# Bridgeport Field Mineral Rights — Lawrence County, Illinois

The Bridgeport Field is a long-tenured, cross-county oil field spanning Lawrence and Crawford counties in the Illinois Basin, operated by multiple private operators using continuous waterflood production methods. The field produces from Mississippian-age reservoirs (Cypress and Aux Vases sandstones) and exhibits the classic Illinois Basin profile: small monthly royalty checks sustained over decades. Many mineral interests are inherited multiple generations deep, with original leases dating to the early 1900s, and out-of-state heirs are common.

## Key Takeaways

- **Cross-county field structure**: Bridgeport Field spans the Lawrence-Crawford county boundary in southeastern Illinois, with multiple long-tenured private operators managing production.
- **Mature waterflood operations**: The field has been on continuous waterflood for decades, producing 3-7% annual decline rates typical of stable Illinois Basin fields with 15-30+ years of remaining reserve life.
- **Mississippian reservoir production**: Primary producing formations are Cypress Sandstone and Aux Vases Sandstone, both Mississippian-age Illinois Basin reservoirs.
- **Multi-generational ownership common**: Many mineral interests are inherited multiple generations deep with original lease bonuses paid in the early 1900s; out-of-state heirs are frequently involved.
- **Remote selling process available**: Buckhead Energy handles the entire purchase process remotely for out-of-state owners, including free offers, notarized deeds, county recording, and same-day wire payment.
- **Valuation factors**: Direct buyers use 9-13% discount rates for stable waterflood cash flows and consider operator quality, decline rates, reserve life, and potential CCS/45Q optionality from underlying Mt. Simon Sandstone formations.
- **Indiana Dormant Mineral Act considerations**: The 20-year Dormant Mineral Act creates urgency for absentee owners on cross-border Illinois Basin fields.
