Elastic properties of a reservoir sandstone: a broadband inter-laboratory benchmarking exercise
Low-frequency forced-oscillation methods applied to a reservoir sandstone allowed determination of the Young’s modulus and Poisson’s ratio (from axial loading), bulk modulus (by oscillation of the confining pressure) and shear modulus (from torsionalforced oscillations) for comparison with conventional ultrasonic data. All tests were performed on a common sandstone core sample from an oil reservoir offshore West Africa. The results show a steady increase in ultrasonic velocities and shear...[Show more]
