# Salem Consolidated Field Mineral Rights — Marion County, Illinois

## TL;DR

Salem Consolidated is one of Illinois's largest cumulative oil producers with over 250 million barrels extracted from Mississippian-age reservoirs via continuous waterflood operations. Multiple long-tenured private operators manage this mature Illinois Basin field, which delivers the region's characteristic long-tail royalty profile: small monthly checks for decades. Many mineral interests are inherited multiple generations deep with original leases dating to the early 1900s, and out-of-state heirs are common.
