ABSTRACT:
The present invention provides a method for restricting a fluid flow path in subterranean geological formations to facilitate the removal of hydrocarbons from the subterranean geological formation during enhanced oil recovery techniques. The method includes the steps of injecting a first water volume into the fluid flow path thereby displacing fluids present in the fluid flow path. The next step is injecting an alkaline volume into the fluid flow path thereby displacing the first water volume ahead of the alkaline volume. The injections create a first water and alkaline mixed continuum between the first water volume and the hydroxide volume wherein the relative concentrations of water and hydroxide vary along a length of the first water and hydroxide mixed continuum wherein the relative concentrations of water and alkaline are conducive to the formation of scale upon the surfaces of the subterranean geological formation.
