# Salem Limestone Mineral Rights in the Illinois Basin

The Salem Limestone is a Mississippian-age carbonate formation producing oil and gas across central and southern Illinois at depths of 1,500–2,800 feet. Best known for the historic Salem oil field in Marion County—one of the Illinois Basin's largest fields with over 250 million barrels cumulative production—the formation is increasingly being evaluated as a CO2 sequestration reservoir for carbon capture and storage (CCS) projects due to its porosity and confinement characteristics.

## Key Takeaways

- **Salem Limestone is a prolific Mississippian-age producer** in central and southern Illinois, typically drilled at 1,500–2,800 feet and often co-developed with Aux Vases and Cypress formations
- **The Salem oil field in Marion County was discovered in 1938** and peaked at over 100,000 barrels per day, with cumulative production exceeding 250 million barrels
- **Many Marion County mineral interests originated with 1930s landowners** and continue generating royalty income from ongoing waterflood operations
- **Emerging CCS interest:** the Salem is being evaluated as a potential CO2 sequestration reservoir in selected Illinois Basin carbon capture projects where porosity and confinement support storage modeling
- **Direct acquisition model:** Buckhead Energy purchases Salem Limestone mineral rights directly with no broker commissions, listing fees, or auction premiums for sellers
