... Drainage (SAGD) is one of the most popular thermal oil recovery techniques in heavy oil reservoirs. In a typical SAGD operation, a horizontal well pair consisting of one injection well and one production well is drilled in an unconsolidated oil sand reservoir. In this operation, high-pressure and high...
