Emissions advantage has become a key criterion in project sanction decisions. This has improved the relative attractiveness of the US GoM to upstream investors. We estimate the average intensity in the US GoM to be 7.4 tons of carbon dioxide equivalent per thousand barrels of oil equivalent (tCO2e/kboe) in 2023, while the global average for deep and ultra-deepwater fields is 14. Understanding the influences on emission intensity is a considerable challenge. Every part of the upstream system, from the reservoir properties to the export pipelines, affects how much carbon is emitted during production. We combine government data with Wood Mackenzie’s asset level emissions and subsurface data sets to explore the GoM’s emission advantage.
