Strata performs both poststack and prestack inversions. In the conventional poststack domain, Strata analyzes poststack seismic volumes to produce an acoustic impedance volume. In the prestack domain, Strata analyzes angle gathers or angle stacks to produce volumes of acoustic impedance, shear impedance and density.
Poststack Inversion and Prestack Inversion
Benefits of inversion with Strata:
Seismic Inversion
Simultaneous inversion of prestack seismic data can be particularly useful for analyzing data with AVO anomalies.
Inversion Analysis
The inversion analysis tool shows the resulting inversion trace at each well location, overlain on top of the original impedance logs. It also shows the synthetic traces that result from the inverted data and compares them to the input seismic volume.
