Abstract
The well-known Biot-Gassmann equation for the fluid dependence of incompressibility of a porous rock is in error. However, a recent numerical calculation on a simple rock model verifies that equation. The calculation appears to be correct, but constitutes a special case, not representative of real rock. Physical experimentation on actual rocks is required to verify the corrected theory.
期刊介绍：
Geophysics, published by the Society of Exploration Geophysicists since 1936, is an archival journal encompassing all aspects of research, exploration, and education in applied geophysics.
Geophysics articles, generally more than 275 per year in six issues, cover the entire spectrum of geophysical methods, including seismology, potential fields, electromagnetics, and borehole measurements. Geophysics, a bimonthly, provides theoretical and mathematical tools needed to reproduce depicted work, encouraging further development and research.
Geophysics papers, drawn from industry and academia, undergo a rigorous peer-review process to validate the described methods and conclusions and ensure the highest editorial and production quality. Geophysics editors strongly encourage the use of real data, including actual case histories, to highlight current technology and tutorials to stimulate ideas. Some issues feature a section of solicited papers on a particular subject of current interest. Recent special sections focused on seismic anisotropy, subsalt exploration and development, and microseismic monitoring.
The PDF format of each Geophysics paper is the official version of record.
