unit to integrate steam injection with polymer, biopolymer, surfactant, and a mixture of them at the same temperatures to investigate the effectiveness of the integration mechanism for improving oil recovery. Steam injection with surface-active agents is one of the most important methods of oil recovery, which aims to recover the remaining crude oil in the reservoirs after the primary production methods. Experimentally it has been shown that, after water flooding, the oil scavenging area can be increased by surfactant steam flow due to the effect of low steam override as well as low interfacial tension between oil and water in the formation. The obtained results indicated that integration methods with steam is a promising method for the EOR (Enhanced Oil Recovery) of heavy crude oil.
