...) is developed by combining Butler's ( Butler et al., 1981 , 1985 ) oil drainage analytical expression for SAGD and VAPEX ( Gupta el., 2010 ) solvent dilution effects. This approach, with some modifications, is validated by the use of a 2D simulation. Numerical simulation of a short length-scale process like...

... to make the process economic. Recent experiments show that oil flow is coupled to water flow during three-phase gravity drainage in water-wet system. In this paper, we argue that this type of flow coupling can be significant during SAGD. We extend Butler (1987) analytic model for the rise...

... The concept of SAGD, initially proposed by Butler and his colleagues ( Butler et al.,1981 ; Butler and Stephens, 1981 ), places two horizontal wells close to the bottom of a formation. The injection well is above the producer a short vertical distance (4-10 m). Steam is injected continuously...

An analytical model developed by Butler and Mokrys 1 showed that the oil rate should be proportional to the square root of reservoir transmissibility.
