As of September 30, 2023 and December 31, 2022, we had $10 million and $20 million, respectively, of exploratory well costs capitalized greater than one year related to suspended wells. Management believes these wells exhibit sufficient quantities of hydrocarbons to justify potential development. All of the suspended wells require completion activities in order to classify the reserves as proved. The decrease during the nine months ended September 30, 2023 included a reduction in suspended well costs as we recorded $10 million of dry well expense associated with drilled and uncompleted exploratory wells in Permian.
