ABSTRACT:
The present invention provides a method for maximizing the chemical integrity and, if desired, maintaining the mechanical integrity of a core sample during transport from a subterranean formation to the surface. The method involves cutting and encapsulating the core sample as it enters the core barrel with an encapsulating material that either (a) inherently is capable of protecting the chemical integrity of the core sample, or (b) is capable of increasing in viscosity and/or solidifying in response to natural decreases in temperature to maintain the mechanical integrity and maximize the chemical integrity of the core sample during transport.
