Abstract: A wellbore is drilled in a formation using a drill string assembly that includes a drill string. A drill bit is connected to a downhole end of the drill string. A notching tool is connected to the drill string. After drilling the wellbore to a depth from a surface in the formation, the drilling is paused.

Abstract: Disclosed are methods, systems, and computer-readable medium for a full seismic wavefield de-aliasing workflow. To achieve the de-aliasing, the workflow employs a four-dimension (4D) anti-leakage anti-aliasing regularization algorithm. The workflow involves application of successive de-aliasing steps while restricting computations only to the significant spatial dimensions. In areas of strong elastic property variation in the near-surface, the benefit of de-aliasing the full wavefield is both significant and demonstrable. In addition to achieving de-aliased sampling of the full wavefield, the workflow reduces the complexity of both the computational and geophysical aspects of the problem of de-aliasing full wavefields.
