A gate-to-gate life cycle analysis (LCA) model was created to quantify the environmental impacts of the various processes associated with enhanced oil recovery. The following unit processes are accounted for in this analysis: injection and recovery, bulk separation and storage, gas separation, supporting processes, and land use. This analysis used an LCA approach for developing data, and EOR and gas processing. The energy and material flows for key processes within the gate-to-gate boundaries of the EOR site were calculated. These processes were then compiled in a model that scaled the flows between processes to arrive at an inventory of environmental burdens on a common basis (i.e., 1 barrel of crude produced via EOR). A briefing is also included with the report.
