Methodology changes that allowed for visibility of source of third-party water started in 2020. The 2021 total water withdrawal was reduced vs. 2020 due to rainfall at major sites and winter storm Uri, which had a broad impact on the U.S. Gulf Coast, resulting in unplanned shutdowns and production outages.
