Sealant compositions and methods of using the same to isolate a subterranean zone from a disposal well

A method of isolating a subterranean zone, comprising:

• forming a sealant composition comprising a partially polymerized furfuryl compound selected from the group consisting of furfuryl alcohol, furfuryl aldehyde, and combinations thereof;
• and
• pumping the sealant composition into a well bore positioned adjacent to the subterranean zone;
• further comprising drilling the well bore and placing a conduit in the well bore prior to said pumping the sealant composition, wherein the sealant composition is pumped down through the conduit and up through an annulus disposed between the conduit and walls of the well bore;
• and
• further comprising allowing the sealant composition to cure in the annulus, thereby isolating the subterranean zone and attaching the conduit to the walls of the well bore, wherein the partially polymerized furfuryl compound exhibits a cure time of from about 6 to about 96 hours in the well bore.
