Field · the network on the UK Continental Shelf
Wareham
Wareham is an oil field on the UK Continental Shelf, operated by Perenco Oil & Gas.
Estimate: Converted from the source's figures (Jul 2025–Jun 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. Estimate: the source gives m³ without reference conditions, and the figure is treated as Sm³. The error can be up to about 5%.

Estimate: the source gives m³ without reference conditions, and the figure is treated as Sm³. The error can be up to about 5%. 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.

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 NSTA 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.
NSTA gives shares for onshore fields only per licence; a licence share is not a field share.

Notes
- The production is NSTA's PPRS figures per field and month: oil and condensate in m³, gas (associated and dry gas combined) in 1,000 Sm³. Fields reported in parts are the sum of the parts. Coal mine vents are not included.
- The operator is NSTA's organisation group (for example APACHE CORPORATION), not the legal company holding the share. NSTA does not link installations and pipelines to fields; they are listed under the operator. Only pipelines in use carrying oil, gas, condensate, mixed hydrocarbons or CO₂ are included.
- Owners: NSTA gives shares for onshore fields only per licence; a licence share is not a field share.
