Abstract

Viene descritta una composizione acquosa gelificabile avente tempo di gelificazione ritardato, contenente un polimero idrosolubile reticolabile con Cr 3+ ed un sistema reticolante/ritardante contenente uno ione Cr 3+ e un legante acido salicilico, dove detto legante può essere in forma libera oppure in forma complessata con lo ione Cr 3+, oppure parzialmente in forma libera e parzialmente in forma complessata.Una tale composizione è utile per modificare la permeabilità in giacimenti petroliferi in un ampio intervallo di temperature, da circa 60°C a 120°C o più.
