⚠ Decommissioning Comes BackLow threat

Chevron (CVX) — threat to the moat

Chevron paid $1.9 billion in 2023 to decommission fields it had already sold, because the buyers could not.

Selling an old field is supposed to end the obligation to clean it up. Chevron's risk factors warn that it may not: "transferred liabilities, including for decommissioning of previously divested assets, have returned and may continue to return to the company when an acquirer" defaults1.

Two charges that together cost $3.7 billion in one year.

This is not hypothetical. In 2023 Chevron took $1.9 billion in charges related to abandonment and decommissioning obligations for previously sold oil and gas producing assets in the U.S. Gulf of Mexico2. The buyer's balance sheet failed; the obligation came home.

The point for the moat is that the long life of oil assets runs both ways. The same decades that make a field valuable make its eventual removal a liability that outlives the owner who sold it, and a company with a century of divestitures has a long list of former fields.

The liability is written into Chevron's own history of selling. The company sold assets in Canada and the Republic of Congo in 20253 and 70 percent of its Haynesville interest4. Each sale moves an operating field to a buyer; if that buyer later fails, the clean-up bill can come back.

Charges for previously sold assets in the annual special items are the evidence to watch. Another year like 2023 would mean the portfolio's history is still being paid for.
