Paper presented at the SEG/AAPG International Meeting for Applied Geoscience & Energy, August 28–September 1, 2022
Paper Number: SEG-2022-3747339
... Regional seismic networks typically monitor and locate seismic sources using only kinematic (i.e., traveltime) observations. We propose an automated “sliding box” procedure to improve source locations by leveraging dynamic (e.g., full waveform) information via Geometric-mean Reverse-Time...

Paper Number: SEG-2021-3594116
... Geometric-mean Reverse-time migration (GmRTM), a powerful crosscorrelation-based imaging method, generates higherresolution source images and is more robust to noise compared with conventional time-reversal imaging. The price to pay is the requirements of more accurate velocity models and much...

When Horton polled the audience at a recent talk, more than half of the respondents said they were using gun systems designed to orient the perforating charges at a target angle. “A year from...
