The Denver-Julesburg (DJ) Basin is the primary oil-producing basin in Colorado, centered in Weld County northeast of Denver. The Niobrara Formation and underlying Codell Formation are the primary horizontal targets, and the basin has been transformed by modern drilling and completion techniques. We actively buy mineral rights, royalty interests, NPRI, and ORRI across the DJ Basin, including both core Weld County acreage and the outer-edge counties.

The Niobrara Formation is a chalk formation deposited during the Late Cretaceous period. It contains up to four productive benches (A, B, C, and D), each separated by marl intervals. Below the Niobrara sits the Codell Formation, a sandstone that is also productive in much of the basin. The total productive section spans approximately 400 feet. The Niobrara sits at depths of 6,500 to 8,000 feet in the DJ Basin, which is shallower than most other major shale plays. The relatively shallow depth keeps drilling costs lower, which supports favorable well economics. Multi-bench development across the Niobrara benches and the Codell is standard practice in the core of the basin.
Civitas Resources (formed from the merger of Bonanza Creek, Extraction, and Crestone Peak) is the largest pure-play DJ Basin operator. Oxy holds a large position through its acquisition of Anadarko Petroleum. PDC Energy (now Chevron) and Great Western Petroleum round out the major players. The DJ Basin has seen significant operator consolidation in recent years.
DJ Basin mineral values are driven by the number of productive Niobrara benches and Codell development, operator activity, and location within the basin. Core Weld County acreage with multi-bench development commands the highest valuations. Acreage in the outer-edge counties (Adams, Arapahoe, Larimer, Boulder) generally supports lower valuations due to thinner formation development and additional regulatory considerations under SB 19-181. Despite the regulatory environment, the DJ Basin remains one of the most actively drilled plays in the Rocky Mountain region.
Additional counties we cover within the DJ Basin, sorted by recent oil and gas activity:
SB 19-181 changed the mission of Colorado's regulatory body and gave local governments more authority over surface use. Permitting timelines have increased and setback requirements have been imposed near occupied buildings. These changes have modestly reduced the development pace in some areas, which can affect mineral valuations. However, the DJ Basin continues to be actively drilled, and the bill did not change underlying mineral property rights.
Up to four Niobrara benches (A, B, C, and D) are productive in the DJ Basin, plus the underlying Codell Formation. Multi-bench development is standard in the core of the basin, with operators drilling wells in multiple formations from the same pad. This stacked-pay potential is a key driver of DJ Basin mineral values.
Core Weld County acreage is the most valuable, particularly in the areas with the highest Niobrara thickness and the most active operator drilling programs. Adams and Arapahoe counties can also be valuable but face additional regulatory scrutiny due to proximity to the Denver metro area. Larimer, Boulder, and Broomfield counties are on the outer edge of the play and generally command lower valuations.
