These modelling techniques are applied to the simulation of several important aspects of CO2 storage, which include optimizing total trapping through water injection, assessing the security of residual trapping with regards to leakage through...

... and resuming water injection. Experiments are carried out at temperatures of 30 and 35 °C, and water injection rates between 1 and 50 feet per day, to recover heavy oils with viscosities of 1500 to 2000 cP. Carbonated water used in these experiments is prepared by dissolving CO 2 in 1% wt. NaCl brine over 48...

Currently, oil-cut is about 0.5% and a clear decline trend has been established in oil-cut and oil rates as functions of cumulative oil produced (Figure 2). West Drumheller D2A This pool has...

... where waterflood is not a preferred option. Candidate reservoirs for this mode of gas injection could be tight, contain water sensitive clays (low water injectivity), overlain by gas caps, or contain initial mobile gas saturation. In the past, several gases (N2, CH4, CO2, flue, waste acid or tail gases...
