The 2021 SEG Reginald Fessenden Award [1]

Boris Gurevich is recognized by the Reginald Fessenden Award for his technical contributions to rock physics, in particular to the theory of seismic attenuation and dispersion in fluid-saturated porous rocks. This subject is of major importance in applied geophysics because attenuation and dispersion significantly influence seismic amplitudes and waveforms. This understanding of wave propagation in attenuative media is vital to the characterization of rocks and fluids from seismic data.

Boris Gurevich has been among the most prominent rock physicists in the SEG community for a long time, and his influential work richly deserves to be recognized by the Fessenden Award. Boris received his PhD in 1988 from the Institute of Geosystems in Moscow, Russia. He joined Curtin University in Perth, Australia, in 2001, and there he currently serves as John Curtin Distinguished Professor and director of the Centre for Exploration Geophysics and of the Curtin Reservoir Geophysics Consortium.

Boris has made a number of key contributions to the development of rigorous theoretical models of seismic attenuation and dispersion within the framework of the poroelasticity theory. In particular, together with his colleagues and students, he has devised a comprehensive theory of seismic dissipation due to wave-induced flow of pore fluids caused by spatial heterogeneities in rock compliance, such as fractures or gas patches. In recent years, Boris' team has also developed a new theoretical model for attenuation and dispersion caused by pore-scale fluid-pressure relaxation between pores and compliant grain contacts, also known as squirt flow. They have extended this model to rocks saturated with solid and viscoelastic substances, such as heavy oil.

Another important recent contribution of Boris' team is derivation of the rigorous bounds on attenuation and dispersion in fluid-saturated rocks. This result provides a useful recipe for quality control of experimental measurements and theoretical estimates of attenuation and dispersion in porous media.

While most of Boris' scientific contributions are theoretical, he appreciates the value of experimental data and always strives to bring rock physics closer to applications. To this end, he has founded a rock physics laboratory at Curtin University, which is well known for developing new efficient ways of measuring rock properties. Boris also cooperates closely with his university colleagues and industrial partners in developing innovative ways of using seismic amplitudes for subsurface characterization and monitoring.

The significance of Boris's research lies in the fact that attenuation is ubiquitous in the subsurface. However, it is still largely ignored in seismic exploration or treated as a nuisance that needs to be compensated for. Yet it has been clear for some time that attenuation is controlled by the pore fluid and hydraulic properties of rocks. Whereas dissipation-related seismic attributes are sometimes employed in seismic interpretation and reservoir characterization, this is mostly done in an empirical and qualitative manner. Theoretical models of frequency-dependent attenuation and dispersion spearheaded by Boris help establish quantitative links between observations and material properties. This should lead to improved geophysical characterization and monitoring of fluid-saturated reservoirs in exploration and production of energy and water resources, as well as in geologic storage of CO2. Many of Boris' results are summarized in an upcoming book (coauthored by José Carcione) to be published by SEG.

Boris is always generous in sharing his keen scientific insights, not just with his peers but also with students. Despite carrying a large administrative load at Curtin, he devotes a lot of time to student mentoring and advising. In 2019, he took time from his research to tour the Asia-Pacific region as an SEG Honorary Lecturer. Boris is one of the most outgoing people we have ever met and has a great sense of humor that comes in handy even in heated scientific discussions. We are looking forward to his future contributions!
