Shallow Velocity Model Building Considerations for Prestack Depth Migration in Unconventionals
Available to Purchase
Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, July 22–24, 2019
Paper Number: URTEC-2019-399-MS
... 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...

Seismic Post-stack and Pre-stack Impedance Inversions in Depth, Examples From the Woodford Formation, Anadarko Basin
Available to Purchase
Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, July 24–26, 2017
Paper Number: URTEC-2691074-MS
... 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...
