Numerous injection-production strategies involving water injection and hydrocarbon production with gas cycling, were examined. Fluid saturation distributions were studied for a three-layer reservoir. These shoved...

... in the Tia Juana field in Venezuela [2] is reported to produce average oil rates of 700 bpd per well pair from first year's operation. Although SAGD is effective in producing bitumen and heavy oils, it requires large quantity of heat to heat the whole chamber to saturated steam temperature and the heat...
