Abstract | A process for preventing steam entry into a bottom water zone of a formation. Performations are made in a well which perforations communicate with the lowest level of said bottom water zone. Air is injected into the lowest level of said zone via said well which initiates low temperature oxidation thereby increasing the viscosity of said oil and making a heavy oil. When a desired viscosity is obtained, air injection is ceased. Said well is recompleted and perforations are placed in said well which causes it to communicate with a higher level oil saturated zone. Steam is injected into said higher level since the lowest level of the bottom water zone is closed because of the high viscosity oxidized oil. Thus, steam injection causes oil to be removed from the higher level of said formation. |
