Enhanced coring system

Chikyu uses many different kinds of coring systems to collect sediment and formation samples (core) from below the seafloor. These coring systems are designed for different sampling requirements for different formation types. Operational needs also help choose which systems are best for a given purpose.

As drilling depths increase, the development of longer-lasting drilling bits and coring systems, including coring systems that don’t require drill pipe rotation become more important.

CDEX is developing highly capable coring systems to increase the recovery of high-quality cores from a range of formations and sediments.
