Seismic waveforms contain much information that is ignored under standard processing
schemes; seismic waveform inversion seeks to use the full information content of the …

Different ground-penetrating radar (GPR) techniques have been tested on the same site in
order to establish the performance and reliability of this method when applied to civil …

The goal of this study is to understand and quantify the attenuation effects in the subsurface
and to create an accurate laterally and vertically varying quality factor Q model for gas …

We developed two methods of ray-based seismic attenuation tomography. One is amplitude
attenuation tomography, which uses amplitude attenuation of the first arrival P-wave. As …

The feasibility of carbon dioxide sequestration research at Cranfield, Mississippi is studied
by injecting millions tonnes of CO 2 into the lower Tuscaloosa sandstone Formation over a …

Ultrasonic measurements of acoustic wavefields scattered by single spheres placed in a
homogenous background medium (water) are presented. The dimensions of the spheres …

在时间域中, 利用地震记录中的振幅与上升时间信息可以计算出岩石介质的品质因子Q 值.
由于震源能量难以测量, 本文通过共炮点道集相邻道循环对比的方法, 消除了震源对计算过程的 …

Q model building, which is conventionally done in the data space using ray-based
tomography, is notoriously challenging due to issues such as spectral interference, low …
