As the world moves toward 'net zero' carbon emissions, this course explains reservoir-based geo-energy, and how old concepts (petroleum), are adapted to new, greener solutions (white/gold/geologic hydrogen, and enhanced geothermal systems). Lectures discuss genesis and migration of the fluids involved; reservoir properties and evolution; how the resources are drilled; environmental impacts (carbon cycle and climate change; ground water, surface and atmospheric pollution); and mitigations (well-site design and safety; carbon capture and storage/conversion). Labs focus on aspects of resource evaluation using drill-hole and geophysical data.
