Beneath the Subsurface

Value Creation in Unconventional Plays Using Seismic

Season 1 : Episode 2

EPISODE SUMMARY

In the second episode of Beneath the Subsurface we pick back up with a deep dive into onshore seismic technology in unconventional plays. Wayne Millice, Mike Perz, and Jason Kegel dig through seismic technologies, pre-stack seismic attributes, acquisition developments, and our predictions for the future of seismic and the unconventional realm. Erica Conedera, your host, new to the onshore seismic world, explores the challenges and sometimes over-hyped solutions with onshore acquisition and processing with our guests.
