Chevron U.S.A. Inc.

Leases

The leases where Chevron U.S.A. Inc. holds a share or is the operator. A share in a lease is not a field share.

Pipelines and plants

Pipelines, facilities and terminals where Chevron U.S.A. Inc. is the operator or an owner in the source.

Notes

• The shares are legal ownership shares at BOEM, not the company's reported production.
• The arrows show direction, not volume. The direction is the source's from → to for each pipeline. The source has no flow per pipeline. Pipelines without from and to in the source are shown without direction.
• BOEM's shares are record title shares per lease. They are not the participation shares in the unit agreements, which are not public, and not necessarily the working interests (operating rights). The fields therefore have no ownership shares; the shares are per lease, and production by share is calculated per lease.
• The ownership history is BOEM's own: each assignment has an effective date, and a share applies from that date until the day before the next change. Shares that ended before 2020 are not included.
• The leases in the Gulf of Mexico are included when they belong to a field in BOEM's field list or have production in Jun 2025–Jun 2026. 1176 leases with current owners, most of them in the exploration term, are not included in the overview.
• The production is BOEM/BSEE's OGOR-A figures per completion, summed per lease and per field for Jun 2025–Jun 2026: oil and condensate in barrels (bbl), gas in Mcf. The figures come three to four months after the production month, and BOEM marks the latest month as incomplete.
• The field operator is the operator BOEM/BSEE gives for the completions in the latest month. The lease operator is the designated operator. The operator and field of the installations are from BOEM's platform file (platmast).
• BOEM's pipelines end at an installation or at the boundary to state waters. The route onward to shore, the pipeline owners and the capacity are not in BOEM's data. Only active pipelines of at least 10 inches for oil, gas and condensate are included. The pipeline operator is the operator BOEM gives for the segment in the pipeline file (FACIL_OPERATOR, at the latest inspection). A pipeline is linked to an installation when BOEM's platform id in the pipeline file (platform name, area and block, for example “A MC 807”) equals the platform name without the nickname in brackets, area and block in the platform file (“MC 807 A (Mars)”), and the match is unique.
• The lease status (UNIT, PRODUCTION, INITIAL …) is BOEM's word from the map layer as of 26 Sep 2026. A field is shown as producing when OGOR-A has production from the field in Jun 2026.
• BOEM has no field outlines. The field's position is the centre of the blocks BOEM links to the field (Gulf of Mexico) or of the leases the field produces from (Pacific).
• The fields are named as in BOEM's list of nicknames. Fields without a nickname are shown with BOEM's field code (for example MC392), and in the Pacific BOEM gives only the field code (HONDO, DSCDRS).
• The share estimate per field is OESA's calculation: the record title share in each lease in the field, weighted by the lease's production from the field in oil equivalent (Jul 2025–Jun 2026), with the share that applied in each month. It is not the field's ownership and is not used in sums; the sums are calculated per lease.
