2Crude, you said, "sor's generally increase with their installation due to the lower res press and temperature gradients; ie less rate of heat loss."

Can you explain this for me? We want the Steam-to-Oil-Ratio (SOR) to be lower, correct? Less steam (less consumption of natural gas) for each barrel of oil produced. And less rate of heat loss would be better, because it would be more efficient. So when you say SOR's "increase" do you mean "become more optimal" rather than "become a higher number"?
