Biography Citation SEG J. Clarence Karcher Award 2020
Siddharth (Sid) Misra is an associate professor with the Harold Vance Department of Petroleum Engineering at Texas A&M University. Prior to that, he was an assistant professor with the Mewbourne College of Earth and Energy at the University of Oklahoma. He develops computational methods to quantify the interaction of sensor physics with physical processes/properties of the subsurface to improve the exploration, development, and production of subsurface resources. As part of the latter work, Sid pioneered several geophysical methods and interpretation techniques that directly benefit the development and production of hydrocarbon reservoirs.
Thus far, Sid’s major technical contribution is in the theory of electromagnetic (EM) responses of geologic formations due to charge polarization phenomena. He conducted laboratory experiments, mechanistic modeling, and numerical simulations of instrument physics to quantify changes in electrical conductivity and dielectric permittivity of fluid-filled porous rocks due to polarization phenomena associated with clay and electrically conductive minerals. His research group introduced several techniques for processing multifrequency EM borehole measurements for the estimation of fluid saturations and to detect and quantify fractures and clay minerals in hydrocarbon-bearing formations.
During the last five years, Sid has been involved in the implementation of machine-learning methods for the interpretation of subsurface geophysical measurements. Funded by the U.S. Department of Energy, he developed techniques to process acoustic-emission waveforms and sonic traveltimes for the detection of geomechanically altered zones due to fractures and fluids. Furthermore, as part of his financial support received from the American Chemical Society, he develops machine-learning techniques for analysis of 2D/3D images to quantify connectivity of various rock solid and fluid constituents. The assessment of connectivity of material constituents enables better understanding of the transport of energy, mass, and momentum in porous rocks. A common thrust in his data-driven research efforts is to improve and expedite the interpretation of geophysical measurements and better visualize geophysical processes via advanced machine-learning methods.
Sid’s research results are being used currently by several oil and gas companies, including Chevron, Baker-Hughes, GE, Saudi Aramco, Hess, Schlumberger, and BHP Billiton. He is actively pursuing several impactful research projects in the area of machine learning applied to near-wellbore rock description using borehole geophysical measurements. His most recent research findings and interpretation workflows are documented in his book, Machine Learning for Subsurface Characterization. The book describes and implements data-driven interpretation methods and concepts needed to support today’s complex subsurface engineering problems.
I find it extremely fitting that SEG’s J. Clarence Karcher Award be bestowed to such an active, driven, creative, and intelligent young member of our academic community. I strongly believe that this is only the humble beginning of a very productive and transcendental geophysical career for Sid.
