ABSTRACT:
This process comprises injecting into the formations a liquid organic mixture containing at least one polymerizable chemical compound and a catalyst. The organic mixture reacts with a limited amount of a injected oxidizing gas to give a solid product which consolidates the formations without substantially reducing their permeability. The catalyst is characterized by the combination of lead and of at least an element of the group constituted by nickel, copper and zinc.
