Residual Static

The most successful algorithms available to us are:

  • Maximum power autostatics: Uses the objective function of maximum stack power to optimize the iterative decomposition of trace shifts.
  • Correlation autostatics: Uses the Gauss-Seidel technique for decomposing trace shifts into shot, receiver, channel and residual horizon velocity components.

Refraction Static

  • Application of statics calculated from laterally and vertically varying modelsof the near surface.
  • Tomographic arrival time inversion
  • Generalized reciprocal method
