1 Oceanic Gas Hydrate Research and Activities Review Dr. Mary C. Boatman Presented By

2 Gas Hydrates: Short term Long term What are they? Why are they important? What matters to MMS?

3 Gas Hydrate: Ice-like structure that traps gases Source: U.S. Geological Survey Methane, Carbon Dioxide, Ethane, Butane, Propane, Hydrogen Sulfide

4 Hydrate Structures Sources: U.S. Geological Survey and Texas A&M University Concentrates gas with a ratio of ~ 1:160 One cubic foot of gas hydrate contains 160 cubic feet of gas at standard temperature and pressure Type IType IIType H

5 Hydrate Formation Requires Five Ingredients: Water Pressure Temperature Nucleation Site Gas - CH 4, CO 2, C 2 H 6, H 2 S, etc.

9 Why the interest in Gas Hydrates? Safety: Hydrates plug flowlines Hydrates can be geohazards Resource: Methane Hydrates are a source of natural gas Environmental: Sensitive Communities use hydrates as food Methane Hydrates can contribute to global warming

10 Safety Hydrates can form in flowlines and on equipment Hydrates occur naturally in the sediment

23 Environmental Chemosynthetic Communities: Sensitive Biological Communities Associated with Methane Hydrates Found in Deepwater throughout Gulf of Mexico Global Warming

24 S. 330 and H.R Methane Hydrate Research and Development Act of 1999 To promote the research, identification, assessment, exploration, and development of methane hydrate resources, and for other purposes. Funding: $42.5 million over 5 years Lead Agency: Department of Energy Consultation:Department of the Interior Department of Defense

25 International Interest in Methane Hydrate Recovery India: $56 million program Japan: $50 million program Canada: MacKenzie Delta Permafrost with Japan United Kingdom, Brazil, and Norway Russia: Messoyakha gas field

26 Hydrate Research at other Agencies: Department of Energy: Methane Hydrates as a Resource Naval Research Laboratory: Acoustic Properties of Sediments National Science Foundation: Basic Research into Hydrate Properties United States Geological Survey: Gas Hydrates as a Geohazard Methane Hydrates as a Resource

27 MMS Involvement in Hydrate Research Technology Assessment & Research Program Chemosynthetic Communities Resource Evaluation - mapping of surface anomalies Participation on Committees and in Consortiums Center for Marine Resources and Environmental Technology (CMRET)

28 3-D Seismic view of Gulf of Mexico Sea Floor

29 3-D Seismic Surface Anomaly Map of Cooper Field

30 Close-up view of Surface Anomaly with Hydrate

31 Vertical view of one of the seismic lines

32 Whats important to MMS? Short Term: Safety: Technology and Geohazards Environmental: Protecting Sensitive Biological Communities Long Term: Methane Hydrate Extraction New Technology Identification and Valuation of Resource Environmental Impacts
