... and to test steam injectivity in the First Eocene reservoir. The SST was conducted in First Eocene C Zone/Steam Zone 3 and successfully proved sustained injectivity using steam generated from the produced water. The SST was a pre-lude to a multipattern steamflood pilot known as the large-scale pilot (LSP...

... of steam into a reservoir. The reservoir is divided into six regions: undisturbed zone, cold-liquid zone, hot-liquid zone, steam zone, hot-water drive, and cold-water drive. The size, saturation, and movement of each zone, or bank, is calculated from a fractional-flow characterization of the reservoir...

...C.L. Hearn Channeling is particularly detrimental to the recovery in a steam drive if the main recovery mechanism is oil distillation in the steam zone. The El Dorado pilot test suggests that a steam drive would not, in general, be economical for tertiary recovery in reservoirs where channeling...

The method assumes that during the injection phase oil is displaced from the steam zone until some residual value of oil saturation is attained. During the production phase oil is snowed to flow back across the outer radius...
