Q: How do we make sure that CO2 doesn’t leak from a sequestration site?

Cranfield Monitoring WellA: Careful Planning and Monitoring

When you go for a hike, you make sure that you've got good shoes and a hat, sunglasses and sunscreen. You get a map, plan where you are going, and check the weather conditions. You bring along water and a snack. Because you’ve planned for the trip you don’t expect any problems, but you still bring along a cell phone, both so you can check in with friends or family along the way and so you could let someone know in case of an emergency.

When carbon dioxide is injected underground, careful plans are made, and we are required to have monitoring and emergency systems in place too.


Susan Hovorka of the Gulf Coast Carbon Center approved this FAQ. She has developed monitoring strategies for carbon sequestration tests in Texas and Mississippi.



Dr. Katherine Romanak of the Gulf Coast Carbon Center approved this FAQ.  She has developed monitoring programs for numerous sequestration projects and has recently led an investigation into suspected CO2 leak from an injection site at the Kerr Farm in Saskatchewan, Canada.

The Department of Energy's National Energy Technology Laboratory sponsors a number of projects that harness various technologies, including chemistry, seismology, and satellite data, to improve monitoring at sequestration sites.
