A system for treating a subsurface hydrocarbon containing formation is disclosed. The system includes one or more tunnels. The tunnels have an average diameter of at least 1 m. At least one tunnel is connected to the surface. Two or more wellbores extend from at least one of the tunnels into at least a portion of the subsurface hydrocarbon containing formation. At least two of the wellbores contain elongated heat sources configured to heat at least a portion of the subsurface hydrocarbon containing formation such that at least some hydrocarbons are mobilized.
La présente invention concerne un système pour le traitement dune formation souterraine contenant des hydrocarbures. Le système comporte un ou des tunnels. Les tunnels ont un diamètre moyen égal ou supérieur à 1 m. Au moins un tunnel est relié à la surface. Au moins deux trous de forage sétendent depuis au moins un des tunnels pour pénétrer dans au moins une partie de la formation souterraine contenant des hydrocarbures. Au moins deux parmi les trous de forage contiennent des sources de chaleur de forme allongée configurées pour réchauffer au moins une partie de la formation souterraine contenant des hydrocarbures de sorte quau moins certains hydrocarbures soient mobilisés.
