... porosity of about 16% and permeability of approximately 450 mD. The original formation pressure was in the order of 11,000 psi and the production mechanism is by rock and fluid expansion with bubblepoint in the order of 3,500 psi. Combining these reservoir characteristic with the applied rate...

... Abstract Well-exposed outcrops of Middle Cretaceous carbonates in the Zagros fold belt, Iran have been used to provide input data for a dual porosity reservoir model incorporating both matrix and fracture heterogeneity. The modelled outcrop area is located on the steeper dipping limb of a large...

... of the rock; and, third, because numerical simulation of such reservoirs require reliable values of matrix porosity, fracture porosity, and block size. Naturally fractured reservoirs are complex systems whose flow properties are not well understood. From the fluid transport viewpoint, fractured carbonate...

... injection wells, samples were selected from analogous lithological core sections from adjacent production wells. The density of dry rock, pore volume and effective porosity were determined under surface conditions using techniques recommended by the American Petroleum Institute 3 . The absolute...

Examples of systematic uncertainty include wire-line to core calibration of porosity and saturation. This study also showed that for a specific development scenario the oil in place, gasoil relative...

... that the above assumptions are not representative for these systems. Thus, the fractal theory can contribute to explain the above. The objective of this paper is to investigate the production decline behavior in NFR exhibiting single and double porosity with fractal networks of fractures. The diffusion...

... Abstract The Antonio J. Bermudez basin in Southern Mexico is a low porosity massive Jurassic and Cretaceous carbonate reservoir that is extensively faulted and fractured due to post depositional salt intrusions. The natural fractures create many drilling challenges and obstacles. Underbalanced...

... Fig. 2 shows three additional images of carbonate whole cores. Fig. 2.a illustrates the case of fractures filled by calcite. Fig 2.b presents the important physical condition of fracture planes affected by dissolution, which increases both secondary porosity and bulk permeability. Finally...

... Abstract Permeability, fractional porosities, irreducible water saturation and fluid viscosity calculations, derived from Nuclear Magnetic Resonance (NMR) data, are largely dependant on T2 decay rates (in NMR terminology, T2 is the time constant that characterizes the decay rate of the echo...

Abstract This paper presents the theoretical, experimental, and operational bases of a practical procedure for decomposing total porosity into its basic components, i.e., primary, secondary, fracture, and vug porosities. The procedure makes use of total porosity and formation resistivity factor...
