Timothy S Collett
Dr. Collett provides science leadership and management oversight within the Energy Resources Program (ERP) funded tasks in the USGS Gas Hydrate Project, which include the (1) North Slope of Alaska Gas Hydrate Energy Production Research Task, (2) Gas Hydrate Energy Assessment Task, (3) International Gas Hydrate Research and Science Advisor Task, and the (4) Gulf of Mexico Gas Hydrate Task.
Dr. Collett has been a research geologist in the U.S. Geological Survey (USGS) since 1983. Tim received a B.S. in geology from Michigan State University, a M.S. in geology from the University of Alaska, and a Ph.D. in geology from the Colorado School of Mines. Tim is the Project Chief of the Energy Resources Program funded gas hydrate research efforts in the USGS. He has received the Department of the Interior Meritorious Service Award and the Golomb-Chilinger Medal from the Russian Academy of Natural Sciences and the Natural Resources of Canada Public Service Award. Tim has been the Chief and Co-Chief Scientist of numerous domestic and international gas hydrate scientific and industrial drilling expeditions and programs. He has been the Co-Chief Scientists and Operational Manager for the India NGHP Expedition 01 and 02 gas hydrate drilling and testing projects. Tim was a Co-Chief Scientist of the international cooperative gas hydrate research project that was responsible for drilling dedicated gas hydrate production research wells in the Mackenzie Delta of Canada under the Mallik 1998 and 2002 efforts. Tim was the logging scientist on the Gulf of Mexico JIP Gas Hydrate Research Expedition in 2005 and is the Co-Chief Scientist of the Integrated Ocean Drilling Program (IODP) Expedition 311, and the Gulf of Mexico JIP Leg II drilling project in 2009. He sailed as a science advisor on the Korean UBGH2 Expedition in 2010 and the 2017 University of Texas Gulf of Mexico 2-1 Hydrate Pressure Coring Expedition. Tim was also the Principal Investigator responsible for organizing and conducting the 1995 and 2008 USGS National Oil and Gas Assessment of natural gas hydrates. Tim is an Adjunct Professor in the Department of Geophysics at the Colorado School of Mines. Tim’s current research efforts in the USGS deal mostly with domestic and international gas hydrate energy resource characterization studies. His ongoing gas hydrate assessment activities in Alaska are focused on assessing the energy resource potential of gas hydrates on the North Slope. Tim’s international gas hydrate activities include cooperative projects with research partners in India, Korea, Japan, China, and Canada. Tim also continues to represent the USGS gas hydrate interest in the Gulf of Mexico through a U.S. Department of Energy cooperative. Tim has published more than 250 research papers along with 10 books and treatises on gas hydrates and other unconventional resources.

Future of gas hydrate research
Methane hydrates are ice‐like inclusion compounds, in which every volume of hydrate can contain as much as 180 volumes (STP) of gas.The amount of methane in natural gas hydrates is twice the total recoverable fossil fuel reserve. Because of their natural abundance in oceans and permafrost, hydrates have become an exciting national and international research issue. The movement of the gas and oil i
