Evaluation of carbonate pore system under texture control for prediction of microporosity aspect ratio and shear wave velocity
TL;DR: In this paper, a suite of carbonate rocks from Albian age in the Campos Basin in Brazil, complemented by data from the literature, totaling 472 samples with detailed description of diagenetic features, quantitative mineralogy analyses, and P- and S-wave velocities (Vp and Vs) measured at three ranges of effective pressure loading: low (5-7.5), moderate (20), and high (40-50) values.

Dynamic characterization of shale systems by dispersion and attenuation of P- and S-waves considering their mineral composition and rock maturity
TL;DR: In this article, the dynamical elastic effective properties of gas-oil shale systems are found by using the self-consistent method and from them, dispersion and attenuation of P- and S-waves are calculated for a wide range of frequencies including seismic, sonic and ultrasonic bands.
Journal ArticleDOI
Changes in crack aspect-ratio concentration from heat treatment: A comparison between velocity inversion and experimental data
TL;DR: In this article, a modified Cheng-Toksoz velocity inversion model using a differential effective medium was used to investigate the physical significance of the inversion. But the authors did not consider the effect of heat-cycling on the pore-crack aspect-ratio spectrum.

Investigation on the mechanical properties and mechanical stabilities of pipewall hydrate deposition by modelling and numerical simulation
TL;DR: In this paper, a structural model for pipewall hydrate deposition is established based on particle packing theory using this structural model, the main mechanical parameters of pipe hydrate deformation, internal stress distribution and failure of pipeline hydrate filling when it is under the action of external forces are investigated and the influences of flow rate, deposition thickness and deposition length are investigated.
Journal ArticleDOI
Accuracy of the replacement relations for materials with non-ellipsoidal inhomogeneities
TL;DR: In this article, the replacement relation that links the property contribution tensors of inhomogeneities having the same shape but different elastic properties has been studied for nonspherical shape.
