Reservoir Characterization Study of an Iranian CarbonateReservoir by SCAL Application Data

This paper contains the SCAL of carbonate reservoir field. It includes the main available data, plots of relative permeability, capillary pressure, water saturation etc. The plots, analysis of Jfunction versus normalized water saturation and the relations applied for these analyses constitute another section. The main objectives of this paper are: Better understanding of the behavior and characteristics of the reservoir by integrati ng results using these results to characterize the carbonate reservoir properties. The main reservoir characteristics will include: Capillary pressure vs. water and gas saturation, Oilwater relative permeability vs. water saturation, Oilgas relative permeability vs. gas saturation The SCAL module in ECLIPSE is a tool to help engineers effectively use laboratory derived relative permeability and capillary pressure measurements in reservoir simulation. The program has facilities to: Import laboratory data, Perform quality control (such as curve smoothing), Group data according to litho logical parameters and endpoint values, Transform the laboratory data into rock curves suitable for input to simulators Such as ECLIPSE and automatically assign these curves to grid cells (according to a set of user defined rules, for example as a function of porosity, permeability or litho logical parameters).
