Smart-Well Technology at the SACROC CO2 EOR Project

Application of smart-field technologies to the SACROC Unit carbon dioxide enhanced oil recovery (CO2-EOR) project in Scurry County, Texas, was studied. A five-well pilot project in early 2005 demonstrated the ability of intelligent-well downhole flow-control valves to restrict or isolate the production of CO2 from breakthrough zones in production wells and to control the distribution of CO2 injection in injection wells. The objective is to reduce unnecessary cycling of CO2 between injectors and producers, improve sweep efficiency, increase oil production, and improve ultimate oil-reserves recovery. This is done with cost-effective, fit-for-purpose intelligent-well systems.
