Ultrasonic Shear Wave Velocity and Attenuation during methane hydrate formation in water saturated sandstone (NERC Grant NE/J020753/1)

This dataset is of laboratory ultrasonic shear wave measurements during methane hydrate formation in water saturated Berea sandstone using pulse echo method. We formed methane hydrate and took shear wave measurements during the formation process at different time interval. The hydrate saturation was calculated from measured pressure and temperature changes. This data set was used to show how shear wave velocity and attenuation can be used to estimate permeability of hydrate-bearing geological formations. We observed that velocity and attenuation both increase with hydrate saturation, with two peaks in attenuation at hydrate saturations of around 6% and 20% that correspond to changes in gradient of velocity. These laboratory experiments were conducted in National Oceanography Centre, Southampton by Sourav Sahoo with technical support provided by Laboratory Manager Laurence North. Sourav Sahoo interpreted the data. The hydrate formation process continued for few days and measurements were done mostly during daytime due to limited laboratory access during the night. This data set has been used for the paper published in Journal of Geophysical Research: Solid Earth (DOI 10.1029/2021JB022206)

Statement

We formed methane hydrate in a cylindrical sample of Berea sandstone (4.97 cm diameter, 2.06 cm height; 22% porosity, 448 mD permeability) inside a stainless-steel pressure cell. We used the pulse-echo system and signal analysis described in detail in Sahoo et al., (2019), after Winkler and Plona (1982). The method is described in details in published paper. This dataset includes shear wave measurements done during methane hydrate formation in Berea Sandstone. We formed methane hydrate and took shear wave measurements during the formation process at different time interval. The experimental setup is described in the main manuscript. Several files are included in the data set. Each files is one measurement during hydrate formation. So each file has a different hydrate saturation.
