Abstract
The invention relates to a process making it possible to consolidate a geological formation without significantly reducing its permeabiity. A liquid mixture (5) is injected into the formation (1) traversed by a well (2) and then at least one gas is injected through the formation under appropriate conditions. More specifically, the liquid mixture contains a polymerizable substance, preferably a melamine-formaldehyde resin, and at least one catalyst having a Lewis acid character and it substantially polymerizes at the temperature and pressure of the formation, while bonding the unconsolidated elements. Application to the consolidation of a geological formation containing sand.
