Methods for recovering heavy oil are provided. In at least one embodiment, the process includes conditioning a reservoir of interest, then initially producing fluids and particulate solids such as sand to increase reservoir access ("slurry produc-tion"). The initial production may generate high permeability channels or wormholes in the formation, which may be used for heavy oil production processes ("hydrocarbon production") such as cold flow (CHOPS) or enhanced production processes such as SAGD, or VAPEX.

L'invention concerne des procédés pour récupérer des huiles lourdes. Dans au moins un mode de réalisation, le procédé comprend le conditionnement d'un réservoir concerné, puis la production initiale de fluides et de solides particulaires tels que du sable pour augmenter l'accès au réservoir ("production de boue"). La production initiale peut produire des canaux ou des trous de vers dans la formation, qui peuvent être utilisés pour des traitements de production d'huile lourde ("production d'hydrocarbures") tels que des procédés à écoulement froid (CHOPS) ou de production améliorée tels que SAGD ou VAPEX.
