In this SEG eight-hour course the basic physics and associated modeled petrophysics relevant to Hydrogen are presented, including the descriptions of the gas, liquid, and super critical phases (scCO₂).
Who Should Attend:
The course is designed to be followed by anyone with a broad geoscience background: no specific detailed fore-knowledge is required, although a familiarity with geophysical, exploration and drilling terminology will be useful.
Objectives
- Understand the physics relevant to Hydrogen and its phases. Understand what supercritical Hydrogen is and why it is relevant to subsurface storage and monitoring. Understand basic injector geometries potentially used in underground gas storage.
- Identify the physics and petrophysics relevant to Hydrogen detection in all reviewed geophysical methods. Understand the ambiguities and potential pitfalls of the various geophysical methods applied to Hydrogen monitoring
- Review the importance of a thorough understanding of fracture, fracture geometries and the importance of these data to injection and storage characteristics.
- Recognize the methods previously used, and know from direct review of geophysical interpretations, for Hydrogen subsurface imaging and monitoring.
- Estimate the most useful geophysical techniques relevant to a variety of potential scenarios at hypothetical Hydrogen monitoring at storage sites.
Course Content
In this SEG eight-hour course the basic physics and associated modeled petrophysics relevant to Hydrogen are presented, including the descriptions of the gas, liquid, and super critical phases (scCO₂).
In this course topics relevant to the storage and utilization of Hydrogen to enhance global energy security and sustainability are presented. Hydrogen is an especially appealing for energy utilization because of a high energy density of the resource and the lack of CO2 emissions from combustion. In this SEG one-day course the basic physics and petrophysics relevant to Hydrogen are presented, including the descriptions of the Hydrogen gas, liquid and super critical phases (scH2). The hydrogen supercritical phase is a material state in which there is no surface tension, somewhat like a gaseous state. After this review, and review of geophysical methods relevant to Helium monitoring and subsurface accounting, Helium (He) reservoir and case studies are reviewed with respect to monitoring technologies that could be applied to Hydrogen subsurface monitoring. Successful methods of geophysical monitoring of other injection sites, where relevant, will also be reviewed and summarized.
This SEG one-day course is then extended to a description of the physical properties of Hydrogen stability ranges, and moduli. These are then related to geophysical methods that have been used successfully to monitor, verify, and account for subsurface Hydrogen in geophysical studies. Successful geophysical monitoring technologies reviewed include microgravity, electromagnetic, satellite-based surface deformation monitoring, 3D and 4D reflection seismic based methods, vertical seismic profiling (VSP) and micro seismic. At the conclusion of the SEG one-day course the participant should have an solid understanding and introduction to the material properties of Hydrogen, petrophysical changes expected from the presence of Hydrogen as a pore filling phase in the subsurface, the possible scale of the Hydrogen energy component to our energy economy, and a thorough review of geophysical methods that have been successfully applied to monitoring subsurface Hydrogen.
