A process for closing pores in a bottom water zone where steam is directed so as to by-pass a zone of the formation containing hydrocarbonaceous fluids. Once a portion of the bottom water zone has reached a temperature in excess of about 300°F, steam entry is ceased. Afterwards, a temperature activated gellable composition is placed into the bottom water zone. When the composition reaches that portion of the bottom water zone where a temperature in excess of about 300°F has been reached, the composition activates and forms a rigid gel. Thereafter, a steam flooding method is commenced. Steam is diverted from the bottom water zone and into an upper zone containing hydrocarbonaceous fluids.
Méthode pour obturer les pores dans la zone d'eau de fond, consistant à diriger la vapeur en lui faisant éviter la zone de la formation renfermant des fluides hydrocarbonés. Dès qu'une partie de la zone d'eau de fond a atteint une température dépassant environ 300 °F, on arrête d'envoyer la vapeur. Par la suite, une composition gélifiable activée par la température est introduite dans la zone d'eau de fond. Lorsque la composition atteint la partie de la zone où la température dépasse environ 300 °F, ladite composition agit et forme un gel rigide. On commence ensuite l'injection de vapeur. La vapeur est déviée de la zone d'eau de fond vers une zone supérieure renfermant des fluides hydrocarbonés.
