The SPG Mumbai Chapter introduced Dr. Bharath Shekhar, an Associate Professor at the Department of Earth Sciences, IIT Bombay. He holds an Integrated MSc in Exploration Geophysics from IIT Kharagpur and a PhD in Geophysics from the Center for Wave Phenomena, Colorado School of Mines. His expertise spans seismic imaging, ambient noise tomography, and the application of machine learning in geophysics. Dr. Shekhar is also the co- founder of Rezlytix Technologies Ltd., a company specializing in deep learning- based seismic super-resolution solutions.

Shri Vikas Mohan, President of SPG Mumbai Chapter delivered the opening remarks, emphasizing the challenges faced by traditional seismic data processing and interpretation methods in handling vast, complex datasets, reducing noise, and improving resolution to identify potential hydrocarbon reservoirs.

He highlighted the significance of integrating deep learning, particularly Convolutional Neural Networks (CNNs), into seismic imaging and interpretation. He also discussed how this technology enables faster, more accurate, and automated workflows, potentially reshaping the industry

Dr. Bharath Shekhar then delivered an insightful talk on "Supercharging Seismic Data Processing Workflows with Deep Learning.”
