A mineral owner's guide to Denbury Onshore — operator of 5 of the top 20 producing Mississippi mature/EOR field units.
Quick answer
Denbury Onshore is the largest mature/EOR operator in Mississippi — 5 of the top 20 producing units. All Denbury Mississippi positions are Jackson Dome CO2 floods on the "Green Pipeline" / NEJD CO2 pipeline system. ExxonMobil acquired Denbury Resources in November 2023; the operator-of-record migration from "Denbury Onshore" to ExxonMobil branding is in progress at Mississippi state filings (one ExxonMobil Low Carbon Solutions well already visible in the data). Operator-side Jackson Dome CO2 supply is the binding economic constraint on the Denbury Mississippi EOR portfolio.
