摘要： Beschrieben wird die Verwendung von freien, aromatischen Säuren, die mindestens zwei aromatische Ringsysteme, oder mindestens zwei Säurefunktionalitäten enthalten, und/oder deren Salzen zur Beeinflussung von Gesteinsformationen bei der Ausbeutung unterirdischer Erdöl- und/oder Erdgaslagerstätten. Die freien Säuren kommen insbesondere bei der Beeinflussung und vor allem der Steuerung des Säurezuflusses in Gesteinsformationen beim sogenannten Acidizing-Verfahren zum Einsatz. Geeignete Salze der genannten aromatischen Säuren dienen der Verringerung der Gesteinspermeabilität und insbesondere der Verringerung des Wasserzuflusses. Neben dieser Verwendung werden auch entsprechende Verfahren beansprucht.
