South Cross Unit Mineral Rights — Crockett County, Texas

Unit Overview

About the South Cross Unit

The South Cross Unit is one of the most active long-tenured oil units in west Texas Permian Basin. With 41 historic wells, an oldest spud date of 1961, and recent monthly production of 19,868 barrels of oil (February 2026), the unit demonstrates the long-tail production profile that characterizes mature unitized oil operations in the Permian Basin (eastern shelf).

OXY operates the South Cross Unit as part of its Crossett South field position — a long-tenured Permian Basin position in Crockett County.

Crossett S Field Geology & Production

The Crossett S field sits in the Permian Basin (eastern shelf). The field has been producing oil since 1961 — a continuous production history spanning 65+ years. Modern operating consolidation under the South Cross Unit framework has stabilized field-level production through pressure maintenance, waterflood, and (where applicable) CO2 enhanced oil recovery (EOR) operations.

Mineral Interest Profile

Mineral interests in the South Cross 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 South Cross Unit interests are inherited multiple generations deep, with original lease bonus paid in the 1930s-1960s era. Current South Cross Unit mineral owners frequently include heirs spread across multiple states.

Valuation Considerations

Direct buyers value South Cross 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 — well-maintained units (Occidental Petroleum (OXY) is established in west Texas Permian Basin) typically deliver predictable production

EOR upside — many Permian Basin (eastern shelf) units have CO2 EOR or other tertiary recovery upside not reflected in current production rates

Discount rate — market-based, reflecting stable unitized cash flows
