Sensitivity Analysis to Investigate Possibility of Steam Injection in an Iranian Carbonate Heavy Oil Field

Steam injection in naturally fractured heavy oil reservoirs provides an extremely challenging problem as<br>well as a potentially effective and efficient improved oil recovery method. Coupling of the two distinct and<br>contrasting matrix and fracture systems results in a highly non-linear problem, and it gets even more<br>complicated as a result of steep changes in fluid properties due to the thermal effects of steam injection.<br>Modeling and designing an optimum steam injection operation in such systems requires an accurate<br>characterization and representation of a naturally fractured heavy oil reservoir and steam injection<br>operation parameters and dynamics.
