Heidelberg East Field Unit Mineral Rights — Jasper County, Mississippi

Heidelberg East Field Overview

About the Heidelberg East Field

The Heidelberg East field is one of the long-tenured oil-producing fields in Mississippi. With 46 historic wells, an oldest spud date of 1943, and recent monthly production of 49,508 barrels of oil (January 2026), the field demonstrates the long-tail production profile that characterizes mature Mississippi oil operations.

Denbury Onshore (the operating subsidiary of Denbury Resources, acquired by ExxonMobil in November 2023) operates the Heidelberg East field as part of the Jackson Dome CO2 EOR portfolio. Heidelberg East is one of the highest-rate CO2 EOR fields in Mississippi.

The field is on the Denbury "Green Pipeline" / NEJD CO2 pipeline system from Jackson Dome — operator-side CO2 supply is the binding economic constraint.

Mississippi Mature-Field Production Context

Mississippi's top 20 producing units (by recent monthly oil production) collectively produce approximately 237,000 barrels per month — about one-third the size of Texas's top 20 units. The Mississippi field landscape is dominated by long-life waterflood and CO2 enhanced oil recovery (EOR) operations, with a substantial concentration of fields fed by the Denbury Jackson Dome CO2 supply system. Jasper County is one of the more active producing counties in the state.

Mineral Interest Profile

Mineral interests on the Heidelberg East field typically take one of these forms:

Producing royalty interest — your tract's contribution to the field's monthly revenue, paid by the operator

Non-producing mineral interest — fee mineral ownership in a tract currently outside active producing zones

Overriding royalty interest (ORRI) — a royalty carved out of a working interest

Non-participating royalty interest (NPRI) — a royalty interest with no leasing or development rights

Many Heidelberg East field interests are inherited multiple generations deep, with original lease bonus paid in the 1940s-1960s era. Current Mississippi mineral owners frequently include heirs spread across multiple states.

Valuation Considerations

Direct buyers value Heidelberg East field mineral interests using a discounted cash flow approach with these key inputs:

Decline rate — typically 3-8% annual on long-life Mississippi waterflood / EOR fields

Remaining reserve life — often 15-30+ years on actively-maintained EOR units

Operator quality — long-tenured Mississippi EOR operators typically deliver predictable production

CO2 supply constraint — for Jackson Dome-supplied CO2 floods, operator-side CO2 supply is the binding constraint on EOR economics; this affects long-term reserve life projections

Discount rate — typically 9-13% for stable Mississippi unitized cash flows
