Effect of CO2 on coal P-wave velocity under triaxial stress
International Journal of Mining Science and Technology, 2022 As P-wave velocity is sensitive to the variations in coal reservoir parameters, it is possible to monitor the injected CO2 through P-wave velocity during CO2 sequestration in coal.

Prediction of seismic P-wave velocity using machine learning [PDF]
Solid Earth, 2019 Measurements of seismic velocity as a function of depth are generally restricted to borehole locations and are therefore sparse in the world's oceans. Consequently, in the absence of measurements or suitable seismic data, studies requiring knowledge of ...

Study on P-wave and S-wave velocity in dry and wet sandstones of Tushka region, Egypt
Egyptian Journal of Petroleum, 2015 Acoustic laboratory measurements have been conducted for forty-two sandstone samples at fully air and water saturation. This study is an attempt to learn more about the behavior of both P-wave and S-wave velocity in porous sandstone rock samples for both

A method to model the effect of pre-existing cracks on P-wave velocity in rocks
Journal of Rock Mechanics and Geotechnical Engineering, 2020 Crack closure is one of the reasons inducing changes of P-wave velocity of rocks under compression. In this context, a method is proposed to investigate the relationships among P-wave velocity, pre-existing cracks, and confining pressure based on the ...

Inversion of P-wave velocity anisotropy [PDF]
Geophysical Journal International, 1977 Summary. We examine the way in which measurements of velocity anisotropy can add to our understanding of upper mantle structure. Measurements of P-wave velocity anisotropy in a single plane contain very little direct information about the anisotropic structure. A promising technique is to fit the observed velocity variation with a mixture of an assumed
