Chevron has started drilling carbon dioxide injection wells as part of its liquefied natural gas (LNG) project in Western Australia, Oil & Gas Journal reports. The wells are expected to reduce the project’s greenhouse gas emissions by about 40 percent, the publication says.
The CO2 injection project on Barrow Island, part of Chevron’s Gorgon-Jansz LNG project, involves the design, construction and operation of facilities to inject and store CO2 extracted from the natural gas feed into the LNG plant, the magazine says.
Chevron says it expects to inject 3.4 to 4 million metric tons of CO2 into the storage reservoir each year and says there is likely to be a total of 100 million metric tons injected during the 40-year life of the project.
North America is the global leader in developing and deploying carbon capture and storage (CCS) and carbon capture utilization and storage (CCUS), with seven of the world’s 12 operational large-scale integrated projects located in the US and one in Canada, according to a study by the Global CCS Institute published in October.
These 12 projects prevent the release of 25 million metric tons a year of greenhouse gases. An additional eight projects under construction will increase the total to 38 million metric tons a year by 2016, the report says.
