For best results, core orientation technique(s) should be selected on the basis of the operating conditions and the ultimate applications of the results.

Proper [[core handling]] can enhance orientation quality regardless of the techniques selected<ref name=pt03r37 /><ref name=pt03r11 />) (also see the chapter on “[[Core handling]]” in Part 3. A primary goal of handling procedures is to reconstruct the core as accurately and completely as possible immediately after recovery from the barrel. It is recommended that an asymmetric scribe shoe be used on all core runs to aid reconstruction.

At the well site, cores should be carefully fitted together into ''continuous intervals'', which are defined as lengths of core in which each piece fits into the next. Continuous intervals can vary in length from a few centimeters to [[length::10 m]] or more. Intervals are nomally broken by drill string connection points, core rubble zones, core spinoffs, and the tops and bottoms of core runs.
