Acoustic and mechanical response of reservoir rocks under variable saturation and effective pressure.
We investigate the acoustic and mechanical properties of a reservoir sandstone saturated by two immiscible hydrocarbon fluids, under different saturations and pressure conditions. The modeling of static and dynamic deformation processes in porous rocks saturated by immiscible fluids depends on many parameters such as, for instance, porosity, permeability, pore fluid, fluid saturation, fluid pre...
متن کاملEffects of temperature and confining pressure on mode II fracture toughness of rocks (Case study: Lushan Sandstone)
The fracture mechanics examines the development and expansion of cracks in solids and how they affect the deformation of materials. The stress intensity factors at the tip of the crack and the critical stress intensity factors or fracture toughness of materials are considered in the relevant criteria. There are three main modes of applying forces to a crack including the tensile mode, shear mod...
متن کاملPermeability of Fractured Media under Confining Pressure: A Simplified Model
An elastic-plastic model was developed to describe the deformation and permeability of fractured rocks under confining pressure. Elastic and elastic-plastic contact models were used in the model to analyze the deformations of a representative element containing a single fracture under various confining pressures. The present work utilized elements from contact mechanics and viscous flows to der...
متن کاملthe study of effect of confining pressure on electrical resistivity of hydrocarbon reservoirs rocks
the electrical resistivity of hydrocarbon reservoir rocks is an important parameters in the calculation of water and oil saturation percent in both carbonate and sandstone reservoir rocks.in this regard, most studies have concentrated on the confining pressure on cementation factor and electrical resistivity in sandstone reservoir rocks. in this study the effect of confining pressure on cement...
متن کاملElastic Properties of Sedimentary Anisotropic Rocks
In multidisciplinary studies carried out in the Budare Oil Field of the Great Oficina Oil Field, there was difficulty matching well log synthetic seismograms with 2D and 3D seismic data. In addition, the seismically determined depths of reservoir horizons are greater than the well sonic log depths. To examine this discrepancy we conducted an experimental study of dynamic elastic parameters of t...
