... Abstract Generally, hydrocarbon reserves are determined by the irreducible water saturation using the volumetric equation of the original oil in place (OOIP), regardless of the initial water saturation in the transition zone and as a result overestimate hydrocarbon reserves. The objective...

... by the test temperature. As the temperature increases, the oil recovery increases, for both methods. At the same temperature, the final oil recovery is equal for water and polymer flooding, showing that the used polymer has not affected the residual oil saturation. However, the polymer flooding was able...

Among the recovery methods applied to heavy oil reservoirs, the most popular is steam injection in its different schemes. Nevertheless, in high initial water saturation environments the thermal...

... to reduced oil viscosity and oil swelling by CO 2 . Overall analysis of results of this study indicate that CO 2 could be beneficial for these heavy oil reservoirs in Mexico, as CO 2 increases recovery efficiency and reduces oil saturation in the matrix of the gas cap. However, optimized planning...

Understanding its distribution across sands is also a critical factor in heavy oil environments. As a resistivity...

... llanos Colombia have been analyzed. An important extra heavy oil accumulation toward the outcrop of main production sands was encountered. The reservoir temperature is low (100°F) so bitumen viscosity is high (>100.000cp). In addition, oil saturation could be lower than is the standard for commercial...
