Acoustic and elastic impedance sections have two main uses. Firstly, they “look more like geology” than traditional reflectivity data, and enable us to better communicate the subsurface images to our non-geoscientist colleagues (e.g., reservoir engineers and drillers). Secondly, inverted data can be directly calibrated to rock and fluid reservoir properties such as porosity, net-to-gross or net pay, facilitating its quantitative use.
