The US Bureau of Ocean Energy Management (BOEM) has announced a new oil and gas lease sale scheduled for 11 March in the US Gulf of Mexico.

Scope and Scale of the Auction

The upcoming March sale will offer approximately 80 million acres for lease, which constitutes roughly half of the total 160 million acres within the US Gulf’s Outer Continental Shelf. This offering spans nearly 15,000 unleased blocks in the basin, mirroring the scale of a similar auction scheduled for 10 December.

Royalty Rate and Legal Framework

The leases will be offered at a 12.5% royalty rate. This is the minimum rate permitted by the One Big Beautiful Bill Act (OBBBA). This legislation mandates that BOEM conduct 30 lease sales, equating to two per year, through the year 2040.

BOEM's Emphasis on Predictability

In its announcement, BOEM highlighted the establishment of a "predictable sale schedule" for Gulf auctions. The agency contrasted this current predictability with the administration of the previous president, which held only three Gulf lease sales over a four-year period. A BOEM official stated that by offering leases at the competitive 12.5% royalty rate, the sale signals the end of an "era of regulatory uncertainty" and the beginning of a new phase of "responsible energy leadership."

Legal Challenge

Concurrent with this announcement, environmental groups have initiated legal action by filing a lawsuit in an effort to block the 10 December auction.
