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. | 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.
