Recent monthly oil production: 250,000+ bbl
Recovery method: Waterflood + CO2 EOR pilots
The Fullerton Clearfork Unit is one of the largest unitized Clearfork operations in the Permian Basin Central Basin Platform. The Lower Clearfork carbonate is among the deeper, lower-permeability Permian targets, making it well-suited to long-life waterflood and CO2 EOR operations.
The Fullerton Clearfork Unit is operated by Crownquest Operating as one of the long-tenured unitized oil operations in the Permian Basin (Central Basin Platform). With first production dating to 1942 and recent monthly oil output of 250,000+ barrels, the unit demonstrates the long-tail production profile that characterizes mature unitized operations in the region.
The Fullerton field produces from the Clearfork (Lower) reservoir. Modern operating consolidation under the Fullerton Clearfork Unit framework has stabilized field-level production through waterflood + co2 eor pilots.

Mineral interests in the Fullerton Clearfork Unit typically take one of these forms:
Producing royalty interest — your tract's contribution to the unit's monthly revenue, paid by the operator
Non-producing mineral interest — fee mineral ownership in a tract currently outside active producing zones
Overriding royalty interest (ORRI) — a royalty carved out of a working interest
Non-participating royalty interest (NPRI) — a royalty interest with no leasing or development rights
Many Fullerton Clearfork Unit interests are inherited multiple generations deep, with original lease bonus paid in the early discovery era. Current Fullerton Clearfork Unit mineral owners frequently include heirs spread across multiple states.
Direct buyers value Fullerton Clearfork Unit mineral interests using a discounted cash flow approach with these key inputs:
Decline rate — slow, typical of long-life unitized waterflood / EOR wells
Remaining reserve life — long on actively-maintained units
Operator quality — Crownquest Operating is an established operator in the Permian Basin (Central Basin Platform)
EOR upside — Waterflood + CO2 EOR pilots operations can extend ultimate recovery beyond primary depletion estimates
Discount rate — market-based, reflecting stable unitized cash flows
