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 injected oxidizing gas to produce a solid compound which consolidates the formations without substantially reducing their permeability. The process is characterized by the combined use of a polyethylenic hydrocarbon and of a catalyst which comprises at least one element of the group consisting of zirconium, cerium, lanthanum and lanthanides and at least one element selected from the group formed by vanadium, manganese, cobalt and zinc.
