The Motor Driven Core Barrel (MDCB) is a prototype coring system that uses mining industry diamond coring technology to obtain core in difficult formations. It is compatible with the APC/XCB coring systems. ODP/TAMU is currently developing core barrel extension rods for the MDCB. These rods will improve the efficiency of the MDCB by allowing multiple MDCB cores to be cut without having to ream down with the BHA between cores. The new rods should be ready for deployment this summer. Also, a spare downhole mud motor has been built, tested, and shipped to the JOIDES Resolution for Leg 167.
