摘要
The invention relates to a method making it possible to consolidate a geological formation, without appreciably reducing its permeability. A liquid mixture (5) is injected into the formation (1), through which a well (2) passes, and then at least one gas is injected through the formation under suitable conditions. More specifically, the liquid mixture contains a polymerizable substance, preferably a melamine-formaldehyde resin, and at least one catalyst of the Lewis-acid type, and it polymerizes substantially at the temperature and pressure of the formation, thereby binding the unconsolidated elements. The invention is used for consolidating a geological formation containing sand. IMAGE
