Thin beds, tuning, and AVO

Wes Hamlyn explores two topics that are particularly relevant to quantitative seismic interpretation, such as thin-bed tuning and AVO analysis. He specifically examines the impact of thin beds on pre-stack seismic amplitudes and subsequent effects on AVO attribute values. Tuning refers to the modulation of seismic amplitudes due to constructive and destructive interference from overlapping seismic reflections. This phenomenon commonly occurs when a down-going wave is reflected from multiple closely spaced interfaces. The wedge model is a standard tool available with the interpreter to examine this phenomenon.
