GEOLOGIC SEQUESTRATION

WHAT IS GEOLOGIC SEQUESTRATION?

Geologic sequestration is a proven method of underground carbon dioxide (CO₂) storage. CO₂ is injected into deep rock formations for long-term storage. By capturing CO₂ and storing it in rock thousands of feet below the earth's surface, 1PointFive can reduce CO₂ in the atmosphere—protecting the climate, the planet, and future generations.
 
Geologic sequestration has been in use for decades. The history of intense study and real-world application by leading experts in geology, seismology, fluid characterization, well engineering, and reservoir modeling means that today, we have a proven tool to capture and store CO₂.

SAFE, SECURE CO₂ STORAGE

Once the compressed CO2 is injected into the rock formation thousands of feet beneath the surface of the earth, it stays safe and securely through one of four natural trapping mechanisms:​

STRUCTURAL TRAPPING
Impermeable caprock isolates the CO₂

DISSOLUTION TRAPPING
CO₂ dissolves into naturally occurring salt brines

RESIDUAL TRAPPING
CO₂ is immobilized and contained in tiny pores

MINERAL TRAPPING
CO₂ becomes part of the rock

Watch the sequestration video below to see how these trapping mechanisms work.

TYPICAL SEQUESTRATION WELL DEPTH

Sequestration sites will have multiple monitoring wells for every CO₂ injection well to confirm CO₂ is safely trapped in the storage reservoir deep below the surface.

SAFETY AND SECURITY

Geologic sequestration is a method of securing CO₂ in deep geologic formations. 1PointFive uses multiple layers of steel or chrome casing and cement to ensure the safe and secure storage of that CO₂. These are known as Underground Injection Control (UIC) Class VI wells. These wells are engineered to protect underground drinking water sources and ensure safe, long-term storage. The United States Environmental Protection Agency (EPA) controls and oversees the permitting of operations and Class VI wells in Texas.

 

The EPA developed specific criteria for Class VI wells (Learn more about Class VI wells | US EPA):

​

  • Construction and operation requirements

  • Comprehensive monitoring for safe injection and storage

  • Protection of groundwater quality 

  • Robust financial responsibility assuring the availability of funds to monitor and close the project out

  • Reporting and recordkeeping

MONITORING, REPORTING, AND VERIFICATION (MRV)

Our highest priority is to conduct our business in a manner that protects the health, safety, and welfare of communities, our employees, and the environment. 1PointFive geologic storage projects will be equipped with comprehensive measures to store CO₂ in a safe, secure, and permanent manner. Our operations are supported further by our parent company, Oxy, and their 50-year record of carbon leadership and innovative carbon storage programs.

​

  • Oxy developed the first two U.S. EPA-approved MRV programs for CO₂ sequestration

  • These MRVs include protocols for calculating and monitoring sequestered CO₂

  • Surface equipment is designed with redundancy and failsafe programs with remote monitoring and intervention technologies to maximize site safety and mitigate risk
