The Offshore Energy Security Act of 2025 aims to increase offshore oil and gas production by requiring the Secretary of the Interior to conduct a series of lease sales in the Gulf of Mexico. The primary objective is to enhance energy security by making more offshore resources available for exploration and extraction. Key provisions of the Act include a mandate for the Secretary to hold at least 20 offshore lease sales over a ten-year period, starting from the date the law is enacted. These sales must adhere to specific terms and conditions outlined in a previous lease sale notice.
