Method for in-situ heated annulus refining process |
摘要 |
Recovery of viscous petroleum such as from tar sands is assisted using a controlled flow of hot fluid and hydrogen-generating gas in a flow path within the formation; thus a solid-wall hollow tubular member in the formation is used for conducting hot fluid to promote hydrogenation in conjunction with a hydrogen-generating gas and reduce viscosity of the petroleum to develop a potential passage in the formation outside the tubular member into which a drive fluid is injected to promote movement of the petroleum to a production position.
