Effect of relative permeability on the numerical simulation of the steam stimulation process
Thermal numeric simulators have been used to predict the performance of the steam stimulation processes. The experience is that room temperature relative permeability curves measured on extracted core samples need to be adjusted to match field performance. This work describes a study which was conducted to observe the effects of temperature on initial water saturations and residual oil saturations. A preserved core was mounted, stressed back to reservoir conditions and saturated with live reservoir oil, then waterfloods and oil floods were run at reservoir and elevated temperatures. Two single cycle simulations were run. Both sets of simulations used temperature functional relationships for the residual oil saturations and connate water saturations. The simulation which used the preserved core relative permeabilities resulted in matching the water production much closer than the simulation using extracted core relative permeabilities. 14 references.
