Abstract

Selon l'invention, une technique facilite la production améliorée de fluide hydrocarboné. Un puits est formé dans une région souterraine par forage d'un trou de forage, par exemple un puits de forage, qui a une section latérale. La section latérale peut être située au moins en partie dans une zone non productive de la région souterraine. En coopération avec la section latérale, il est formé au moins un tunnel qui coupe la section latérale et pénètre dans une zone productive contenant du fluide hydrocarboné. Une pluralité de tunnels peut être formée pour s'étendre à partir de la section latérale vers l'extérieur dans la zone productive. Une opération de stimulation de puits, par exemple une fracturation hydraulique, est effectuée par le ou les tunnels pour stimuler une ou des zones de stimulation souhaitées à l'intérieur de la zone productive.
