Traditional coring methods do not record any in situ geophysical measurements while coring. Adding bottom hole environmental conditions (e.g. temperature, pressure) and drilling parameters (e.g. bit RPM, BHA inclination), as well as geophysical measurements (e.g. gamma radiation) to the core as it is being cut will dramatically increase the accuracy and usefulness of scientific measurements using core samples. These data are invaluable for improving drilling and coring safety with reference to specific sediments or rock types. This technology is currently being developed for use aboard Chikyu.
- Develop a measuring and recording system for simultaneous downhole core cutting and data logging.
- Develop sensors and data loggers for high temperature (~350˚C) and high pressure (~150 MPa) environments.
