GEOLOGIC STORAGE

WHAT IS GEOLOGIC STORAGE?

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.

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 store CO₂.

SAFE, SECURE CO₂ STORAGE

Once the compressed CO₂ is injected into the rock formation thousands of feet beneath the surface, it gets trapped through four natural 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 video below to see how these four trapping mechanisms work.

CARBON STORAGE MONITORING

These monitoring wells will be used to confirm that the CO₂ remains safely trapped in the storage reservoir deep below the surface.

WELL DEPTH

Injection wells are used to transport the CO₂ more than 5,000 feet below the surface where it will be securely stored below a layer of impermeable rock (a primary seal or caprock) that is greater than 100-feet-thick. The CO₂ will become trapped within the rock formation.

The CO₂ storage operations will not affect the Parish’s water resources. The deepest water well is approximately 2,300 feet below the surface, and the deepest zone designated as Underground Source of Drinking Water (USDW) is approximately 3,000 feet. The CO₂ will be stored more than a half mile below that zone.

SAFETY AND SECURITY

Geologic storage 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 and secure 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 storage
These MRVs programs include protocols for calculating and monitoring sequestered CO₂
Surface equipment will be designed with redundancy and failsafe programs with remote monitoring and intervention technologies to maximize site safety and mitigate risk
