It is not a major concern for upstream oil and gas production, except possibly in the case of gas processing plants located far from extraction sites, since oil and gas fields are usually associated with the type of sedimentary formations needed. However, where needed for other industries, the new method developed in Iceland to incorporate injected C02 into basaltic rocks shows great promise, and is thought to be even cheaper than more traditional options.
