Quick answer
Producing trend: Wasson San Andres (Permian Basin Northern Shelf)
Unit type: long-lived unitized waterflood / CO2 EOR unit
The Wasson ODC Unit (District 11) is a long-tenured oil unit in the west Texas Permian Basin. Its long-tail production profile is typical of mature unitized oil operations on the Wasson San Andres trend. For statewide context, see our Texas oil & gas production distribution page.
OXY operates the Wasson ODC Unit as part of the giant Wasson field complex — one of the largest CO2 EOR projects in U.S. history.
The Wasson field sits in the Permian Basin (Wasson San Andres trend). The field has produced oil continuously since the Wasson discoveries of the 1930s. Modern operating consolidation under the Wasson ODC Unit (District 11) framework has stabilized field-level production through pressure maintenance, waterflood, and (where applicable) CO2 enhanced oil recovery (EOR) operations.

Mineral interests in the Wasson ODC Unit (District 11) 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 Wasson ODC Unit (District 11) interests are inherited multiple generations deep, with original lease bonus paid in the 1930s-1960s era. Current Wasson ODC Unit (District 11) mineral owners frequently include heirs spread across multiple states.
Direct buyers value Wasson ODC Unit (District 11) 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 — well-maintained units (Occidental Petroleum (OXY) is established in west Texas Permian Basin) typically deliver predictable production
EOR upside — many Permian Basin (Wasson San Andres trend) units have CO2 EOR or other tertiary recovery upside not reflected in current production rates
Discount rate — market-based, reflecting stable unitized cash flows
