Velocity-porosity relationships: Predictive velocity model for cemented sands composed of multiple mineral phases

Knackstedt, Mark; Arns, Christoph; Pinczewski, Wolf Val


Computer simulations are used to calculate the elastic properties of model cemented sandstones composed of two or more mineral phases. Two idealized models are considered - a grain-overlap clay/quartz mix and a pore-lining clay/quartz mix. Unlike experimental data, the numerical data exhibit little noise yet cover a wide range of quartz/cement ratios and porosities. The results of the computations are in good agreement with experimental data for clay-bearing consolidated sandstones. The ef...[Show more]
