Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3594976
... The multivariable nature of oil and gas operations makes it difficult for operators to detect and correct inefficiencies, which is critical to meeting carbon-neutrality goals. Machine learning-powered predictive analytics can help operators reduce carbon emissions by detecting abnormalities...

.... Combining this property with the locality property of the pulsed-beams, we obtain a novel migration formulation that reduces the number of backpropagation operations needed to form a good image. Finally, we show a relation between the beam amplitudes and the subsurface properties by using a physical model...
