Rainbow Keg River B池EOR方案要求在池顶部区域放置12%（再循环后的净含量）的原始HCPV混相库。这一排将垂直向下输送超过1 PV的干气。随着先前注入的水被采出，注入的溶剂和追踪气体将向下推动油/水接触面（OWC）。在以前被水占据的区域将形成第三期油库。本文报告了第三次洪水的表现，1987年水库模拟研究的结果，以及在监测洪水时遇到的问题和业务策略。实施的完井技术操作洪水进行了说明，并审查了方案的经济性。
The Rainbow Keg River B pool EOR scheme calls for placement of a 12% (net after recycle)-original-HCPV miscible bank in the crestal region of the pool. This bank will be chased vertically downward with more than 1 PV of dry gas. The injected solvent and chase gas will push the oil/water contact (OWC) downward as the previously injected water is produced. A tertiary oil bank will be formed in the region previously occupied by the water. This paper reports tertiary flood performance, results of the 1987 reservoir simulation study, and the operational strategy and problems encountered in monitoring the flood. The well-completion technique implemented to operate the flood is described, and the scheme economics is reviewed.
