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.

Results of the India National Gas Hydrate Program Expedition 02
The Government of India, with the support of the U.S. Geological Survey (USGS), has released the initial results of the most comprehensive gas hydrate scientific drilling investigation ever undertaken. Coinciding with the release of the Journal of Marine and Petroleum Geology Special Issue on Marine Gas Hydrate Reservoir Systems Along the Eastern Continental Margin of India: Results of the...Assessment of Gas Hydrate Resources in the North Slope of Alaska, 2018
The U.S. Geological Survey (USGS) has updated the previous 2008 assessment of undiscovered, technically recoverable gas hydrate resources beneath the North Slope of Alaska. This new 2018 assessment again indicates the existence of technically recoverable gas hydrate resources―that is, resources that can be discovered, developed, and produced using current technology. Using a geology-based...Alaska North Slope 2018 Hydrate 01 Stratigraphic Test Well
The National Energy Technology Laboratory (NETL), the Japan Oil, Gas and Metals National Corporation (JOGMEC), and the U.S. Geological Survey (USGS) are leading an effort to conduct an extended gas hydrate production test in northern Alaska.Gas Hydrates
Central Energy Resources Science Center - Gas Hydrates Project PageU.S. Geological Survey Gas Hydrates Project
The USGS Gas Hydrates Project has been making contributions to advance understanding of US and international gas hydrates science for at least three decades. The research group working on gas hydrates at the USGS is among the largest in the US and has expertise in all the major geoscience disciplines, as well as in the physics and chemistry of gas hydrates, the geotechnical properties of hydrate...Gas Hydrates- Climate and Hydrate Interactions
The USGS Gas Hydrates Project focuses on the study of natural gas hydrates in deepwater marine systems and permafrost areas. Breakdown of gas hydrates due to short- or long-term climate change may release methane to the ocean-atmosphere system. As a potent greenhouse gas, methane that reaches the atmosphere from degrading gas hydrate deposits could in turn exacerbate climate warming.Gas Hydrates- Energy
Natural gas production from methane hydrates may someday prove viable. The USGS Gas Hydrate Project takes part in US and international programs to investigate the potential of deepwater marine and permafrost gas hydrates as an energy resource. Long-term production tests are the next step in this research.Gas Hydrates - Primer
What is Gas Hydrate? Gas hydrate is an ice-like crystalline form of water and low molecular weight gas (e.g., methane, ethane, carbon dioxide). On Earth, gas hydrates occur naturally in some marine sediments and within and beneath permafrost. Gas hydrates have also been inferred on other planets or their moons.Marine Methane Hydrate Field Research Plan
In 2013, the U.S. Department of Energy’s (DOE) National Energy Technology Laboratory (NETL), in partnership with the Consortium for Ocean Leadership (COL), initiated a new field-focused methane hydrate research planning effort that would inform, and potentially lead to, future off shore drilling field expeditions. The primary objective of this project was to conduct planning that would help define...Successful Test of Gas Hydrate Production Test Well Ignik Sikumi on Alaska's North Slope
On May 2, 2012 the U.S. Department of Energy (DOE) announced the completion of the field testing phase of the Ignik Sikumi gas hydrate production test well project on the North Slope of Alaska. The USGS participated in many phases of this work, including originally identifying the test site, which was based on almost 30 years of USGS geologic studies on gas hydrates in northern Alaska.Korean National Gas Hydrate Program, Second Ulleung Basin Gas Hydrate Drilling Expedition
As a part of Korean National Gas Hydrate Program, the Second Ulleung Basin Gas Hydrate Drilling Expedition (UBGH2) was successfully performed by using the D/V Fugro Synergy to establish 13 research drill sites in the period of time from July 8 to September 30, 2010. The first leg of this expedition focused on logging-while-drilling operations, while the second leg focused on both conventional and... - Data
