“…AS1, AS4, and AS5 are shallow water central hub facilities likely involved in processing and transmission of oil and gas. Throughput at these facilities may include transmission of deep water production to shore , (SI Appendix S8). Each facility is composed of a complex of platforms (between 7 and 16 platforms per facility).…”

“…This study presents airborne measurements of offshore platforms in the U.S. Gulf of Mexico. The Gulf of Mexico outer continental shelf comprises 18% of U.S. oil production and 3% of U.S. natural gas production for 2017. , Platforms in the Gulf of Mexico are typically categorized as shallow water if the local bathymetry is shallower than ∼200 m , and deep water when located at greater depths. The shallow water Gulf of Mexico is primarily a historically developed natural gas basin with most of its proved reserves already produced and thus characterized by rapidly falling counts of active oil and gas platforms .…”

“…The shallow water Gulf of Mexico is primarily a historically developed natural gas basin with most of its proved reserves already produced and thus characterized by rapidly falling counts of active oil and gas platforms . The deep water Gulf of Mexico is a recently tapped oil basin experiencing rising oil production as technological advancements have allowed for deeper and more extensive projects. , Generally, activities in deeper water require greater consolidation of operations relative to shallow water. While the infrastructure differs between offshore and onshore basins, oil and gas activities are similar.…”

Methane (CH 4 ) emissions from oil and gas activities are large and poorly quantified, with onshore studies showing systematic inventory underestimates. We present aircraft measurements of CH 4 emissions from offshore oil and gas platforms collected over the U.S. Gulf of Mexico in January 2018. Flights sampled individual facilities as well as regions of 5−70 facilities. We combine facility-level samples, production data, and inventory estimates to generate an aerial measurement-based inventory of CH 4 emissions for the U.S. Gulf of Mexico. We compare our inventory and the Environmental Protection Agency Greenhouse Gas Inventory (GHGI) with regional airborne estimates. The new inventory and regional airborne estimates are consistent with the GHGI in deep water but appear higher for shallow water. For the full U.S. Gulf of Mexico our inventory estimates total emissions of 0.53 Tg CH 4 /yr [0.40−0.71 Tg CH 4 /yr, 95% CI] and corresponds to a loss rate of 2.9% [2.2−3.8%] of natural gas production. Our estimate is a factor of 2 higher than the GHGI updated with 2018 platform counts. We attribute this disagreement to incomplete platform counts and emission factors that both underestimate emissions for shallow water platforms and do not account for disproportionately high emissions from large shallow water facilities.

“…Another class is model addition experiments, which are run to calibrate extra model components introduced to account for previously unaccounted phenomena; e.g., with applications in troubleshooting, retrofitting, or decommissioning. [29][30][31] These additional data, taken directly from the full-scale processing plant, are required to capture atypical process behaviour before drawing any conclusions.…”
