✦ Deepwater Gulf of AmericaNarrow moat

Chevron (CVX) — the future bets

Chevron's Gulf of America fields are operated, long-lived and expensive, and the last big Gulf project it built ended in a write-down.

Chevron's other offshore growth is in American waters, where it operates. In 2025 it started and ramped up production at the Anchor, Ballymore, Stampede and Whale fields in the deepwater Gulf of America1, and in the first quarter of 2026 it announced the Bandit discovery2. Hess added about 31 thousand barrels a day of Gulf production3.

Offshore now takes more of the upstream budget than shale.

The money is committed. Chevron's 2026 plan puts about $7 billion into offshore developments, primarily supporting growth in Guyana, the Eastern Mediterranean and the Gulf of America4. American upstream capital spending was $9,777 million in 20255.

Deepwater is the opposite of shale. A shale well pays back quickly and declines quickly; a deepwater field costs years of spending before first oil and then produces for a long time. Anchor, in the Green Canyon area, uses what Chevron calls high-pressure subsea technology to reach deeper reservoirs6.

It also carries a history. The 2019 impairment of $8.17 billion was primarily associated with Appalachia shale and Big Foot7, a Gulf of Mexico project. Deepwater write-downs happen when fields disappoint after the money is spent.

Hess's Gulf production of about 31 thousand barrels a day8 adds to fields Chevron already runs, which is where a non-operated Guyana stake cannot help: in the Gulf, Chevron controls the pace.

The test is whether the new fields lift American upstream earnings per dollar of capital. With segment assets of $84,559 million at the end of 20259, a return that stays near the 2025 level would mean the new fields replaced old ones rather than adding to them.

The number that tests this moat

United States upstream capital expenditure
$9,777M (2025)

The spending the offshore ramp and shale need; rising capex without rising US earnings would show the new fields replace rather than add.
