FREG - Seismic Data Regularization

FREG provides a mathematically optimal alternative to standard regularization tools.

FREG™ benefits the exploration and production by

  • providing accurate seismic values for wave equation migration and multiple reflection attenuation.
  • estimating robust seismic amplitudes over small seismic data acquisition gaps.

FREG™ uses GeoEnergy's proprietary implementation of Prolate Spheroidal Wave Functions (PSWF) for interpolation and regularization of bandlimited seismic data.
