Consideration of the geological features of continental deposits during three-dimensional model building

The paper describes the results of Rosneft’s activities in the w estern part of the Maracaibo sedimentary basin which is located in the nor th-west part of Venezuela. The paper presents two methods for creating a geological model for optimizing a waterflooding system and extracting residual oil reserves. Pre-condition for the consideration of few methods is uncertainty because of the strata heterogeneity and lo w resolution of the seismic.

Input data, approach and analysis of results have been considered. Differences in approach and strengths and weaknesses of chosen methods were considered.
