Evaluation of Oil and Exploitable Oil Volume in Place by SAGD Technology

Abstract

Abundant oil sand resource has been explored in Albert basin of Canada and SAGD is a mature and widespread oil sand development technology. Oil sand exploitable oil volume in place evaluation is of vital importance for the development of oil sand. Thickness of continuous oil sand reservoir, effective length and reservoir to gross ratio of horizontal well pairs, oil and water distribution have significant impact on the oil sand production from the dynamic analysis. Evaluation of oil sand resource and exploitable oil volume in place is carried out through analyzing of the geological parameters that affect steam chamber growth and well deployment requirements. Balancing structure, reservoir distribution and well pair deployment requirements when evaluating the exploitable bitumen volume to achieve the optimization of oil sand production and maximum utilization of oil sand resource.
