Data Science Applications in Geophysical Interpretation


Machine learning approaches to geophysical interpretation have recently shown success in automating the identification of structures in seismic data, which in turn can help reduce the time required for the interpretation life-cycle.

I have started to contribute to Landmark’s research team in areas of image segmentation, feature extraction, pattern recognition in salt body detection, fault plane prediction, and multi-facies classification. My experience also includes seismic processing, seismic modeling, inversion, and migration. I have been granted multiple U.S. patents and have several U.S. pending patents. During my research in academia and industry, I have published over 30 peer-reviewed technical papers and gave presentations at different geophysical conferences. Please check out other pages for more detailed projects, publications, and patents.

Below are my recent research and related papers. Some papers are still In Press and will be published soon:
