Journal ArticleDOI
Fluid mobility and frequency-dependent seismic velocity — Direct measurements
TL;DR: In this article, a forced deformation system is used in conjunction with pulse transmission to obtain elastic properties at seismic strain amplitude (10 −7 ) from 5 Hz to 800 kHz.
Journal ArticleDOI
Heavy oils—seismic properties
TL;DR: In this article, the simple empirical trends developed for light oils for fluid properties such as viscosities, densities, gas-oil ratios, and bubble points may not apply well to heavy oils.
Journal ArticleDOI
Impact of thermal maturation on nano-scale elastic properties of organic matter in shales
TL;DR: In this article, a non-destructive atomic force microscopy technique was used to map the elastic modulus of organic and inorganic components at the nanometer scale in shales containing Type II kerogen from three different levels of thermal maturation.
Journal ArticleDOI
Effect of image segmentation & voxel size on micro-CT computed effective transport & elastic properties
Nishank Saxena,Ronny Hofmann,Faruk O. Alpak,Jesse Dietderich,Sander Hunter,Ruarri J. Day-Stirrat +5 more
TL;DR: In this paper, the impact of the image segmentation threshold and image voxel size on image-computed porosity, elastic moduli, and electrical conductivity was studied.
Journal ArticleDOI
References and benchmarks for pore-scale flow simulated using micro-CT images of porous media and digital rocks

TL;DR: A novel reference dataset is generated to quantify the impact of numerical solvers, boundary conditions, and simulation platforms on permeability of microstructures ranging from idealized pipes to digital rocks and finds that more stringent convergence criteria can improve solver accuracy but at the expense of longer computation time.
