Proved Oil and Gas and Other Asset Impairments

Due to the reduced demand from the COVID-19 pandemic causing an unprecedented downturn in the price of oil and reductions in near-term capital investment, Devon recognized approximately $2.7 billion of proved asset impairments during the first quarter of 2020. These impairments related to the Anadarko Basin and Rockies fields in which the cost basis included acquisitions completed in 2016 and 2015, respectively, when commodity prices were much higher. During the first quarter of 2020, Devon also recognized $2 million of product line fill impairments.

Unproved Impairments

Due to the downturn in the commodity price environment and reduced near-term investment as discussed above, Devon also recognized $110 million of unproved impairments during the first three months of 2020, primarily in the Rockies field.
