Coring Tools & Hardware

JOIDES Resolution

Technical Note 31: Overview of Ocean Drilling Program Engineering Tools and Hardware
Active Heave Compensator (AHC): used to reduce the effect of vertical ship heave on the drill string and coring tools
Bottom-Hole Assembly (BHA)
Vibration Isolated Television Frame (VIT)
Rig Instrumentation System and Load Pins (RIS): data acquisition system with the ability to present real-time data and drilling parameters in digital and graphical formats

Advanced Piston Corer (APC): used in soft ooze and sediments
Rotary Core Barrel (RCB): used in medium to hard crystalline sediments
- Sonic Core Monitor (SCM)
Extended Core Barrel (XCB): used in firm sediments
Advanced Diamond Core Barrel (ADCB): used in hard sedimentary or igneous formations
Motor Driven Core Barrel (MDCB): Used in interbedded materials and hard fractured rock
Pressure Core Sampler (PCS): used in sediments while maintaining in situ pressure
Core Bits

Drill-In-Casing (DIC) System: used to drill in a short casing string simultaneously with the bit to support an unstable sediment zone
Free Fall Funnel (FFF): used to reenter a hole
Hard Rock Base (HRB): Used to focus the direction of the drill bit into hard irregular seafloor surfaces
Hard Rock Reentry System (HRRS): used to install casing with reentry capability on a sloping or rough hard rock seafloor
Reentry Cone and Casing (RECC): used as a permanent seafloor installation (or legacy hole) able to support nested casing strings
- Database query of sites with reentry cones
Underreamers, Bi-Center Reamers, and Mud Motors

Downhole Logging Tools
Advanced Piston Corer Temperature (APCT): used to obtain formation temperatures to determine the heat flow gradient
Davis-Villinger Temperature Probe (DVTP): used to take heat-flow measurements in semiconsolidated sediments that are too stiff for the APCT
Sediment Temperature Tool (SET): has replaced the DVTP
Water Sampling Temperature Probe (WSTP)
Instrumented Water Sampler (IWS): formation fluid sampling tool
Drilling Sensor Sub (DSS): used to record drilling parameters (weight on bit, torque on bit, etc.)

Conical Side Entry Sub (CSES)
Lockable Float Valve (LFV)
Hard Rock Orientation (HRO)
Mechanical Bit Release (MBR): designed to remotely release the RCB core bit from the BHA to allow logging tools to pass through
