A method of stabilizing the well bore of a well penetrating a subterranean formation, comprising: drilling the wellbore with an aqueous based drilling fluid including an aqueous phase and a shale hydration inhibitor, wherein the shale hydration inhibitor is a polyether amine compound, and circulating into the wellbore. A fluid system for stabilizing the well bore of a well penetrating a subterranean formation, the fluid system comprising: a first fluid including an aqueous phase and a shale hydration inhibitor, wherein the shale hydration inhibitor is a polyether amine compound, and a second fluid including a dialdehyde crosslinking agent, wherein the combination of the first and the second fluids results in the formation of a polymer between the polyether amine compound and the dialdehyde crosslinking agent. An agent for the consolidation of a subterranean well bore, wherein the agent is the reaction product of a polyether amine compound with a dialdehyde crosslinking agent. |
