Patent

CA 2662807

A method for obtaining heavy oil is disclosed. The method includes mixing a material including heavy oil (e.g., oil sand) with a solvent including biodiesel to form a mixture and separating the mixture into a oil-enriched solvent phase and a residual sand phase. The method also can include introducing a solvent including biodiesel into an in-situ geological formation including heavy oil and collecting a mixture including biodiesel and heavy oil from the formation. For example, the mixture can be collected after the solvent travels through at least a portion of the formation by gravity. A method for producing biodiesel also is disclosed. The method includes microbially digesting asphaltenes to form a liquor including a fatty acid and reacting the fatty acid with an alcohol to produce biodiesel. This method can be used to convert petroleum asphaltenes and/or coal asphaltenes into biodiesel.

La présente invention concerne un procédé de production d'huiles lourdes. Le procédé consiste à mélanger une substance contenant des huiles lourdes (des sables bitumineux, par exemple) avec un solvant renfermant un biocarburant sous la forme d'un mélange et séparer le mélange en une phase de solvant enrichi en huile et une phase de sables résiduels. Le procédé peut également consister à introduire un solvant contenant un biocarburant dans une formation géologique in situ renfermant des huiles lourdes et recueillir un mélange composé du biocarburant et des huiles lourdes provenant de la formation. Le mélange peut, par exemple, être recueilli lorsque le solvant a traversé une partie au moins de la formation sous l'effet de la gravité. L'invention a trait en outre à un procédé de production de biocarburant. Le procédé consiste à effectuer une digestion microbienne des asphaltènes afin d'obtenir une liqueur contenant un acide gras et faire réagir l'acide gras avec un alcool pour produire le biocarburant. Ce procédé peut servir à convertir des asphaltènes provenant du pétrole et/ou des asphaltènes provenant du charbon en biocarburant.
