Industry Insights on Rock Physics

In the issue of Industry Insights, Andrew Long looks at rock physics, the bridge that connects geophysical attributes to geological properties. Most geoscientists who work with seismic data understand how subsurface contrasts in impedance cause seismic reflectivity to vary as a function of angle for incident wavefields. However, integrating these to make accurate predictions can be tricky.

Five short webinars that focus on several aspects of rock physics are now available in our TechByte webinar library.

In the issue of Industry Insights and its associated 5-part webinar series, Andrew Long looks at rock physics as the bridge between geophysics and geology, addressing fundamentals such as: How can we build robust saturated rock physics models? How can machine learning and geologically consistent rock physics modeling workflows reduce exploration uncertainty? How can FWI models augmented by rock-physics transformations overcome missing low frequencies? What low-frequency amplitude and phase issues in broadband seismic data are critical to rock physics estimation workflows? How can rock physics estimation workflows validate new seismic technology platforms in frontier areas with minimal-tono well control?
