Abstract

A series of well-characterized laboratory experiments in a two-dimensional, cross-bedded beadpack were carried out. A two-phase three-component (isopropyl alcohol (IPA)/water/cyclohexene) liquid system, that exhibits an upper critical point at ambient conditions, was used as the fluid model. The produced oil and gas in the experiments were not to be in compositional equilibrium. This was observed both in homogeneous and heterogeneous packs. As a result the oil recoveries and gas cut predicted by compositional simulation for multi-contact miscible (MCM) displacements in laminated media differed significantly from the experimental results, although an excellent match was obtained for the first contact miscible (FCM) and immiscible displacements. Although the simulator was able to predict the saturation distributions, recovery curves, and gas cuts for the FCM and immiscible displacements in the cross-bedded model with great accuracy, it over-predicted equilibrium oil recovery by as much as 11% for the condensing drive and 12% for the vaporizing drive. This is an abstract of a paper presented at the SPE Europe/EAGE Annual Conference (Madrid, Spain 6/13-16/2005).
