Experimental Study on Production Performance of Two Different Heavy Oils in Venezuela

摘要

Two heavy oil samples taken from different geographical areas, with high viscosities at reservoir pressure and temperature, but with similar macroscopic characteristics (API gravity, Rsi, SARA, etc), have been evaluated using a methodology developed at PDVSA-lntevep to quantify the "foamy characteristics " of the system. The results show substantial differences in the production mechanisms of the two heavy oils studied, not only in terms of PVT behavior but also in terms of the production performance during core depletion tests.
