Abstract The standard Biot‐Gassmann theory of poroelasticity fails to explain strong compressional wave velocity dispersion experimentally observed in 12 tight siltstone with clay‐filled pores. In order analyze and understand the results, we developed a new double‐porosity model clay squirt flow where wave‐induced local fluid occurs between micropores aggregates intergranular macropores. is validated based on combined study ultrasonic experiments specimens at different saturation conditions...
2-D seismic modelling has notable dynamic information discrepancies with field data because of the implicit line-source assumption, whereas 3-D suffers from a huge computational burden. The 2.5-D approach is able to overcome both aforementioned limitations. In general, earth model treated as an elastic material, but real media viscous. this study, we develop accurate and efficient frequency-domain finite-element method (FEM) for viscoelastic wave propagation. To perform approach, assume that...
Abstract Compared with the seismic wave fields, influence of porosity and permeability to seismoelectric coupling may be more significant. The effect mainly forms coseismic signals (CS) interface response (IR). influences on two types field are still not clear. In this paper, we numerically analyze characteristics CS IR dependency permeability, respectively. differences in sensitivity fields also determined. results show that change is sensed by field, while has almost no obvious it: both...
For oil and gas seismic exploration, rock velocities are essential parameters to tease out reservoir properties from data. The ultrasonic pulse transmission (UPT) method has been a gold standard estimate in the laboratory. Regarding UPT method, accurate determination of travel time waves plays significant role robustly measuring velocities. One most conventional ways obtain is through arrival picking. However, unclear noise virtually exists preceding S-wave interfering with this picking,...
Summary A fully polarimetric borehole radar system with four combinations of dipole and cylindrical slot antennas was developed to acquire data sets in drilled boreholes. To better under the response subsurface fractures different roughness, this study, synthetic roughness are generated on a computer via fractal theory based simulation techniques. Quantitative assessment for is possible by use three main parameters: dimension, rms at reference length, length scale describing degree mismatch...
SUMMARY The monoclinic medium with a horizontal symmetry plane is gradually being studied for seismic anisotropy characterization. principle goal of this paper to investigate the effect fracture parameters (azimuth angle, density, aspect ratio, scale) on exact and approximate parameters. We derive porous media based Chapman model which accounts wave-induced fluid flow give expressions Thomsen-style (nine orthorhombic parameters: VP0, VS0, ϵ1, ϵ2, γ1, γ2, δ1, δ2, δ3, three ζ1, ζ2, ζ3...
Summary The Ordovician carbonates of the Yingshan formation in Tarim Basin present a complicated pore structure due to diagenetic and secondary structures. Seismic elastic properties (e.g., velocity) depends on porosity as well structure. We estimated average specific surface, pore-throat radius, roundness, aspect ratio carbonate rocks from Tazhong area. Measuring results show that high P-wave velocity samples have small large ratio. Diversity dense result fluid-related variability. For or...
3D modeling usually suffers from a huge computational burden, whereas 2D seismic generates noticeable dynamic information discrepancies with field data because of the implicit line-source assumption. The 2.5D approach is able to overcome both aforementioned limitations. In this study, we developed an accurate and efficient frequency-domain finite-element algorithm for viscoelastic media using irregular unstructured mesh. Two models, unbounded homogenous model rugged topography model, were...
