Influence of the geological and geochemical characteristics of heavy oils on their recovery | 1987 | oil buoyancy; heavy oils; Likouala oil field; Emeraude oil field; water washing; oil saturation; biodegradation | The 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... |

Oil shale and tar sands | 1976 | oil shale; tar sands; United States; alternative fuels; in situ processing; fractuing tests | To continue its growth or even its existence, the United States must find new energy supplies to replace the petroleum we are rapidly depleting. No fossil energy form can offer a long-range solution, but coal offers a mid-range solution. Unfortunately we're not geared to use it, and learning to appl... |
