# Bridgeport Field Mineral Rights in Lawrence and Crawford Counties, Illinois

**TL;DR:** The Bridgeport Field is a long-producing Illinois Basin oil field straddling Lawrence and Crawford counties, operating under continuous waterflood since the early 1900s. Multiple private operators produce from Mississippian-age Cypress and Aux Vases sandstones, generating characteristic small monthly royalty checks over decades. Many mineral interests are inherited multiple generations deep, and Buckhead Energy offers direct purchase with remote transaction capabilities for out-of-state owners.

## Key Takeaways

- **Cross-county mature field**: Bridgeport Field spans Lawrence and Crawford counties in the Illinois Basin, operating under continuous waterflood for decades with multiple long-tenured private operators
- **Mississippian sandstone production**: Primary producing formations are Cypress Sandstone and Aux Vases Sandstone, typical of Illinois Basin mature fields
- **Multi-generational ownership**: Most mineral interests were originally leased in the early 1900s and have been inherited through multiple generations, often with heirs spread across multiple states
- **Long-tail cash flow profile**: The field produces small monthly royalty checks over 15-30+ year reserve lives with typical 3-7% annual decline rates on actively maintained waterflood units
- **Valuation inputs**: Direct buyers use discounted cash flow models incorporating decline rate, remaining reserve life, operator quality, 9-13% discount rates, and potential CCS/45Q value from underlying Mt. Simon Sandstone
- **Remote sale capability**: Out-of-state mineral owners can complete transactions entirely remotely through free written offers, notarized deeds, county recording, and wire transfer
- **Indiana Dormant Mineral Act urgency**: The 20-year Dormant Mineral Act creates particular urgency for absentee owners on cross-border Illinois Basin fields
- **CCS sequestration potential**: Selected Illinois Basin acreage has Mt. Simon Sandstone carbon capture and storage potential beneath producing zones, particularly in the Wabash Valley Resources hub area
