Experimental and Numerical Studies on Multiple Well Pairs SAGD PerformanceWang, Xinkui 11 1900 (has links)
A laboratory experiment and a numerical simulation of a dual well pair SAGD process with live bitumen were conducted to examine operating strategies on the recovery performance of a multiple well pair SAGD process.
The experiment was successfully carried out under such operation strategies as injecting steam into one well pair while producing from both producers after chambers mergence to sweep the oil between the two well pairs. The experimental results showed high oil recovery from the transition region between the two well pairs with these operation strategies. Numerical simulation matched reasonably well experimental results, which indicated that the numerical model captured the key mechanisms of the dual well pairs experiment. The improved SAGD process behaviour and performance was demonstrated in terms of faster oil production, enhanced solution gas production, and accelerated adjacent chambers communication in the experimental and numerical studies.
These operation strategies could be applied in the multiple well pairs SAGD and enhance SAGD performance after steam chambers merge between adjacent well pairs. / Petroleum Engineering

Effect of oil sands slurry conditioning on bitumen recovery from oil sands oresQiu, Longhui 11 1900 (has links)
The effect of slurry conditioning on bitumen recovery and bitumen froth quality has been studied by using three oil sands ores tested with a laboratory hydrotransport extraction system (LHES) and a Denver flotation cell.
Tests with the LHES show that an increase in slurry conditioning time yielded a lowered bitumen recovery for a long flotation time (30 min). Longer slurry conditioning time led to a better bitumen froth quality regardless of flotation time. However the over conditioning could be compensated by higher conditioning temperatures and higher slurry flow velocities.
Tests with the Denver flotation cell show that the increase in slurry conditioning time resulted in a higher bitumen recovery and a better bitumen froth quality for both good and poor processing ores for a shorter flotation time of 5 min. For a longer flotation time of 20 min, increasing slurry conditioning time had little impact on bitumen recovery but led to a slightly better bitumen froth quality for the good processing ore whereas no effect on bitumen froth quality of the poor processing ore.
Results also show that higher slurry temperatures and stronger mechanical energy input were beneficial to both bitumen recovery and bitumen froth quality for all three oil sands ores tested on both devices. / Chemical Engineering
