The Cedar Lake Unit is one of the most active long-tenured oil units in west Texas Permian Basin. With 173 historic wells, an oldest spud date of 1949, and recent monthly production of 30,437 barrels of oil (February 2026), the unit demonstrates the long-tail production profile that characterizes mature unitized oil operations in the Permian Basin.
OXY operates the Cedar Lake Unit as one of its long-tenured Permian Basin EOR positions in Gaines County.
The Cedar Lake field sits in the Permian Basin. The field has been producing oil since 1949 — a continuous production history spanning 77+ years. Modern operating consolidation under the Cedar Lake Unit framework has stabilized field-level production through pressure maintenance, waterflood, and (where applicable) CO2 enhanced oil recovery (EOR) operations.

Mineral interests in the Cedar Lake 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 Cedar Lake Unit interests are inherited multiple generations deep, with original lease bonus paid in the 1930s-1960s era. Current Cedar Lake Unit mineral owners frequently include heirs spread across multiple states.
Direct buyers value Cedar Lake Unit mineral interests using a discounted cash flow approach with these key inputs:
Decline rate — typically 3-8% annual on long-life unitized waterflood / EOR wells
Remaining reserve life — often 15-30+ years on actively-maintained units
Operator quality — well-maintained units (Occidental Petroleum (OXY) is established in west Texas Permian Basin) typically deliver predictable production
EOR upside — many Permian Basin units have CO2 EOR or other tertiary recovery upside not reflected in current production rates
Discount rate — typically 8-12% for stable unitized cash flows
