What this lot offers
The properties in this lot, by spacing unit. Six units pay on the tract; one takes in both of its 40 acre cells and five take in one.
| # | Unit | State and County | Unit basis | Wells | TRP tracts | NMA in unit | Paid NRI allocated to tract |
|---|
Units are the wellbore spacing units the operator pays on, read from the ECMC Form 2 (approved permit) unit configuration of each well on Nov 9, 2026; none carries a spacing order number. The TRP unit code (CO-xxxx) is the seller’s reference. The paid NRI is the decimal on the operator’s pay lines for each well (pay detail, Feb to Jul 2026 production). NMA in unit is the part of the tract’s NMA that lies inside the unit (0.9937 for both cells, 0.4969 for one) and does not add across rows. Lot total: 1 tract, 0.9937 NMA, 0.9937 NRA.

The tract is under one oil and gas lease, dated Apr 21, 1970 and recorded Jun 17, 1970 at Weld County Rec. No. 1549382 (Book 627), with a one-eighth royalty, and is held by production. NMA is as carried by the seller. NRA is (royalty ÷ 12.5%) × NMA. The N2SE4 is two 40 acre cells, the NWSE and the NESE, each taken as carrying half of the NMA (0.4969). The operator’s paid decimals back into 0.985 to 0.989 NMA for the tract, 0.4% to 0.9% under the seller’s figure, so every well pays slightly below the calculated decimal.
04 · Wells by unit
12 producing wells across six units
Select any well to open its card. The six units hold 12 wellbores with a current TRP line, all producing per ECMC. Each well is grouped under the unit that pays it, with the unit basis and the unit size. Each card shows the well’s paid NRI and the calculated NRI (tract NMA on the 40 acre cells in the unit ÷ unit acres × royalty). First production is the first month Enverus shows oil or gas; volumes are gross 8/8ths, March to August 2026.

- Why listed
- The Achziger Harry N #1 (API 05-123-10127, NESE of Sec 15) and #2 (API 05-123-10128, NWSE of Sec 15) are 1981 Sussex verticals on the tract, on 40 acre units, operated by K.P. Kauffman Company. ECMC shows both producing (status date Mar 1, 2026). The last payment received on either well was on the Apr 20, 2023 check, for production through Dec 2022. The amount below is everything received on both wells from Jul 2016 through that check; most of the payments were made on combined #1-2 lines and are not split between the two wells. Both wells are on the lands in this lot and are included in the interest offered; proceeds are divided at the effective date of the assignment.

Of the amount shown, $92.94 is on check lines and $68.33 is from the seller’s monthly receipt records with no check number; up to about $5 of the two may overlap.

Their last paid production month was Apr 2018. Source: operator check detail and seller receipt records; status from the ECMC scout cards, read Nov 9, 2026.
Status codes (ECMC, read Nov 9, 2026): PR producing. Interval is the Enverus producing interval; six-month volumes are Enverus monthly production (Mar to Aug 2026).

Calculated NRI: tract NMA on the 40 acre cells in the unit ÷ unit acres × royalty; all twelve wells pay 0.4% to 0.9% under it. Unit lands: ECMC Form 2 unit configurations, read Nov 9, 2026.

Method: the tract legal was drawn as an aliquot part of the BLM CadNSDI section polygon (BLM PLSS). Quarter and quarter-quarter lines are drawn at the midpoints of the BLM section corners, so they are close to, but not the same as, surveyed aliquot lines. Unit lands are from the ECMC Form 2 unit configurations; the tract is in a unit when its legal overlaps the unit lands.
