Sections of the core are taken for further analyses which may be full diameter samples or plug samples.
The core barrel can be cut and upto 30 cm of full diameter core can be taken up for preservation. The ends are sealed and dipped in hotmelt wax.
Exposed sections of the core can be preserved by wrapping the core in Saran Wrap and with a few layers of thick aluminum foil and then immersed in hot melt wax. The wax is allowed to dry and a few layers of wax are coated on the aluminum foil.
