Robertson N Field Geology & Production

The Robertson N field sits in the Permian Basin (Central Basin Platform Clearfork). The field has been producing oil since 1944 — a continuous production history spanning 82+ years. Modern operating consolidation under the Robertson (Clearfork) Unit framework has stabilized field-level production through pressure maintenance, waterflood, and (where applicable) CO2 enhanced oil recovery (EOR) operations.
