The characterization of fractures is essential to increase the production of hydrocarbon and geothermal resources. In this study, we investigate the effect of the fluid flow in the longitudinal fracture along a borehole on the dispersion and attenuat

The effect of tensile fracture in a vertical borehole under anisotropic horizontal stress conditions is numerically investigated in terms of the dispersion of flexural wave generated in dipole sonic logging. Our three‐dimensional model comprises a

Summary Fluid channels generated in the annulus of incompletely cemented cased holes are problematic in developing oil, gas, or geothermal resources. The dispersion curves of borehole modes in sonic logging bring additional information on the cement
