... strain rate signal occur earlier and last longer on the fiber optic waterfall plot, while larger SRV compressibility delays the signal. Strain values are negatively correlated with SRV Young's modulus. A larger simulated reservoir volume around fractures leads to wider tensional signals. This analysis...

A pulse-echo technique was used to measure the sonic velocity in CO2, methane, and their mixtures (containing 5 - 30 mol% CO2) in the pressure range of 1 – 200 bar and in temperaturerange of 300 – 323K. The corresponding density...
