Particular Qualities of the Productive Layer Geological Model Construction for the Reserves Calculation.
In this paper we touch upon the question of geological 3D model construction taking into account a productive layer lithologic shielding. Such a shielding has various natures that influence on the behavior of oil-filled stratum in the interwell space. Thus, oil-filled stratum maps construction requires a certain problem-solving approach to the "attenuation-substitution" of the productive layer.
