Ranch Coulee
Ranch Coulee is a field in North Dakota, operated by Rockport Energy Solutions LLC (derived).
Converted: Converted from the source's figures (Aug 2025–Jul 2026). 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).

Rounded to the nearest 10 below 1,000, the nearest 100 below 10,000 and the nearest 1,000 above that.

The network
From owner to landfall. Links without their own label have their source in the column heading; curated and derived links are labelled at the link.
- The colour shows the content:
- Gas
- Oil
- Condensate
- CO₂
- Oil and condensate
- The line shows the source:
- pipeline in NDIC data
- curated, with the source at the link
- possible onward route, not measured flow
- planned or not in service
The links show direction, not volume.
NDIC does not publish ownership shares, only the operator per well.

Notes
- Operated production in July 2026 (operator per well at NDIC, not an ownership share): ROCKPORT ENERGY SOLUTIONS LLC: 3 wells, 11,973 barrels of oil (79.9%); DEVON ENERGY WILLISTON, L.L.C.: 1 well, 2,096 barrels of oil (14.0%); CONTINENTAL RESOURCES, INC.: 2 wells, 541 barrels of oil (3.6%); ENERPLUS RESOURCES USA CORPORATION: 1 well, 368 barrels of oil (2.5%). The shares of the field's oil are calculated by OESA from the well rows.
- NDIC gives the operator of each well, not ownership shares. The companies' part of the production is therefore operated production, not ownership, and it is never treated as a share. A field gets an operator (marked derived) only when one company operates the wells with more than half of the field's oil in the latest month. When other companies have confidential wells in the field, it is not known who has the most. The oil sold (NDIC's Runs column, which is given for all wells, including the confidential ones) is then used instead, and this is stated at the field. If that does not show anyone with more than half either, the field is shown without an operator. The companies are listed with their names as NDIC writes them, and they are not linked to groups.
- The production is from NDIC's Monthly Production Report (Excel, one file per month, August 2025–July 2026), summed per field over the wells with figures: oil in barrels and gas in Mcf as NDIC gives them (the gas is produced gas, including gas that is flared). Each month is the Excel file as NDIC published it. NDIC states that later amendments are only in the PDF editions, so earlier months may differ slightly from them. Wells in WILDCAT (outside designated fields) and the oil in the SkimmedCrudeRecovery sheet (recovered at disposal wells) are not fields and are not included.
- Confidential wells are in the file without production figures (Oil, Gas, Wtr, Days and Flared are NULL), and NDIC withholds their production. For them NDIC gives only the oil and gas sold (Runs and GasSold). In July 2026 this applied to 255 of 22,466 wells. Fields with such wells show the sum of the reported wells, and this is stated at the field. For the operators the confidential wells are counted separately, and the sums there are marked «too low»; a figure NDIC withholds never becomes 0. The oil sold is only used to derive the operator where the production figures are not enough. NDIC's state totals in the PDF edition of the report are therefore higher than the sum of the fields here, and OESA shows no total for North Dakota as a whole.
- The fields in North Dakota are not in the map layers. The point for a field is the centre of the well positions NDIC gives, calculated by OESA, and it says nothing about the field's extent.
- Owners: NDIC does not publish ownership shares, only the operator per well.
- Status: NDIC gives no status for the field.
- Position: The point is the centre of 7 wells at NDIC, calculated by OESA.
- Derived operator: NDIC gives the operator per well, not per field. OESA shows as operator the company operating the wells with more than half of the field's oil in NDIC's Monthly Production Report for July 2026 (gas when the field has no oil). It is not an ownership share.
