Conventional NMO stack may result in lower resolution stacked sections due to distortions caused
by NMO correction and stretch muting. Treating the process of NMO and stack using regularized inversion
allows us to compute an optimal stack with higher frequency content. Low frequency content also plays
an important role in seismic data processing and imaging. As demonstrated by our numerical examples,
PWC stack has the ability to recover both higher and lower frequencies compared to conventional NMO and stack.
By implementing PWC stack, we gain resolution by utilizing signal from different offsets
and minimizing stretching effects.
The final stacked section has improved bandwidth and higher resolution, which may aid in interpretation
and inversion of small-scale features such as thin layers and diffractions.
