EPA has stated that emissions of carbon dioxide, methane, and other greenhouse gases (GHGs) present an endangerment to public health and the environment because emissions of such gases are contributing to the warming of the earth’s atmosphere and other climate changes. Whiting not only complies with the requirement to track and report GHG emissions, but we also work to reduce emissions of GHGs. For more information on how we reduce emissions, see Gas Gathering and Processing, Reduced Emissions Completions, Leak Detection and Repair (LDAR) Program, Facility Environmental Inspections and Maintenance.
To track and report GHG emissions, Whiting estimates emissions in accordance with the requirements of EPA’s Mandatory Greenhouse Gas Reporting rule (40 CFR Part 98). These emissions are reported to EPA annually for each calendar year and reports are made publicly available on EPA’s webpage at www.epa.gov/ghgreporting.
At Whiting, we measure or estimate emissions of methane, carbon dioxide and nitrous oxide for multiple emission source types throughout the production, gathering, and processing segments. We measure GHG emission rates for sources that use actual measured data in GHG emission calculations, such as reciprocating rod packing vents and gas plant equipment leaks. We estimate and report other GHG emission sources, such as equipment leak emissions, in accordance with EPA’s emission calculation methodology.
Low-Emitting Pneumatic Controllers
Whiting has implemented a policy to require that any equipment either purchased, replaced or modified must be fitted with a low-bleed natural gas, no-bleed natural gas, compressed air, or equivalent pneumatic controller and to encourage the replacement of existing high-bleed natural gas pneumatic controllers, except where safety or operational conditions require a higher-emitting controller. Whiting believes such a policy greatly reduces its carbon footprint, pollutant,and greenhouse gas emissions and conserves valuable natural resources. At this time, Whiting believes it has eliminated high-bleed pneumatic controllers from it’s operations. Additionally, Whiting looks for opportunities to eliminate or control emissions from the remaining low-bleed pneumatic controllers by
- Routing their emissions back into the process,
- Routing their emissions to a combustion device,
- Using electrically actuated controllers, or
- Using compressed air as the pneumatic source.
In 2018, Whiting Petroleum planted over 7,000 trees in Mountrail County North Dakota to offset our carbon footprint in our operating area. Trees and forests are an important resource, providing watershed protection, wildlife habitat, recreational opportunities and protection for crops, soil and livestock. Currently about 1.8 percent of North Dakota’s total land area is forested but about 70 percent of North Dakota’s forest land is privately owned. This project brought Whiting, wildlife groups and private landowners together to create large-scale tree and shrub plantings on private land that will serve as habitat for future generations.
