Fluid-flow waves are shown to be responsible for the dispersion and attenuation at low frequencies; relations are derived by extending Gassmann's viewpoint to include coupling between fluid-flow waves and seismic body waves. This appears to be an important loss mechanism for heterogeneous porous rocks.<\/jats:p>","DOI":"10.1190\/1.1440520","type":"journal-article","created":{"date-parts":[[2002,10,11]],"date-time":"2002-10-11T15:35:06Z","timestamp":1034350506000},"page":"224-232","source":"Crossref","is-referenced-by-count":750,"title":["Computed seismic speeds and attenuation in rocks with partial gas saturation"],"prefix":"10.1190","volume":"40","author":[{"given":"J.
