Hampson Russell Tutorial Link

The tutorial transitions from theory to application by addressing real-world seismic noise. It instructs users on how to generate (stacking multiple Common Depth Points to increase signal-to-noise ratio) and how to perform angle stacks (near, mid, and far). The key technical innovation taught here is the weighted stacking process to solve for intercept (A) and gradient (B).

The foundational hurdle in AVO analysis is the complexity of the Zoeppritz equations, which describe how seismic energy partitions at a boundary between two elastic media. The Hampson–Russell tutorials address this by immediately introducing the simplifying approximations—specifically the Aki-Richards and Shuey equations. Rather than overwhelming the user with matrix algebra, the tutorial breaks the AVO response into three fundamental components: intercept (A), gradient (B), and curvature (C). hampson russell tutorial

The tutorial is honest about the limitations here—specifically the ill-posed nature of the inverse problem (where multiple Earth models fit the same seismic data). It introduces and sparse-spike inversion as regularization techniques to stabilize the solution. The final output, such as the Lambda-Rho (incompressibility) versus Mu-Rho (rigidity) crossplot, provides the ultimate lithology-fluid discriminant. Gas sands show low Lambda-Rho (compressible) but moderate Mu-Rho, whereas shales show high values for both. The tutorial transitions from theory to application by
