MISCIBLE C02 INJECTION: SENSITIVITY TO FLUID PROPERTIES TINGGI FIELD

This report basically discusses the final results of the project of Miscible CO2
Injection: Sensitivity To Fluid Properties at Tinggi Field. Miscible CO2 flooding
is another common approach to enhanced oil recovery in today's field. The gas will
act as solvent, forming a single oil-like liquid that can flow through a reservoir to
other wells more easily than the original crude. The Tinggi field, which is in the
Malay Basin, offshore Peninsular Malaysia, is a fully developed and producing field
in Esso Production Malaysia Inc.'s production sharing contract area. In order to
predict the performance of these fields undergoing miscible flooding using a
reservoir simulation model, there is a need to identify parameters that have
significant effect on the predictions. The most importantparameters would be the oil
properties such as oil density, oil formation volume factor, and oil viscosity. These
properties were manipulated into several cases in order to observe the sensitivity of
these properties to the oil recovery factor. Miscible CO2 flooding simulations for
Tinggi Field using Eclipse 100 software were performed and analyzed and the results
were included in this report. Before running the simulation for the real field,
practices on how to analyze the simulation results has been done. This report
presents the background of study, problem statement, the objective and scope of
study and all the results that has been obtained from the studies.
