Touching-Vug Reservoirs

Abstract

The three-dimensional spatial distribution of petrophysical properties is controlled by two geological processes, depositional and diagenetic. Although it is clear that the three-dimensional spatial distribution of petrophysical properties is initially controlled by the spatial distribution of depositional textures, it is also clear from numerous reservoir studies that the petrophysical properties found in carbonate reservoirs are significantly different from those of modern carbonate sediment. Diagenesis typically reduces porosity, redistributes the pore space, and alters permeability and capillary characteristics.
