DHT Workshop:

1
DHT Workshop Defining New Goals, Techniques,
and Development/Support Mechanisms for Downhole
Tools in the Integrated Ocean Drilling
Program (Flemings, Murray, Fisher)
2

• Downhole Tools ODP/DSDP
• ODP/DSDP - notable DHT achievements in broad
  range of environments
• The road to success rough in some cases
• Should DHT operation and development within IODP
  be fundamentally different from that practiced
  during DSDP and ODP?

3

• MOTIVATION
• New Program, New Platforms, New Funding
  Structure, New Management Structure
• Window of Opportunity to strengthen role of
  Downhole Tools in Ocean Drilling
• Science-Engineering interface is under-exploited
  potential for big science reward

4

• MOTIVATION IODP is different
• Simultaneous use of riser, riserless, and
  mission-specific platforms
• Exploration of environments/problems that
  couldnt addressed during DSDP and ODP.
• Influences planning, funding, at-sea operations,
  and technical development.

5

• IODP is Different
• 3 Partners Japan, U.S., Europe
• 3 Platforms (MSP, Riser, Riserless)
• Central Management Office-IMI

6

• New/better DHTs critical to IODP success
• DHTs are essential for addressing the three
  primary IODP research themes
• Support of engineering development of new
  measurement and sampling tools is one of the
  three guiding principles for the implementation
  of the IODP.

7

• Key Workshop Goals
• What downhole measurements and sampling are
  essential to address fundamental goals described
  in the ISP to the IODP?
• What capabilities currently exist for use on the
  various IODP platforms, and what technologies are
  needed for future success?
• How can IODP and the various scientific and
  technical partners nurture development of new
  tools, and facilitate the transfer of technology
  from the development stage to become part of
  standard operations?

8

• Workshop Focus Downhole Tools
• Autonomous DHTs are self-contained instruments
  that make in-situ measurements or collect samples
  over short depth intervals, in single sample or
  "burst" sampling mode.
• Excludes wireline/LWD logging
• Allows focus on DHTs, -- no primary IODP
  contractor.
• Excludes long term CORK monitoring
• Topical restriction focuses discussion to
  address pressing issues
