ABSTRACT:
An oxygenated foam is injected into a loosely consolidated, clay-containing sandstone formation surrounding a well penetrating a hydrocarbon-bearing reservoir. Combustion is initiated between the oxygenated foam and hydrocarbons within the reservoir to burn the formation and form said consolidated zone around the well that acts as a barrier to the passage of sand into the well along with produced hydrocarbons.
