In pursuit of a “$4 trillion industry” funded by tax credits and energy consumers, Exxon tarnished the corporation’s impressive Gulf of Mexico legacy by acquiring oil and gas leases solely for carbon disposal purposes (see caption above). That gambit and Repsol’s copycat strategy have apparently failed.
On June 29, 2026, Energy Intelligence reported that Exxon had begun relinquishing those leases. Kudos to those in the Administration who refused to buckle under pressure from lobbyists seeking to convert the leases to authorize carbon disposal.
That said, this sad chapter in OCS program history may not be over. 94 of the disposal leases have yet to be relinquished. Here is the current status of the improperly acquired leases:
- All 36 of the Repsol’s Sale 261 leases were relinquished effective 2/19/2026.
- All 69 of Exxon’s Sale 259 leases were relinquished effective 6/11/2026.
- None of Exxon’s 94 Sale 257 leases have been relinquished to date. Perhaps these leases are being held as a hedge in case there is another legislative end run or a policy decision that would facilitate conversion of the leases, or for tax/accounting purposes? As things stand, the leases expire in Oct. 2027.
Exxon and Repsol attempted to gain an unfair advantage by acquiring their preferred disposal leases without competition and before leasing and regulatory processes had been established. One could argue that they were fortunate to have avoided criminal penalty consideration given that they knowingly and willfully violated the terms of the sale notices.
The companies will lose their bonus payments which amounted to approximately $25 million for Exxon and $4 million for Repsol. They have also been paying rental fees of $10/acre/year for the Sale 259 and 261 leases, and $7/acre/year for the Sale 257 leases.
Lastly, one company was directly affected by the improper bidding. Focus Exploration was a second bidder for one of the blocks acquired by Exxon in Sale 259 (red in map below). Presumably, Focus was interested in acquiring the tract for oil and gas exploration purposes, but their bid was a bit lower than Exxon’s. Should Focus be compensated in some manner?
