13 Future Unconventional Energy Resource: Methane Hydrate

14 What is gas hydrate? Frozen methane molecules formed under high pressure & low temperature Where is gas hydrate located? Shallow subsurface of many of the world s oceans How much is there? How much is there? Possibly over 1 million TCF

15 Aggressive international Gas Hydrate drilling programs with promising preliminary results: India Multi-hole drilling program in 2006 with success in several basins Japan Drilling success in the Nankai Trough (est. 40 trillion cubic feet) Production target by year 2016 (wd = 700 m to 2,000 m) South Korea Several discoveries in the East Sea (wd = 1800 m) Commercial production by 2015 Also active: China, Vietnam

16 Long-term U.S. goals set forth in response to: Methane Hydrate Research and Development Act of 2000 Energy Policy Act of 2005 Domestically, stated goals are: Year 2015 arctic demonstrate technical recoverability Y 2025 i d Year 2025 marine demonstrate technical recoverability

17 MMS Related Activities MMS resource assessment In-place hydrate assessment release soon GOM only; remainder of OCS is in work Future: develop methodology for Technically Recoverable model Joint Industry Project (JIP) GOM drilling program scheduled Summer 2008 Targets = seismically i defined d hydrate prospects in sandy reservoirs At least three sites in DW GOM will be explored Chemosynthetic cruises June / July 2007 research cruise in the GOM ROV deployment to active methane vent sites on seafloor Investigate biological communities, hydrate accumulations, etc.

19 Conclusions -- Over 100 Billion BOE of Undiscovered Technically Recoverable Resources remain to be discovered in areas currently available for leasing on the OCS -- The GOM Lower Tertiary trend will continue to provide many exciting opportunities for the maritime energy transportation industry as more FPSO development scenarios are realized. -- As the demand for new sources of energy gy grows, so will the need to open access to additional OCS areas.

20 Conclusions -- Methane Hydrates exist in abundant quantities on the OCS but much research and development remains before this resource is considered economically recoverable offshore. -- Estimates of ECS potential for the U.S. exceed 1 million square kilometers, with nearly one half of that area lying within the Arctic. Hydrocarbon potential is estimated to be approximately 10 billion barrels of oil (USGS). Thank You.
