... of this study is that the vertical placement of the horizontal injector has a significant effect on oil recovery and lifecycle CO 2 retention. Placing the injector close to the bottom of the ROZ and the producers in the MOC resulted in the highest carbon sequestration. The optimized case improved CO 2...

... °F has been observed near wellbore and a temperature change of up to ~70 °F has been observed at the caprock. The temperature remains mostly unchanged as we move away from the injector. But the temperature changes observed near caprock directly above injection point is important since this reduces...
