Bill Waite (he/him/his), has spent his career being thrilled, confused, inspired and exasperated by gas hydrates, an educational relationship he began as a Stanford post-doc before shifting to the USGS in 1999. He has moved from laboratory studies of physical properties of pure gas hydrates, to laboratory and field measurements of the physical properties of gas hydrate in sediment.
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.
Research Interest
Gas hydrates are crystalline compounds formed when light “guest” molecules (such as methane) stabilizes cage-like structures in which water molecules enclose individual guest molecules. Gas hydrates are stable at reduced temperatures and elevated pressures that can be found on Earth in a variety of environments (primarily in marine continental slope sediment, and in sediments associated with permafrost). Their global distribution has helped create an international, multidisciplinary research community studying gas hydrate systems from biological, chemical, geological and geophysical perspectives. A wonderful consequence of the international interest has been in providing a rich, collaborative research experience that has significantly shaped and advanced my understanding of gas hydrate over the years.
Thanks to the U.S. Geological Survey’s long-term commitment to gas hydrate research , I have been able to spend 20+ years growing from my initial interest in pure gas hydrate physical properties to laboratory studies of gas hydrate in sediment, and now to ongoing field-based studies of naturally-occurring gas hydrate collected in pressure cores. Most of the USGS gas hydrate fieldwork I have been, and continue to be associated with, is focused on gas hydrate as an energy resource (additional information on those projects are accessible through the USGS Energy Program’s gas hydrate page.
I look forward to opportunities for connecting physical property investigations with interdisciplinary studies of microbiology and geochemistry as we continue to advance our natural-systems level appreciation of gas hydrate’s role not just as a potential energy resource, but as a dynamic element in natural processes.

Diatom influence on the production characteristics of hydrate-bearing sediments: Examples from Ulleung Basin, offshore South Korea
The Ulleung Basin Gas Hydrate field expeditions in 2007 (UBGH1) and 2010 (UBGH2) sought to assess the Basin's gas hydrate resource potential.

Gas hydrate is an ice-like form of water and low molecular weight gas stable at temperatures of roughly -10ºC to 25ºC and pressures of ~3 to 30 MPa in geologic systems.

Fine-grained particles (fines) commonly coexist with coarse-grained sediments that host gas hydrate. These fines can be mobilized by liquid and gas flow during gas hydrate production. Once mobilized, fines can clog pore throats and reduce reservoir permeability. Even where particle sizes are smaller than pore-throat sizes, clogs can form due to clusters of fines.

Fine-grained sediments, or "fines," are nearly ubiquitous in natural sediments, even in the predominantly coarse-grained sediments that host gas hydrates.
