... (PSDM) test was performed where the final results from a traditional method using measured sonic logs were compared with the results when using a machine-predicted velocity field. Log prediction method and results Deep learning is a general term that's indicating that an algorithm is applied...

... Abstract Despite the now-routine use of prestack depth migration (PSDM) for unconventionals, confusion abounds on the topic of how to best incorporate near-surface velocity estimates into the PSDM shallow-model-building process. The present work seeks to eliminate the confusion via...

... for larger sample sizes; however, it's through a technically-sound methodology that the data can be analyzed at a granular level, illustrating the effectiveness of using a multidisciplinary approach. example show well control Imaging PSDM Reservoir Characterization depth migration URTeC...

... Summary A detailed benchmark study performed in 2016 demonstrates that pre-stack depth migration (PSDM) is superior to time-to-depth stretch of pre-stack time-migrated data (PSTM) even in structurally benign areas. Converting seismic data to depth by applying a time-to-depth stretch results...
