Steamflooding Wabasca tar sand through the bottomwater zone--scaled model tests

Steamflooding a tar sand with a communicating bottomwater zone was investigated in a three-dimensional, scaled, laboratory model. Scaling is discussed and equipment and procedures are described. The authors studied the process mechanisms and the influence of steam rate and initial oil saturation, and compared performance of single and multiple patterns. The bottom water was found to counteract gravity segregation of the steam. If the steam rate is high enough, no gravity override occurs, and much of the formation is swept layer by layer, resulting in high recovery of oil. But oil/steam ratios are rather low, particularly at low initial oil saturation and in the single pattern pilot where oil bypasses the production wells.
