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

摘要

A method of isolating a subterranean zone using 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. A conduit is placed in the well bore to allow the sealant composition to be pumped into the well bore. The sealant composition is pumped down through the conduit and up through an annulus disposed between the conduit and walls of the well bore. After the sealant composition has cured in the annulus, it isolates the interior of the conduit from the subterranean zone and attaches the conduit to the walls of the well bore. In an embodiment, the weight ratio of the polymerized furfuryl compound to the non-polymerized furfuryl compound in the sealant composition ranges from about 1:1 to about 10:1.
