Land Data Regularization and Interpolation Using Azimuth Moveout (AMO)

Azimuth Moveout (AMO) is a wave-equation correct binning algorithm that accurately handles dipping geological strata and variable velocities. AMO has applications for both marine and land data, though this paper focuses mainly on the application of AMO to 3-D and 2-D land surveys which have irregular and sparse geometry that often leads to spatial aliasing. AMO can be successfully used to regularize and interpolate land data, while preserving steep dips and diffractions better than standard binning.<br>Traditionally, AMO was designed to address the marine acquisition shortcomings, and regularize the data. Recent focus by exploration and production companies to exploit shallow resource plays has demanded new research into utilizing existing 3D data for mapping the shallow reservoirs. The land examples provided in this paper demonstrate the success of applying AMO to conventional land 3-D data.<br>
