Abstract
The present invention provides a method for protecting the integrity of a core sample during transport from a subterranean formation to the surface comprising: cutting a core sample from the subterranean formation using a drilling fluid; encapsulating the core sample with an encapsulating material separate from the drilling fluid, the encapsulating material being capable in the absence of a chemical reaction of protecting core sample integrity during transport from said subterranean formation to said surface; and, transporting the encapsulated core sample from the subterranean formation to the surface.
