Value Creation in Unconventional Plays Using Seismic

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.

EPISODE TRANSCRIPT
Erica Conedera: 00:12 Hello and welcome to Beneath the Subsurface a podcast that investigates the intersection of geoscience and technology. In our second episode, we'll deep dive into seismic technologies, pre-stack seismic attributes, acquisition developments, and our predictions for the future of seismic and the unconventional realm. From the software development department here at TGS. I'm Erica Conedera, your host and complete newcomer to the world of onshore seismic. I hope you'll find our discussion today as informative and enjoyable as I did.

Erica:
00:45
Um, so let's start with introductions to my left.

Jason Kegel
00:49
Yeah. My name is Jason Kegel. I've been with TGS for six years. I'm a geologist. I've worked on almost every one of the onshore US seismic programs that we have.

Erica:
00:59
Awesome.

Wayne Millice:
01:00
I'm Wayne Millice. I'm the gray beard of the group. I've been with TGS only about 11 years, but are, sorry, eight years. But I've been in the business about 35 years I'm the VP of onshore multiclient. And I'm here to hopefully teach some people about the value of seismic in our business.

Mike Perz:
01:19
I'm Mike Perz. I am the director of technology and the onshore group. So I'm responsible
