a Based on data available for 2020. Note that only nearshore (but not inland) and offshore oil and gas operations were included. Inland operations are outside of the scope of the OITS IV.
b U.S. offshore data based on publicly available data from BSEE (available at www.data.bsee.gov).
c U.S. estimates calculated based on publicly available data from BSEE (available at www.data.bsee.gov). Eastern Canada estimates for produced water for gas production based on value for exclusive gas production in Nova Scotia coupled with produced water data from the same area (data from Canada-Newfound and Labrador Offshore Petroleum Board and Canada-Nova Scotia Offshore Petroleum Board). Estimates for Alaska based on State of Alaska data on well gas and oil production and associated produced water. Calculations conducted for gas production wells and oil production wells. Oil production wells generally also produce some gas.
d Alabama nearshore data available at https://www.gsa.state.al.us/ogb/production.
e Louisiana data from Louisiana Department of Natural Resources Office of Conservation (data for 2020). Texas data from Texas Railroad Commission (data for 2020) available at http://webapps.rrc.texas.gov/PDQ/generalReportAction.do.a
f Estimated based on 2.5 bbl water per bbl oil as per Veil (2011).
g Mexican production data from U.S. Energy Information Administration (available at https://www.eia.gov/international/analysis/country/MEX).
h Estimated based on 2.5 bbl water per bbl oil as per Veil (2011).
i California nearshore (state waters) data for Platforms Eva, Emmy, and Esther from California State Lands Commission. The WOR ratios are relatively high because the production rates are now relatively low, totaling less than 1.5 million bbl per year for all three platforms.
j Data from BSEE Pacific. The WOR ratios are relatively high because the production rates are now relatively low, totaling less than 4.4 million bbl per year for 11 leases.
k Data for Cook Inlet offshore production from State of Alaska (available at http://aogweb.state.ak.us/DataMiner3/Forms/Production.aspx).
l Totals for produced water without Mexico and Western GOM nearshore because no data are available.
m Totals including estimates for produced water for Mexico and Western GOM nearshore based on an estimate of 2.5 bbl water per bbl oil as per Veil (2011).
NOTE: SD = standard deviation.
