Paper presented at the SPE Canada Heavy Oil Technical Conference, February 15–16, 2017
Paper Number: SPE-185002-MS
... Abstract Relative permeability plays a significant role in predicting oil rate and ultimate oil recovery factor. The literature reveals that same set of relative permeability is often used to predict the ES-SAGD performance regardless of not only the downhole operating temperature but also...

... ( Mukhametshina and Hascakir 2014 ), due to the subsequent permeability reduction. Better cumulative oil recoveries for ES-SAGD experiments is partly due to the reduced asphaltene-clay associations in these cases. Another observation is that for the outside steam chamber zone, asphaltene- clay interaction is more...
