D/V CHIKYU: RISER OPERATIONS AND THE FUTURE OF SCIENTIFIC OCEAN DRILLING

摘要

The addition of riser capability to the scientific drilling toolbox will enhance the ability to drill to greater depths with better recovery, produce more stable, long-lived boreholes suitable for reentry and long-term monitoring operations, and allow drilling, coring, and monitoring in an array of geological environments that were previously inaccessible to the scientific drilling community. The ability to monitor and sample mud-gas, fluids, and cuttings adds another layer of analytical and data collection capabilities and will help to enhance our ability to integrate drilling information, core-derived data, and logging data, and may enhance the ability to integrate these data with geophysical analyses.
