| acoustic impedance |
a rock property that is the product of the compressional wave velocity in the rock multiplied by the rock's average density. The reflections recorded in a seismic data set are caused by changes in AI from one formation to the next. Seismic Inversion is the process of trying to estimate the AI distribution in the earth from the seismic data.
