These tables contain data relevant to Marathon Oil’s governance, environmental, safety, workforce and social performance. We understand that the accuracy of the data is inherently constrained by differing reporting rules, definitions, estimating methods and other factors. Marathon Oil endeavors to strengthen global data reporting systems and methodologies but recognizes as accuracy is improved, corrections will be needed periodically. In this table, some totals may not equal the sum of their components and separate calculations of other data may be affected due to independent rounding. The metrics above are for operations under direct Marathon Oil management and operational control. GHG emissions are estimated using industry guidelines (API’s Compendium of Greenhouse Gas Emissions Methodologies for the Oil and Gas Industry and the IPIECA/API/IOGP Petroleum Industry Guidelines for Reporting Greenhouse Gas Emissions). The gas capture percentage is the estimated volume of wellhead gas flared, over the estimated volume of gross gas produced. Except as noted, metrics in this table represent global performance.
ᵃ As of May 2022 Shareholder Meeting.
ᵇ Includes political action committee and corporate contributions.
ᶜ Greenhouse gas (GHG) carbon dioxide equivalent (CO₂e) emissions are based on carbon dioxide, methane and nitrous oxide from Marathon Oil-operated facilities only.
ᵈ See gross production. Applies to all intensity metrics based on total gross production.
ᵉ GHG emission values are inclusive of year-end acquisitions.
ᶠ Gas capture percentage: the percentage of volume of wellhead natural gas captured upstream of low pressure separation and/or storage equipment such as vapor recovery towers and tanks.
ᵍ Includes fresh and brackish water. Excludes recycled water volumes.
ʰ Defined as <1,000 ppm total dissolved solids (TDS) per U.S. Geological Survey.
ᶦ Data includes spills outside of secondary containment ≥ 1 barrel.
ʲ Non-oil includes some produced fluids, such as produced water, which may contain trace amounts of hydrocarbons and non-produced fluids such as drilling muds, fracturing and production chemicals. In 2019, two produced water spills of ~47,500 barrels accounted for total volume.
ᵏ Calculation is based on EPA grid data.
ˡ PSM covered facilities and Equatorial Guinea operations events only.
ᵐ Workforce statistics reflect year-end data.
ⁿ Workforce data has been updated to reflect full-time employees only and a calculation error in 2018 data.
ᵒ Data does not include total retirement rates of 2.0%, 1.7%, 1.4%, 1.3% and 1.4% for 2021, 2020, 2019, 2018 and 2017, respectively.
ᵖ Minority designation defined by Equal Employment Opportunity EEO-1 report categories.
