Companies Coterra Energy Inc FollowNov 4 (Reuters) - Shares of shale oil and gas producer Coterra Energy fell as much as 8% on Friday after the company cut its estimate of proven oil reserves, a key measure of future production growth.
Coterra, which formed a year ago through the merger of Cimarex Energy and Cabot Oil & Gas, said proved reserves on its books will drop roughly 15% to 20% year-over-year at December 31, 2022.
The decline was driven by a roughly 32% to 36% decline to gas reserves in its Marcellus shale properties in the Eastern United States that came with the Cabot acquisition.
Rival U.S. shale oil producer EOG Resources said oilfield costs could increase by 10% next year, on top of a 7% increase in 2022, as inflation continues to snarl the energy industry.
EOG, which this week announced it had extended operations into Ohio, said it will maintain low single-digit oil production growth next year.
