Energy Efficiency

We continually strive to make our operations more energy efficient. This can provide environmental and economic benefits through lower production costs or greater sales revenue. Through the natural decline of production, as our fields diminish in size, they tend to require either the same, or in some cases, even greater amounts of energy to extract the product for processing or refining.   

Total energy consumption in 2022 was 206 trillion British Thermal Units (BTUs). Approximately 97% of our consumption was combustion of fuel for our own energy use with the remainder from purchased electricity. 

Water

Water sourcing and produced water management are global challenges that require local solutions. We manage water risks and mitigate potential impacts to water resources, taking into account the unique hydrologic, quality, use and ecological settings of each basin or offshore marine area. Water-related risks associated with fresh water withdrawal, water stress, offshore produced water discharges and onshore produced water disposal can affect our business. Read more about how we manage our water risks.

We measure and report on the volume of fresh water and non-fresh water withdrawn from local water sources, the volume of municipal waste water reused, and the volume of produced water that is reused, recycled, disposed or discharged after treatment. The data are used to estimate our water intensity and exposure to water stress. We also collect water forecast data for our Long-Range Plan which enables us to test our portfolio of projects against our water risks to make better-informed strategic decisions. 

The 2022 fresh water consumption intensity for our unconventional assets in the U.S. (Eagle Ford, Delaware, Midland and Bakken) and in Canada (Montney) was 0.06 bbl/BOE EUR. The 2022 fresh water consumption intensity for our conventional (Alaska, Canada Surmont, LNG and Indonesia) and offshore assets (Norway) was 0.03 bbl/BOE. Read more about our water metrics.

We use the World Resources Institute Aqueduct Risk Atlas to assess our portfolio exposure to water stress. Our Anadarko, Permian Midland Basin and Alaska Kuparuk assets are located in basins with high or extremely high baseline water stress and accounted for 6.3% of our total fresh water withdrawal and 2.4% of our total fresh water consumption in 2022. However, we have divested many of our assets with high water stress; the Lost Cabin Gas Plant and the majority of our Anadarko and Permian conventional assets were divested in 2021 and 2022.
