# Olney Consolidated Field Mineral Rights in Richland County, Illinois

**TL;DR:** The Olney Consolidated field is a long-tenured Illinois Basin producer in Richland County operating under continuous waterflood by multiple private operators. The field produces from Mississippian-age reservoirs (Cypress, Aux Vases, McClosky) and generates the characteristic long-tail royalty cash flow profile of mature Illinois Basin operations — small monthly checks spanning decades. Many mineral interests are inherited multiple generations deep with original leases dating to the early 1900s.

## Key Takeaways

- **Long-tenured waterflood operation**: Olney Consolidated has been on continuous waterflood for decades, operated by multiple experienced private Illinois Basin operators
- **Mississippian-age production**: Primary producing formations include Cypress Sandstone, Aux Vases Sandstone, and McClosky Limestone
- **Multi-generational ownership**: Many mineral interests were originally leased in the early 1900s and have passed through multiple generations of heirs, often scattered across states
- **Predictable decline profile**: Illinois Basin waterflood fields typically exhibit 3-7% annual decline rates with 15-30+ years of remaining reserve life
- **Remote transaction capability**: Out-of-state mineral owners can complete sales entirely remotely through deed execution, county recording, and wire transfer
- **CCS sequestration potential**: Select Illinois Basin acreage may have Mt. Simon Sandstone carbon capture and storage potential beneath producing zones (45Q tax credit opportunities)
- **Cross-border complexity**: Indiana's 20-year Dormant Mineral Act creates urgency for absentee owners on fields near the Illinois-Indiana border

## Page Highlights

**Field Characteristics**: The Olney Consolidated field in Richland County is managed by multiple long-tenured private operators using continuous waterflood recovery mechanisms. It exemplifies the Illinois Basin's mature production profile with consistent, predictable cash flows over multi-decade timeframes.

**Producing Formations**: Production comes from Mississippian-age reservoirs including Cypress Sandstone, Aux Vases Sandstone, and McClosky Limestone — all part of the broader Illinois Basin geological sequence that has supported commercial oil production since the late 1800s.

**Ownership Structures**: Mineral interests typically exist as producing royalty interests (monthly revenue share), non-producing mineral interests (fee ownership outside active zones), overriding royalty interests (ORRI), or non-participating royalty interests (NPRI). Multi-generational inheritance is common, with heirs often distributed across multiple states.

**Valuation Framework**: Buyers use discounted cash flow models incorporating 3-7% annual decline rates, 15-30+ year reserve life, 9-13% discount rates for stable waterflood cash flows, operator quality assessments, and potential CCS/45Q optionality where Mt. Simon Sandstone sequestration potential exists beneath producing zones.

**Sales Process**: Buckhead Energy handles remote transactions for out-of-state owners through free written email offers, notarized deed execution in the owner's home state, recording with Richland County clerk, and same-day wire transfer upon recording completion.

**Regional Context**: The field is part of the Illinois Basin — one of North America's longest-producing oil and gas regions with continuous production since the late 1800s. Other major Illinois Basin fields include Clay City Consolidated, Salem Consolidated, Loudon, New Harmony Consolidated, Mt. Carmel, Lawrence, Main Consolidated, Bridgeport, and Westfield.
