A correlation of steam chamber size and temperature falloff in the early-period of the SAGD Process

摘要

Steam Assisted Gravity Drainage (SAGD) is a widely-used thermal oil recovery technique in western Alberta's oil sands reservoirs. Because of reservoir heterogeneity, the wellbore hydraulics and undulation, non-uniform steam chambers will evolve. Numerical simulation allows for the practical prediction of steam chamber size in SAGD. However, the long computation time in 3D scenarios and the impact of uncertainties in input parameters limit its application.
