Among subsurface hydrogen storage methods, caverns formed by solution mining in salt formations have proven effective due to salt’s self-healing behavior and lack of chemical reactivity. The Delaware Basin, with its extensive bedded salt formations, offers opportunities for hydrogen storage. This case study used well data with Gamma Ray, Density, and Sonic log curves to identify and characterize the Castile and Salado Formations. Gamma Ray curves helped identify formation boundaries, and Density and Sonic logs differentiated halite- and anhydrite-rich members within the two formations. Halite-to-bulk salt thickness ratios were calculated to pinpoint significant halite accumulations. The study identified thicker salt deposits in specific regions, particularly in Lea County, Southern New Mexico, and Loving and Winkler Counties in Texas. The Castile Formation showed more predictability when using well-logs in the identification of cycles of halite and anhydrite, while the Salado Formation’s posed predictability challenges when trying to halite heterogeneity. The research provides insights and a petrophysical workflow applicable to other salt-bearing basins for assessing hydrogen storage potential.
