Abstract
021 LABORATORY AND NUMERICAL STUDIES OF FIRST CONTACT MISCIBLE WAG DISPLACEMENT: THE EFFECTS OF WAG RATIO AND FLOW RATE ABSTRACT 1 Miscible WAG injection has been implemented successfully in a number of fields around the world and there are a number of numerical studies investigating the effect of rate gravity slug size heterogeneity on WAG performance. However there are very few laboratory studies of WAG displacement efficiency reported in the literature. In this paper we report the results from a series of well-characterised experiments using glass beadpacks. The aim of these experiments is • to investigate the impact of first
