A B S T R A C T METHOD OF PLACING AND CONSOLIDATING A MASS OF PARTICULATE MATERIAL AND COMPOSITION FOR USE IN CARRYING OUT SAID METHOD Said grains coated with a solid non-cured epoxy resin with a softening point above 35°C are placed in a well for gravel pack, well repair or fracturing purposes. The epoxy resin softens at formation temperature and reacts with a hardener (such as a tertiary amine) diluted in water present in the pore space of the mass of sand grains. A consolidated mass of sand grains is thus obtained. The coated sand grains can be transported to the well site and stored over long periods at relatively high temperatures without risk of quality decrease.
