25 Influence of the geological and geochemical characteristics of heavy oils on their recovery1987oil buoyancy; heavy oils; Likouala oil field; Emeraude oil field; water washing; oil saturation; biodegradationThe migration of an oil into a trap is governed by its buoyancy, the capillary pressure, and the hydrodynamic forces. For heavy oils the buoyancy is low; therefore, they can only saturate high-permeability zones, which are also preferentially swept by steam in a steam-drive recovery operation. Howev...
