Infrastructure needs at the SECARB “early” Cranfield test are different from many other CCS sites, because this test is strongly supported by the commercial activities of site host Denbury Onshore LLC. Commercial development by Denbury provided the substantive cost-share required to make the project viable. Denbury contributions fundamental for the project included the retrofit of the former Sonat natural gas pipeline from the Jackson Dome CO₂ source to the center of Cranfield Field, construction of distributory pipelines to take CO₂ to injection wells, and construction of roads and well pads that allowed access for drilling and maintenance of injection wells. In addition, as part of the EOR operations, Denbury constructed a CO₂ separation plant to increase pressure from pipeline pressure to field pressure and support CO₂ recycle, construction of production lines to bring oil, water, CO₂ and gas to the separation plant, and worked over plugged and abandoned (P&A) wells to retrofit them as producers. Producers were used by the SECARB project as monitoring points to observe flood. Denbury’s well test facility allowed monthly quantification of the volumes of fluids produced and reinjected.
