Abstract

Summary

petrophysical properties such as porosity and permeability of the reservoir rocks and rock mechanical properties are affected by the relevant physical properties and such physical properties and mechanical properties affect the drilling programs and the development plans for a reservoir. It is more convenient to use homogenous rock samples with nearly constant initial permeability, obtaining such cores is very difficult. In this paper a simulated natural and homogeneous compacted sandstone rock with known physical and petrophysical properties were used. The physical properties include grain size, cementing material concentration, and compaction (confining) pressure. The effect of these properties on the petrophysical properties of Rock such as permeability and porosity were also known. For the same simulated natural sandstone rocks, Sound wave velocity was measured using an ultra sound tool. Good relationships have been developed between sound wave velocity and other rock properties; porosity, permeability, mechanical parameters namely Young, shear modulus and poison’s ratio. This study has been carried out on dry core samples and core samples with different saturations. The results of this study were presented as graphs of simulated lithification factors, porosity, permeability mechanical parameters versus sound wave (compressional and shear) velocity under different degree of water saturation.
