Process for consolidating geological formations

摘要

This process comprises injecting into the formations a liquid organic mixture containing at least a polymerizable chemical compound and a catalyst. The organic mixture reacts with a limited amount of an 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 at least one element of the group constituted by barium, zirconium, cerium, and lanthanides (e.g. lanthanum) and at least one element selected from the group formed by vanadium, manganese, iron, cobalt and zinc.
