Abstract
Un procédé de démarrage pour une opération de drainage par gravité au moyen de vapeur (DGMV) peut comprendre des impulsions de pression depuis lintérieur dune section horizontale dun ou des deux puits DGMV, la source dimpulsion étant dans un fluide de démarrage de manière que les impulsions de pression se propagent dans une zone de traitement de la région entre les puits DGMV, assurant ainsi une microfracturation ou une dilatation dans la zone de traitement. Le processus peut également comprendre la fourniture dune pression de pénétration sur le fluide de démarrage de manière quune partie du fluide de démarrage pénètre dans la zone de traitement pour augmenter la mobilité du fluide. Le processus peut être mis en uvre dans des réservoirs peu profonds, des réservoirs en plastique et des opérations ayant une limite de pression de fonctionnement maximale basse, par exemple.
