The Relationship between AVO and Petrophysics

DAVID GRAY SVP INTEGRATED STUDIES, GEOMODELING TECHNOLOGY CORP, FDAVID.GRAY@GMAIL.COM Purpose The main purpose of this article is to provide geoscientists with one source which uncovers the connection between pre-stack seismic gathers and the petrophysical properties that cause amplitude versus offset (AVO) variations in them. There are many seismic AVO equations in the literature, all parameterized differently, e.g., Shuey (1985), Smith and Gidlow (1987), Verm and Hilterman (1994), and Gray et al (1999). This paper attempts to reconcile these parameterizations by presenting all of these existing equations using common parameters which are defined in Appendix A. Table 1 lists all the [...]

Associate Editor’s Column – Farewell, and see you soon

DAVID GRAY | ASSOCIATE EDITOR, CSEG RECORDER, FDAVID.GRAY@GMAIL.COM | After two fun years working with a great group of people, I’m leaving my role as Associate Editor of the CSEG Recorder. This will not be the last you hear from me though, as after working here, I am inspired to publish even more in this great magazine that we are very lucky to have. A couple of years ago, after leaving Ikon thanks to Covid and recovering from working for 35 years, I knew that I needed to continue to be involved in geophysics. Working for the Recorder scratched that [...]
