Abstract
Les formations de grès pour le pétrole et le gaz naturel et les puits géothermiques sont efficacement stimulées lorsqu'une solution tampon d'acidification avec HF pour le grès est utilisée sans qu'une solution de bouchon de tête contenant de l'acide n'ait d'abord été introduite. Sans l'utilisation d'une solution de bouchon de tête, les solutions tampons d'acidification avec HF pour le grès dissolvent et enlèvent très efficacement les matériaux siliceux et, en même temps, réduisent au minimum la formation de fluorure de calcium.
