three-dimensional models of reservoir properties including oil and gas saturation in
strata (Fig. 15.6). The model allows to see and analyze:
correlation relationships between parameters (porosity, oil saturation)
spatial heterogeneity of reservoir properties
lithological heterogeneity of the reservoir formation
geological patterns.
The model of the spatial distribution of reservoir properties (porosity, permeabil-
ity, oil saturation) is one of the key components of a computerized 3D model of the
oil field. The model is a key for correct estimation of initial geological reserves and
for obtaining correct results in hydrodynamic modeling.
Also, the main result of the created 3D geological model is the ability to calcu-
late the initial geological reserves of oil and gas.
