ABSTRACT
One of the novel technologies to produce bitumen from oil sands is the injection of steam into the reservoir. The injected steam contacts the oil sand, heats, mobilizes and pushes the bitumen out of the reservoir. The stability of the water–bitumen interface is a crucial factor in the steam injection method. The shape, strength and energy of this interface are expected to play important roles in the recovery of bitumen from oil sands. However, measurements on bitumen-water interfaces are not apparent in the literature. A measurement of relevance would be the contact angle of water and bitumen at different temperatures. In this paper, the results of contact angle measurements of water and bitumen are presented. The measurements cover a temperature range from ambient to the saturation temperature for a given pressure. The experiments are run in X-ray transparent cells and the contact angles are measured through images taken in a micro-CT scanner.
