Energy Excursions

# Class VI Wells

"Take an energy excursion to explore the collaborative contributions of the scientific community to establishing wells specifically for the injection of carbon dioxide, as well as the safeguards in place for protecting groundwater, health and safety."

## Summary

This lesson explores the international application of carbon-dioxide injection technology specifically for carbon storage, and the contributions from the United State government and the Texas Bureau of Economic Geology. Motivation for this lesson is the importance of scientists and engineers to repurpose and expand existing technology for new applications, and the important regulatory rules developed for new applications to ensure protection of the environment, health and safety. “Class VI Wells” lays the foundation for understanding greenhouse gas reduction projects designed to incorporate not only utilization of carbon dioxide, but the permanent storage of carbon dioxide in the subsurface in a Class VI well.

## Learning Outcomes
