1. A method of drilling a well comprising during said drilling of the well a stabilization treatment of an underground formation surrounding a borehole, wherein said stabilization treatment comprises placing a treatment fluid in the formation, wherein the treatment fluid comprises a cross-linkable polymer and a cross-linking agent, allowing the treatment fluid to gel in-situ, and pumping, after placement of the treatment fluid in the formation, an activator fluid into the well to accelerate the crosslinking of the polymer and the development of the gel strength.
