  • Methane gas hydrate effect on sediment acoustic and strength properties 

    Winters, William J.; Waite, William F.; Mason, D. H.; Gilbert, L. Y.; Pecher, I. A. (2006-04-08)
    To improve our understanding of the interaction of methane gas hydrate with host sediment, we studied: (1) the effects of gas hydrate and ice on acoustic velocity in different sediment types, (2) effect of different ...
  • Methane hydrate formation in partially water-saturated Ottawa sand 

    Waite, William F.; Winters, William J.; Mason, D. H. (Mineralogical Society of America, 2004-08)
    Bulk properties of gas hydrate-bearing sediment strongly depend on whether hydrate forms primarily in the pore fluid, becomes a load-bearing member of the sediment matrix, or cements sediment grains. Our compressional ...
  • Physical properties of hydrate-bearing sediments 

    Waite, William F.; Santamarina, J. Carlos; Cortes, Douglas D.; Dugan, Brandon; Espinoza, D. N.; Germaine, J.; Jang, J.; Jung, J. W.; Kneafsey, Timothy J.; Shin, H.; Soga, K.; Winters, William J.; Yun, T.-S. (American Geophysical Union, 2009-12-31)
    Methane gas hydrates, crystalline inclusion compounds formed from methane and water, are found in marine continental margin and permafrost sediments worldwide. This article reviews the current understanding of phenomena ...
  • Physical properties of sediment from the Mount Elbert Gas Hydrate Stratigraphic Test Well, Alaska North Slope 

    Winters, William J.; Walker, Michael; Hunter, Robert; Collett, Timothy S.; Boswell, Ray M.; Rose, Kelly K.; Waite, William F.; Torres, Marta E.; Patil, Shirish; Dandekar, Abhijit (Elsevier B.V., 2010-01-18)
    This study characterizes cored and logged sedimentary strata from the February 2007 BP Exploration Alaska, Department of Energy, U.S. Geological Survey (BPXA-DOE-USGS) Mount Elbert Gas Hydrate Stratigraphic Test Well on ...
  • Physical property changes in hydrate-bearing sediment due to depressurization and subsequent repressurization 

    Waite, William F.; Kneafsey, Timothy J.; Winters, William J.; Mason, D. H. (American Geophysical Union, 2008-07-03)
    Physical property measurements of sediment cores containing natural gas hydrate are typically performed on material exposed, at least briefly, to non-in situ conditions during recovery. To examine the effects of a brief ...
  • Simultaneous determination of thermal conductivity, thermal diffusivity and specific heat in sI methane hydrate 

    Waite, William F.; Stern, Laura A.; Kirby, S. H.; Winters, William J.; Mason, D. H. (Blackwell Publishing, 2007-03-11)
    Thermal conductivity, thermal diffusivity and specific heat of sI methane hydrate were measured as functions of temperature and pressure using a needle probe technique. The temperature dependence was measured between −20°C ...
