Episode 227: How Experts Use Data and Technology to Navigate Subsurface Uncertainty

“Understanding the problem is sometimes often more important than getting to a solution.”

Madhav Vyas and Dr. David Lubo-Robles discuss June’s The Leading Edge on subsurface uncertainty.

In this episode, we talk about:

  • Methods for assessing uncertainty in seismic workflows
  • Significant sources of subsurface uncertainty
  • How integrating different data sources can reduce subsurface uncertainty
  • The concept of rugosity and its effect on seismic image resolution
  • The advantages of using invertible neural networks
  • How to better communicate uncertainty to stakeholders and management
  • Emerging technologies and methodologies to reduce subsurface uncertainty

In this conversation with host Andrew Geary, Madhav and David explore the complexities of predicting subsurface outcomes and the various sources of uncertainty that geophysicists must address. The discussion highlights how integrating geologic, petrophysical, and geochemical data can help reduce uncertainty and improve decision-making.

The episode also covers the impact of interface rugosity on wave propagation, methods for assessing uncertainty in seismic workflows, and the benefits of using invertible neural networks. Madhav also elaborates on how geophysicists can better communicate uncertainty to stakeholders and suggests looking to other industries, like meteorology, for effective communication strategies.

Listeners will gain insights into the challenges and solutions related to subsurface uncertainty, the importance of critical thinking in geoscience, and the potential of emerging technologies to improve subsurface predictions.
