Velocity-porosity Relationships, 1: Accurate Velocity Model for Clean Consolidated Sandstones
We use numerical simulations to derive the elastic properties of model monomineralic consolidated sandstones. The model morphology is based on overlapping spheres of a mineral phase. We consider model quartzose and feldspathic sands. We generate moduli-porosity relationships for both the dry and water-saturated states. The ability to control pore space structure and mineralogy results in numerical data sets which exhibit much less noise than corresponding experimental data. The numerical data...[Show more]
