... ABSTRACT Elastic properties of rocks control the behavior of seismic waves such as wave amplitudes and speeds. Usually, elastic properties of rocks are measured in the laboratory. Unfortunately, some laboratory measurements are invasive. Digital Rock Physics (DRP) provides an alternative...

..., then compared to laboratory measurements. At a first order, the rocks scanned at multiple resolutions show no obvious effect on property estimation compared to laboratory measurements. The low resolution scans were computationally efficient, and accuracy was not compromised. This abstract provides further...

... ABSTRACT We have conducted the laboratory measurements of elastic parameters of dry and partially water-saturated sandstones at frequency range from 2Hz to 500 Hz. Two sandstone samples with similar porosity of 20% but different permeability of 33 mD and 1830 mD. The measured results indicate...

... that the frequencydependent attenuation can be attributed to mesoscopic wave-induced fluid flow (WIFF) caused by heterogeneities in water saturation. Introduction Laboratory measurements of attenuation in the seismic frequency range (<100 Hz) are not widely available for fluid-saturated rocks (Subramaniyan et al...

... at a specific condition, special laboratory measurements on oil and sands of heavy oil sands rock are designed and performed for three artificial samples. By the improved laboratory approaches, we can gain an insight into the physical interaction between the solid and fluid components in heavy oil sands...

... Summary We have continuously made progress in dispersion/attenuation study in laboratory measurement. We calibrated the lab low frequency measurement system for velocity dispersion and wave attenuation. And we test the system by measuring some dry samples, which shows our system can produce...

... Summary Laboratory measurements of seismic attenuation were performed on borosilicate samples using the forced oscillation method. First, we studied the effect of partial water-air saturation. Significant and frequency-dependent attenuation was only observed at nearly full water saturation...

For example, permeability can be successfully predicted by numerically simulating fluid flow through 3D rock models, with the numerical results being in reasonable agreement with laboratory measurements...
