Energy Excursions

# Macondo Well Case Study

“Now that we have gained a better understanding of the critical steps and processes needed to ensure subsurface containment for oil and gas wells, let’s take an excursion to the offshore Gulf of Mexico to examine a case where several of these protocols were not followed and devastating consequences ensued.”

## Summary

This lesson takes a deep dive into the Deepwater Horizon disaster and the Macondo well blowout, a disastrous loss of containment in the subsurface, resulting in a rig explosion, a large oil spill in the Gulf of Mexico, and a tragic loss of life. Motivation for this lesson is to understand how in April of 2010 the integrity of the well was compromised due to a number of failures. As a result of the blowout, a number of safety and regulatory changes were instituted to prevent similar disasters in the future. This lesson is a capstone lesson for this course, pulling together vocabulary, concepts, and understandings from previous lessons and applying them to this case study of the Macondo Well blowout. The learner is asked to critically evaluate some of the failures in light of their newfound knowledge.
