Rock Physics: From Basics to the Validation of Advanced Seismic Technology Platforms

Five short webinars that focus on several aspects of rock physics are now available on-demand at https://www.pgs.com/techbyte. These address fundamental challenges related to the use of rock physics: How can we build robust saturated rock physics models of a heterogeneous earth? 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-to-no well control? Throughout the five-part mini-series, emphasis is given to rock physics being the bridge that connects geophysics and geology, and that guides QI efforts. Geologically-consistent rock models can be built that are augmented by FWI models, and FWI models can be reliably transformed into robust elastic low frequency models. With these platforms, various global case studies illustrate how carefully processed multisensor broadband seismic data can therefore be used to predict accurate lithology and fluid properties even when well control is poor.
