Resin composite with overloaded solids for well sealing applications
In one embodiment, a method of formulating a sealant to span an opening and form a seal with surfaces across the opening is provided. The method further includes selecting a fluid material capable of contacting and adhering to the surface of the opening and which reacts to form a solid material as a result of a thermal reaction. The method further includes selecting and intermixing one or more solids with the fluid material to form a composite, wherein the solids migrate within a column of the composite sealant before the composite sealant cures from a fluid to a solid and bonds to the surfaces of the opening, and the change in volume of the lower portion of the composite sealant into which the solids have migrated, as the temperature thereof changes during curing, is insufficient to cause it to pull away from the surfaces of the opening or fail internally.
