Azimuth MoveOut (AMO)
Arcis Corporation in conjunction with 3DGEO is pleased to offer Azimuth Moveout (AMO) a new wave equation propagation algorithm. The concept of AMO was developed at Stanford University by Biondo Biondi, one of the principals of 3DGEO. The AMO operator rotates the azimuth and modifies the offset of 3D pre stack data. It is analytically derived by cascading the forward and inverse 3D DMO.
When effectively applied AMO can be used to reduce the computational cost of 3D pre stack imaging and for regularizing and interpolating poorly sampled 3D data.
Accurate Interpolation
AMO can be used to interpolate unevenly and irregularly sampled 3D data by filling acquisition gaps and balancing input data. AMO carries the correct kinematic, phase and amplitude transformation because it is strictly derived from the wave equation. The dipping events are moved correctly when transforming or interpolating the data, in a manner that is consistent with the wave equation. This property sets AMO apart as a seismic interpolator from more conventional ones.
AMO transforms 3D pre-stack data with a given offset and azimuth to equivalent data with different offset and azimuth. The AMO operator is derived by collapsing in one single step the cascade of an imaging operator and a forward modeling operator. AMO is not a single-trace to single trace transformation, but it is a partial-migration operator that moves events across midpoints according to their dip.
Arcis is the exclusive provider of AMO services in Calgary, Canada.
