Abstract:
The instant disclosure is directed to a method of enhancing adsorption of a salt inhibitor onto a wellbore region, wherein the method comprises preconditioning the wellbore region, emplacing the salt inhibitor into the wellbore region, and shutting in the wellbore region for a period of time to at least initiate adsorption of the salt inhibitor onto the wellbore region. The salt inhibitor comprises an at least partially water soluble compound comprising a Group 3 to Group 15 metal and/or an at least partially water soluble compound having any one of the formulae: wherein X is O or S; and R1, R2, R3, R4, and when present, R5 and/or R6 each independently comprise an organic or an inorganic functional group.
