Coring Tools & Hardware

Coring and Measurement Tools

• Advanced Piston Corer (APC): used in soft ooze and sediments
• Rotary Core Barrel (RCB): used in medium to hard crystalline sediments
• Extended Core Barrel (XCB): used in firm sediments
• Advanced Piston Corer Temperature (APCT-3): used to obtain formation temperatures to determine the heat flow gradient
• Sediment Temperature (SET): designed to take temperature measurements in soft sediment

Reentry Hardware

• Free Fall Funnel (FFF): used to reenter a hole
• Reentry Cone and Casing (RECC): used as a permanent seafloor installation (or legacy hole) able to support nested casing strings
  • For more information regarding sites with reentry cones, contact Kevin Grigar.

Monitoring Instruments

• Vibration Isolated Television Frame (VIT)
• Rig Instrumentation System (RIS): data acquisition system with the ability to present real-time data and drilling parameters in digital and graphical formats

Wireline Tools

• Lockable Float Valve (LFV): allows a return to coring following logging
• Mechanical Bit Release (MBR): designed to remotely release the RCB core bit from the BHA to allow logging tools to pass through

Tools Available on Request

Due to budgetary and manpower constraints, the following tools may be made available, but must be specifically requested well in advance of an expedition. For more information, contact Kevin Grigar.

• 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
• Sediment Temperature Pressure (SETP): designed to take temperature and pressure measurements in soft sediments
• Water Sampling Temperature Probe (WSTP): takes column water samples in the hole
