Abstract
Certains modes de réalisation de cette invention ont trait à un liquide non polymère pouvant épaissir de manière réversible, ayant une faible viscosité dans un acide fort et se gélifiant lorsque la concentration d'acide n'est que peu réduite, puis qui est décomposé par l'acide. Cette invention porte, notamment, sur un mélange aqueux d'agents tensioactifs zwittérioniques, d'acides inorganiques et organiques. Elle concerne, plus précisément, l'usage qui est fait de ce liquide comme agent de dérivation pour grès endommagés, par exemple, avant une acidification de matrice.
