Guest Speaker: Tariq A. Alkhalifah

Tariq A. Alkhalifah is a professor in the Physical Sciences and Engineering Division. He joined KAUST in June 2009. Before he joined KAUST, Alkhalifah was research professor and director of the Astronomy and Geophysics Research Institute at King Abdulaziz City for Science & Technology (KACST). Previously, he held the positions of associate research professor, assistant research professor, and research assistant at KACST. From 1996 to 1998, Alkhalifah served as a postdoctoral researcher for the Stanford Exploration Project at Stanford University, United States. He received the J. Clarence Karcher Award from the Society of Exploration Geophysicists (SEG) and the Conrad Schlumberger Award from the European Association for Geoscientists & Engineers (EAGE) in 2003, and honorary lecturer for the SEG in 2011. Alkhalifah is a member of SEG and of EAGE. Alkhalifah received his doctoral degree in geophysics and his master’s degree in geophysics, both from the Colorado School of Mines, United States. He holds a bachelor’s degree in geophysics from King Fahd University of Petroleum and Minerals, Saudi Arabia.

What does it take to illuminate the Earth at all scales?

With a focus on reservoir illumination

Tariq Alkhalifah

The propagation of vibrational energy (waves) inside the Earth, when recorded, has proven to be a valuable source of information about the Earth interior. We deemed the outer core of the Earth, at a depth of 2900 km, to be made up of molten Iron and Nickel, mostly thanks to the information embedded in recorded seismic waves.  The deepest whole humans managed to drill inside the Earth is only around 15 km deep. Seismic waves through its interaction with the earth interior, including scattering, carries crucial information about the Earth’s elastic properties.  At the near surface of the Earth, where resource exploration enthusiast interest resides, seismic waves are the main tool for locating, mapping and characterizing subsurface resources. Our job, as seismic users, is to provide the resource developers with a picture of the structure of the subsurface, through imaging, and more recently, its content at reasonable resolution, through waveform tomography. Advances in our ability to computationally handle multi scattered waveform types provided additional Earth illumination possibilities. Such possibilities are even better realized in the very near surface of the Earth, the part we reside directly over, as we assess hazard and explore for water and mining resources among other applications. My group at King Abdullah University for science and technology (KAUST) are devoted to advance our knowledge in enhancing the computational tools that allow us to utilize recorded seismic data to delineate the Earth at all scales. This includes taking the more accurate, but complex, physics into consideration in waveform inversion, as well as, utilizing additional information in our data including the often-ignored multi-scattered energy. Our innovative tools applied to active and passive seismic data have resulted in improved images of the subsurface. In this presentation, I will show results of applying our technologies on real acquired seismic data.
