This Open-File Report presents the results of compositional simulations of CO2 floods of the Monument Butte Northeast unit and the Glen Bench field. Both fields produce oil from the Tertiary Green River Formation and both are currently in water flood. The Glen Bench field in the eastern Uinta Basin is an extension of the Wonsits Valley and Red Wash fields. Monument Butte Northeast is central Uinta Basin, is a waterflood unit within the Greater Monument Butte field.

The simulation study is a preliminary investigation of the CO2 enhanced oil recovery (EOR) potential. The study attempts to: (1) estimate the post waterflood incremental oil recovery for the two fields using CO2 injection and water-alternating-gas injection, (2) determine CO2 utilization factors, and (3) determine the CO2 sequestration potential of EOR for the fields.

Crude oil analysis was performed using the simulated distillation procedure on a gas chromatographic column, and minimum miscibility pressures were calculated. All simulations were performed using the compositional simulator GEM.
