Conclusions

We have developed a method to efficiently and robustly flatten 3D seismic cubes. This method uses an efficient implementation of the Fast Fourier transform within a non-linear iterative scheme. We demonstrated its effectiveness on a series of synthetic and field test cases.

Data cubes with vertical, laterally limited faults can be flattened by applying a residual weight. This allows horizons to be tracked across these faults.

We envision a tool that can be quickly and easily implemented by interpreters exploiting its superior computational performance. This method can provide an initial picking that interpreters can then adjust.
