Title: ACQUISITION AND REGULARIZATION OF NON-UNIFORM SEISMIC DATA
Abstract:
Provided in some embodiments are systems and associated methods for regularizing seismic data. Embodiment include obtaining non-uniformly sampled seismic data (e.g., generated by real seismic sensor array having an un-even distribution of real seismic sensors physically positioned proximate a subsurface formation), interpolating the non-uniformly sampled seismic data (e.g., using a Lagrange interpolation or non-linear interpolation) to generate regularized seismic data representing a regular distribution of seismic sensors, and generating, using the regularized seismic data, a seismic image of the subsurface formation.
