An owner's guide to mineral rights on the Heidelberg East field — operated by Denbury Onshore in Jasper County, Mississippi.
Quick answer
County: Jasper County, Mississippi
Field: Heidelberg East
Operator: Denbury Onshore
Field type: Jackson Dome CO2 EOR flood
The Heidelberg East field is one of the long-tenured oil-producing fields in Mississippi, with 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 Jackson Dome-supplied 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.
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. For statewide aggregate drilling activity, see the Mississippi Drilling Activity Report.
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.
Direct buyers value Heidelberg East field mineral interests using a discounted cash flow approach with these key inputs:
Decline rate — slow, typical of long-life Mississippi waterflood / EOR fields
Remaining reserve life — long 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 — market-based, reflecting stable Mississippi unitized cash flows
