Abstract

This paper presents the results from six gravity stable gas injection experiments in 1.2 m long water flooded sandstone cores. All experiments were performed close to ambient conditions with different combinations of spreading and wetting characteristics for time periods of 50 to 170 days. The effectiveness of oil recovery by gravity drainage for the different flow conditions are shown. A mixed wet membrane was placed on the outlet of each core to eliminate end effects. Experimental techniques for eliminadon of capillary end effects are discussed. Saturation profiles in the cores were determined at the end of each experiment.
