Direct Hydrocarbon Indicators (DHI) and AVO - Virtual, Blended Short Course

Program Overview

This blended learning workshop provides an overview of AVO (Amplitude Variation with Offset) and DHI (Direct Hydrocarbon Indicator) techniques used in seismic data interpretation. Through self-paced modules and virtual instructor-led sessions, participants will learn the fundamentals of AVO/DHI, develop problem-solving skills, and enhance their understanding of rock physics and seismic jargon. The program targets geoscientists and professionals who need a basic understanding of seismic data utilization and communication.

• Faculty: Tom Temples

Other:

• This short course is designed to familiarize anyone using seismic data with the basics of what AVO and DHIs are and how they are used in an interpretation.
• One of the key goals is to explain the large and confusing amount of jargon that is used by the geophysical community when they use seismic data.
• This short course is part of the Basic Geophysics (BGP) program.
• Participants will learn how to:
• Explain the effect of hydrocarbons in the seismic data
• Detect hydrocarbons in the seismic data
• Describe rock physics
• Define amplitude variation with offset/angle (AVO/AVA)
• Make approximations to the Zoeppritz equations, including Aki-Richards equation and Shuey's equation
• Identify the Rutherford and Williams classification
• Describe slope, intercept, and the fluid line
• Describe the methods for prestack inversion, including Simultaneous Inversion; Elastic Impedance and Extended Elastic Impedance; Lambda Rho and Mu Rho
• This course is also available upon request as a private, on-site seminar.
