newssafely storing carbon dioxide
gorgon project uses CO2 technology to control emissions
The Gorgon liquefied natural gas project includes one of the largest carbon dioxide (CO2) capture and storage programs in the world. The CO2 present in the natural gas will be injected into a sandstone reservoir more than 1.5 miles (2.4 km) below Barrow Island.
More than 1.2 miles (2 km) beneath Barrow Island is the Dupuy Formation, a deep reservoir unit and the site of our Carbon Dioxide (CO2) Injection Project. For the Gorgon Project, part of the liquefied natural gas process involves separating CO2 from the natural gas stream to prevent its freezing into a solid. Standard industry practice calls for venting that excess CO2 into the atmosphere. But Chevron believes in protecting the environment, so we will inject the CO2 into the Dupuy Formation using nine injection wells directionally drilled from three drill centers.
An ongoing monitoring program, which includes observation wells and seismic surveys, will assist in managing the performance of the Dupuy Formation. Chevron is committed to executing projects in a safe and environmentally responsible fashion. With one of the largest CO2 capture and storage programs, that’s what we’re doing with Gorgon.
