Gli agenti tensioattivi, o surfattanti, sono ampiamente utilizzati e trovano un gran numero di applicazioni nell’industria petrolifera. Ciò è dovuto alla loro notevole capacità di influenzare le proprietà delle superfici e delle interfacce. Recentemente, una delle applicazioni più importanti dei surfattanti è quella di efficaci inibitori di corrosione nell’industria petrolifera. Uno dei principali consumatori di inibitori di corrosione è l’industria petrolifera, dove vengono impiegati per ridurre il tasso di corrosione di diversi tipi di leghe di acciaio nelle attrezzature dei pozzi di gas e petrolio. In questo settore si riscontrano sia corrosione generale che localizzata. I demulsificanti sono una classe di tensioattivi utilizzati per destabilizzare le emulsioni. Questa destabilizzazione si ottiene riducendo la tensione interfacciale all’interfaccia dell’emulsione. La corrosione, insieme al carico meccanico ciclico, causa la fatica da corrosione che porta a un guasto prematuro della colonna di perforazione. Si tratta di una causa di estrema preoccupazione per chi opera nel settore della perforazione.
