Gibson Unit

The Gibson Unit is a CO₂-enhanced oil recovery (CO₂-EOR) project located in the Permian Basin of West Texas, associated with carbonate reservoirs developed on the Northwest Shelf and Central Basin Platform trends. The unit produces primarily from Permian-age carbonate formations, typically including intervals within the San Andres or Clearfork stratigraphic sequences common across large Permian tertiary recovery projects. After primary depletion and secondary waterflooding, the field transitioned to miscible CO₂ injection to mobilize residual oil trapped within layered dolomitized carbonate flow units and fracture networks. The project leverages the extensive Permian CO₂ pipeline network supplying naturally sourced CO₂ for tertiary recovery. Similar to neighboring large-scale CO₂ floods such as Wasson, SACROC, and Cogdell, the Gibson Unit represents a mature tertiary redevelopment designed to increase recovery factors while storing injected CO₂ within structurally confined carbonate reservoirs.
