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. UNMIG reports production per concession, and the entity here is the concession. Gas is in Sm³ as UNMIG gives it; oil and gasolina (under NGL) are given in kg and shown in tonnes (kg divided by 1,000).
Estimate: 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. 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.

Concessions
The concessions the field lies in, with the licensees as the source states them. A share in a concession is not a field share.
ConcessionsUNMIG · 8 Oct 2026
| Name | Type | Operator | Licensees |
|---|---|---|---|
| Tertiveri | concession (concessione di coltivazione) | ENI | ENI 70%, GAS PLUS ITALIANA 30% |
Notes
- The field in the concession according to UNMIG's list of wells: Roseto-Montestillo.
- Latest decision on shares at UNMIG: «Cambio intestazione quota» (1 Mar 2013). UNMIG does not give the shares before the decisions.
- UNMIG states ownership shares and production per concession (concessione di coltivazione), not per field. OESA shows each concession as one entity with the fields from UNMIG's list of wells, and equity production is calculated per concession.
- Gas is in Sm³ as UNMIG gives it. Oil and gasolina are given in kilograms and are shown here in tonnes (kg divided by 1,000). Oil is not converted to Sm³ or oil equivalent because UNMIG does not state the density, so concessions with oil are not included in sums in oil equivalent. Gasolina (natural gasoline from gas processing) is shown under NGL. UNMIG also reports GPL (Gorgoglione), but not the unit for GPL, so GPL is not included.
- The shares are the current shares in UNMIG's list of titles (as of 30 Sep 2026). UNMIG gives the dates of decisions on shares, but not the shares before the decisions. Where such a decision was made on or after 1 Aug 2025, the shares are not used in calculations for the period with production figures.
- History: UNMIG only gives the current shares. OESA stores the shares from the date given for each.
