Abstract:
The present invention relates to a process for the treatment of the area (10) surrounding a well (1) in which an aqueous gelling solution comprising an alkaline potassium silicate solution and an acetic acid is prepared and then injected into a subterranean formation. This aqueous gelling solution makes it possible, by virtue of these gelling properties, to block the area (10) surrounding the well (1).
