Bell Creek Test Site - Transportation and Injection Operations Report
"The PCOR Partnership, which is led by the Energy & Environmental Research Center (EERC), is working with Denbury Onshore LLC (Denbury) to study CO2 storage associated with a commercial enhanced oil recovery (EOR) project at the Denbury-operated Bell Creek oil field located in southeastern Montana. The CO2 for the project is sourced from the ConocoPhillips Lost Cabin Gas Plant and the ExxonMobil Shute Creek gas-processing facility, both of which are in Wyoming. The Lost Cabin CO2 is pressurized to a maximum pressure of 15.2 MPa (2200 psi) and transported through the 373-km (232-mi) Greencore pipeline to the Bell Creek field. The Shute Creek CO2 enters the Greencore pipeline through the Anadarko pipeline tie-in to the Greencore line. The Bell Creek EOR facility follows a scheme in which the water and CO2 that are separated from the oil are reinjected. Water is disposed of in a deeper formation or is used to pressurize portions of the field prior to CO2 injection, to continue water flood operations, or during WAG (water alternating gas) activities. Fluids from the individual wells are transported through flow lines and enter the header system of the production manifold in the manifold building. From the production manifold, the commingled stream flows to the process building for separation. The oil piped to oil storage and sales tanks. The water is piped to temporary water storage tanks prior to being pumped back to the field for reinjection. The CO2 is piped to the compressor building. Following pressurization, the CO2 discharges back to the manifold building where it is combined with the purchase CO2 for reinjection into the oil reservoir. Water and CO2 are distributed to the field through injection manifolds.The methods used by Denbury to plan, construct, and operate the Greencore pipeline for EOR may also apply to CO2 transportView/Download Document
