1. A process comprisinginjecting an initial charge of a mixture, the mixture being formed from at least a water-insoluble adsorbent and at least one well treatment agent, into a well bore formed in a subterraneous formation so as to form a downhole matrix within the formation;

  • injecting a solution comprised of an additional amount of the well treatment agent into the formation after the initial charge of the at least one well treatment agent has been substantially depleted; and

    thenpressurizing the well bore for a time and under conditions sufficient to reactivate the down-hole matrix in the formation, so that the treatment agent activity of the matrix is increased relative to the treatment agent activity of the matrix just prior to injecting the solution.
