Ridgewood Energy Gulf of Mexico Oil and Gas Fund, L.P.
Ridgewood Energy Gulf of Mexico Oil and Gas Fund, L.P. holds stakes in 4 fields on the US Outer Continental Shelf. The map shows how the fields connect to facilities, pipelines and landfall.
- Calculated equity production, last 12 months (BOEM), 7 of 8 fields and licences with production
- 0.028 million Sm³ o.e.
- Estimate · Jul 2025–Jun 2026 · BOEM · 7 Oct 2026
Estimate: Calculated by OESA, not figures from the company: for each field (or each licence where both the shares and the production are per licence) the share that applied in each month is multiplied by the production from BOEM (Jul 2025–Jun 2026), converted to oil equivalent and summed over 7 fields and licences. Oil equivalent by the Norwegian Offshore Directorate's rule: oil, condensate and NGL in Sm³ count equally, 1,000 Sm³ of gas = 1 Sm³ o.e. and 1 tonne of NGL = 1.9 Sm³ o.e. Converted from barrels: 1 barrel = 0.158987 m³ (42 US gallons). The source's barrels are at 60 °F and Sm³ at 15 °C; the difference is under 0.1%. Converted from Mcf: 1 Mcf (60 °F, 14.73 psia) ≈ 28.33 Sm³ (15 °C, 101.325 kPa). Not included in the sum: 1 field or licence where the source's shares cannot be used for calculation. G27982: BOEM gives different shares for different parts of the lease (the owner groups). The source does not say which part the production comes from, so the share is not used in calculations. The figure applies in the United States and is not the company's global production. Per day: Sm³ o.e. × 6.29 barrels per Sm³ divided by the number of days in the period. Rounded to the nearest 10 below 1,000, the nearest 100 below 10,000 and the nearest 1,000 above that.

Notes
- The shares are legal ownership shares at BOEM, not the company's reported production.
- 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 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.
