Effective use of Relative Permeability and SCALE Data

Effective Use of Relative Permerability & SCAL Data


The use of analytical methods to predict natural reservoir performances is based on simplifications that enable reservoir engineers to apply simple models to describe complex geological structures.

SCAL enables us to allocate chosen relative-permeability and capillary-pressure curves to appropriate blocks in the simulation grid automatically by applying user-defined criteria. The three-dimensional visualization capability provides a quick and effective way of checking the data allocations. Additionally, SCAL has extensive support for end-point scaling.

Special core analysis, SCAL, data are among the most critical reservoir input data for reservoir simulation models. SCAL data has a direct impact on the way fluids are allocated and distributed in the reservoir simulation models, which would directly impact reservoirs’ STOIIP estimation and their distribution. Moreover, it directly affects the performance of secondary and EOR flooding processes, and in turn impacts the accuracy of the oil and gas reserve estimates, and the management of these reserves.
