Offshore Energy Security Act of 2023

This bill requires the Secretary of the Interior to hold at least four offshore oil and gas lease sales in the Gulf of Mexico within two years of enactment (by August 2025), each offering a minimum of 74 million acres. It mandates that these sales follow specific terms from prior lease sales (Gulf of Mexico Sale 257) and waives delays under existing law. The bill also prevents environmental lawsuits from halting lease issuance or delaying drilling permits, requiring courts to remand environmental issues to the Secretary instead of vacating leases. This directly affects oil and gas companies bidding on leases and federal agencies managing offshore leasing.
