... wave oil-bearing formation permeability Mechanisms When a fluid saturated porous medium is exposted to elastic vibrations the following waves are dispersed into the medium: ➢ Two longitudinal waves, compression shock and pressure ➢ A lateral shear wave The compressional shock...

... Abstract Archie's empirical law constitutes the basis of quantitative Petrophysics; however, the physical significance of this law is poorly understood. The issue involves substantial uncertainty in oil in place. Similarly, Carman-Kozeny's (C-K) relation is source of several permeability models...

The attained data was used to interpret thermal decomposition, phase transition and mechanical stability of calcium carbonate rocks. Furthermore the effect of gamma irradiation on pertophysical properties of porosity and permeability...

It has been determined that oil layer thickness, perforation thickness, fracture permeability and its orientation, especially horizontal...

... from the use of these materials in hydraulic fracture stimulation operations in the Burgos Basin in northern Mexico; results from offset wells are also presented for correlation and comparison. Production from this basin comes from low-permeability sandstones normally considered tight gas formations...

... Abstract Horizontal well technology has been widely used in developing gas fields. Very commonly, these wells are hydraulically fractured to improve productivity in low permeability reservoirs. A previously developed method, the Distributed Volumetric Source method (DVS), was applied...

...). To date, about 100 jobs have been performed with this system in Mexico to address conformance problems such as: Water coning/cresting. High-permeability streaks. Gravel pack isolation. Fracture shutoff. Casing leak repair. This paper presents an overview of case histories that used OCP...

... is shown to be unlikely, confirming earlier coreflood data. A more likely mechanism for IOR is that vibration squeezes out the oil bypassed by earlier recovery methods, due to reservoir heterogeneity. While it is quite difficult to bring the injection fluids to the low-permeability zones in a highly...

... Abstract Waterflooding for enhanced oil recovery requires that injected waters be chemically compatible with connate reservoir waters, in order to avoid mineral dissolution-and-precipitation cycles that could seriously degrade formation permeability and injectivity. Formation plugging...
