Hydrogeochemistry of Florida Karst Waters
The hydrogeochemistry of Florida’s limestone aquifers is complex, dominated by carbonate equilibrium reactions and the influence of seawater. Florida...

Energy storage in the geological subsurface: dimensioning, risk analysis and spatial planning: the ANGUS+ project
New techniques and methods for energy storage are required for the transition to a renewable power supply, termed “Energiewende” in Germany. Energy...

Sinkhole remedial alternative analysis on karst lands
Sinkholes are parts and characteristic features of typical karst systems. Extensive research has been done on investigation, monitoring, risk...

Hypogene Speleogenesis on the Florida Platform
The Florida Platform includes many examples of suspected hypogene karst, on- and offshore. These features occur in carbonate strata of Early...

Concept for an integral approach to explore the behavior of rock salt caverns under thermo-mechanical cyclic loading in energy storage systems
The fluctuating nature of renewable energy sources can be managed by storing the surplus of electrical energy in an appropriate reservoir. The excess...

Geo-mechanical Model Testing for Stability of Underground Gas Storage in Halite During the Operational Period
A 3D geo-mechanical model test is conducted to study the stability of underground gas storage in halite, modeled after the **tan gas storage...

Hypogenic Caves and Paleokarst of the Arbuckle Mountains, Oklahoma
The Arbuckle Mountains form a small but complex geologic province characterized by thick sequences of intensely folded and faulted carbonates,...

Utilization of a 3D webGIS to support spatial planning regarding underground energy storage in the context of the German energy system transition at the example of the federal state of Schleswig–Holstein
When decarbonizing a state-wide energy system by introducing a growing share of renewable energies, underground energy storage can help to deal with...

Physical Properties of Reservoir Rocks
A rock capable of producing oil, gas, or water is called reservoir rock. A reservoir rock may be any rock with sufficient porosity and permeability...

Hypogene Speleogenesis in the Southern Ozark Uplands, Mid-Continental United States
Giant spar crystals were discovered in Chilly Bowl Cave in northern Arkansas in an area of deep faults between the Ouachita orogenic province and the...

Mechanical Behavior of Salt Caverns: Closed-Form Solutions vs Numerical Computations
Creep closure and structural stability of a cylindrical elongated cavern leached out from a salt formation are discussed. The Norton-Hoff creep law,...

A Very Slow Creep Test on an Avery Island Salt Sample
The applied deviatoric stress during most creep tests performed on salt samples is in the 3.5–20 MPa range. However, the stresses actually...

Interpreting Evaporite Textures
I define an evaporite as a salt rock that was originally precipitated from a saturated surface or nearsurface brine in hydrologies driven by solar...
-
Micro-Macro Analysis and Phenomenological Modelling of Salt Viscous Damage and Application to Salt Caverns
This paper aims to gain fundamental understanding of the microscopic mechanisms that control the transition between secondary and tertiary creep...

Dispersive thermohaline convection near salt domes: a case at Napoleonville Dome, southeast Louisiana, USA
Density-driven flow around salt domes is strongly influenced by salt concentration and temperature gradients. In this study, a thermohaline...

Potash Resources: Occurrences and Controls
Natural potash evaporites are a typical part of a brine evaporation series, crystallizing at the higher concentration or bittern end, either at the...

Influences of filling abandoned salt caverns with alkali wastes on surface subsidence
Abandoned salt caverns, particularly those that allow free draining of brine, are serious potential causes of subsidence above salt mines. Filling...

Salt Dissolution and Pointers to Vanished Evaporites: Karst, Breccia, Nodules and Cement
Given enough time all subsurface evaporites eventually dissolve. Even in the subsurface sedimentary realm there are probably more intervals of...
