Chapter
Closing Remarks
This book gave an introduction into the thermo-mechanical modelling of rock salt in general, and of gas storage in salt caverns in particular. There are many topics that were not discussed here but that are ve...

Chapter
Introduction
The rising energy demand of the growing world population is a significant cause for environmental risks associated with harmful emissions, hazardous waste, destructive land use, etc. This creates a pressing ne...

Chapter
Simulating Gas Storage in Salt Caverns
Salt caverns are artificial cavities in salt formations, which are usually used for long-term storage of hydrocarbons such as black oil or natural gas. At least two facilities, located in MacIntosh, USA (Power...

Chapter
Simulation of Laboratory Tests
The input files of all subsequent examples can be found on the OGS website https://docs.opengeosys.org/books. In the sequel, we will describe selected input files and keywords relevant to the specific examples. M...

Chapter
Basics of Thermomechanics and Inelasticity
Rock salt can undergo large inelastic deformations over extended periods of time. Many analyses, however, refer to time intervals and mechanical loads that cause deformations for which the small-strain assumpt...

Chapter
Geothermal Energy
Welcome to the OGS HIGRADE Tutorials on Computational Energy Systems. The first tutorial will introduce the reader to the field of modeling geothermal energy systems. In the beginning chapter we will introduce...

Chapter
Numerical Methods
There are many alternative methods to solve initial-boundary-value problems arising from flow and transport processes in subsurface systems. In general these methods can be classified into analytical and numer...

Chapter
Introduction to Geothermal Case Studies
This section is an appetizer to continue working with the OGS tutorials—after a rather theoretical introduction. We show some of the OGS applications in advanced geothermal reservoir modeling. You also may loo...

Chapter
Theory
In this chapter we briefly glance at basic concepts of porous medium theory (Sect. 2.1.1) and thermal processes of multiphase media (Sect. 2.1.2). We will study the mathematical description of thermal processe...

Chapter
Deformation Processes
This section presents a set of closed form solutions of 3D problems on shear and torsion. The associated simulation exercises have been checked by OGS; they may serve as verification tests.

Chapter
Heat Transport Exercises
After the theory lectures touching aspects of continuum mechanics of porous media, thermodynamics and an introduction of numerical methods, now we conduct five exercises on heat transport simulation using OGS—...

Chapter
Mechanical Processes
This section introduces benchmarks to verify the implementation of a pressure boundary condition for mechanical processes.

Chapter
Evaluation of Geo-processes
A holistic understanding of the physicochemical processes induced by CO2 injection and storage in a reservoir is based on a geoscientific characterisation of the overall geological system consisting of reservoir ...

Chapter
Heat Transport
In the first benchmark chapter we consider heat transport in a porous medium described by the heat balance equation (2.78).

Chapter
Theory
Concerning the theoretical background of flow, transport, deformation, and reaction processes in porous media, there is a considerable amount of monographic literature available [8, 9, 10, 11, 12, 13, 14, 15]....
