Areal heterogeneity and Sweep Efficiency:
Areal-heterogeneity used in the estimation of Volumetric Sweep Efficiency is almost an unknown?
Whether logging and coring appraisal wells will ever permit direct observation of ‘Areal-heterogeneity’?
Whether ‘Inter-layer heterogeneity’ (refers to the differences in the geological factors that control the concentration and flow of subsurface fluids between formations) and ‘Intra-layer Heterogeneity’ (refers to the comprehensive geological factors that control and influence the vertical flow and distribution of fluids within a single sand layer, mainly including particle rhythm features, bedding structures, permeability rhythms, ratios of vertical to horizontal permeabilities, permeability heterogeneity, and distribution frequencies and densities of muddy bands) can be coupled in order to interpret the ‘Areal heterogeneity’?
Any field-scale advancement in capturing the areal changes of the geological factors that control oil-layer distribution and influence the concentration and flow of subsurface fluids, including the geometric shape, size, and continuity of a reservoir formation, the microstructure of a reservoir, and the areal changes of porosities, permeabilities, thicknesses, and effective thicknesses within a reservoir formation?
