Elastic properties of salt: laboratory measurements, well-log analysis, and a seismic survey over the Hockley Salt Mine, Texas
Salt plays a significant part in the geology of the Gulf of Mexico area (GoM). Numerous basins in the world have undergone evaporation sequences that have deposited vast quantities of salt. Sometimes these deposits have remained largely undeformed, which can lead to anisotropic crystal growth, …
