Will salt repositories be dry
TLDR
The idea that salt was uniformly "dry" was revised when exploratory drilling in the vicinity of the Waste Isolation Pilot Plant (WIPP) in New Mexico encountered brines within the Castile Formation, an evaporite deposit below the Salado Formation as mentioned in this paper.Abstract:
The National Academy of Science committee that considered geologic disposal of nuclear waste in the mid-1950s recommended salt as a repository medium, partly because of its high thermal conductivity and because it was believed to be “dry” (perhaps the appropriate thought is “impermeable”). Certainly, the fact that Paleozoic salt deposits exist in many parts of t h e world is evidence for very low rates of dissolution by moving groundwater. The fact that the dissolution rates were so small led many scientists to the conclusion that the salt beds were nearly impermeable. The major source of brine within the salt beds was thought to be fluid inclusions within salt crystals, which could migrate through differential solution toward a source of high heat. The idea that salt was uniformly “dry” was revised when exploratory drilling in the vicinity of the Waste Isolation Pilot Plant (WIPP) in New Mexico encountered brines within the Castile Formation, an evaporite deposit below the Salado Formation. The brine reservoirs were thought to be isolated pockets of brine in an otherwise “impermeable” salt section.read more

Review of CO2 storage efficiency in deep saline aquifers
TL;DR: The concept of CO 2 storage efficiency is defined as the ratio of the volume of the CO 2 injected into an aquifer rock volume to the pore space in that volume.

Salt Tectonics: Principles and Practice
TL;DR: The salt tectonics is the study of how and why salt structures evolve and the three-dimensional forms that result as discussed by the authors, and it is also vitally important to the petroleum industry.

Dolomitization: from conceptual to numerical models
TL;DR: In this paper, the authors provide a quantitative framework for conceptual models of dolomitization, using analytical and, particularly, numerical simulation models of fluid flow and rock-water interaction.

Fluids and pressure distributions in the foreland-basin succession in the west-central part of the Alberta basin, Canada: Evidence for permeability barriers and hydrocarbon generation and migration
Karsten Michael,Stefan Bachu +1 more
TL;DR: In this paper, the authors studied the effect of tectonic relaxation, uplift, and erosion on the Laramide orogeny in the Alberta basin and found that overpressures are still maintained in strata of the Cretaceous Mannville and Colorado groups in areas adjacent to the deformation front.

Darcy's law in saturated kaolinite
TL;DR: In this paper, the authors used a multispeed syringe pump and a differential pressure transducer to measure the hydraulic conductivity of saturated natural clays and clayey sediments.
WIPP horizon in situ permeability measurements. Final report
TL;DR: In this paper, the results of twelve Phase I tests were used to determine: the permeability and porosity of the competent salt, the variability of the measured porosity with distance from the mined surface, and the influence of the interspersed clay and anhydrite seams on the measured permeability values.
