The Slaughter Consolidated Unit is one of the most active long-tenured oil units in west Texas Permian Basin. With 43 historic wells, an oldest spud date of 1997, and recent monthly production of 15,235 barrels of oil (February 2026), the unit demonstrates the long-tail production profile that characterizes mature unitized oil operations in the Permian Basin (Northwest Shelf).
OXY operates the Slaughter Consolidated Unit as part of its Slaughter field complex — one of the largest Permian Basin Northwest Shelf positions.
The TStar field sits in the Permian Basin (Northwest Shelf). The field has been producing oil since 1997 — a continuous production history spanning 29+ years. Modern operating consolidation under the Slaughter Consolidated Unit framework has stabilized field-level production through pressure maintenance, waterflood, and (where applicable) CO2 enhanced oil recovery (EOR) operations.

Mineral interests in the Slaughter Consolidated 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 Slaughter Consolidated Unit interests are inherited multiple generations deep, with original lease bonus paid in the 1930s-1960s era. Current Slaughter Consolidated Unit mineral owners frequently include heirs spread across multiple states.
Direct buyers value Slaughter Consolidated 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 (Northwest Shelf) 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
