Abstract
A technique includes processing first data indicative of a first image of a subsurface region of interest on a machine to generate second data indicative of a second image. The first image is derived from measurements of seismic waves, which propagate in a plurality of directions, and the second image is generated by partitioning the first image based on the directions. The technique includes processing the second data to determine a dip decomposition for each of the directions; and based on the dip decompositions and the directions, generating an angle domain common image gather.
Claims17
A method comprising:
- processing first data representing a first image of a subsurface region of interest on a machine to partition the first image to generate second data representing a second image, wherein the first image is derived from measurements of seismic waves and the partitioning comprising partitioning the first image according to one of a source wavefield direction or a receiver wavefield direction without partitioning the first image according to the other of the source wavefield direction and the receiver wavefield direction;
- processing the second data to determine a dip decomposition for each of the directions associated with the partitioning;
- and
- based on the processing of the second data, generating an angle domain common image gather.
An article comprising a computer readable storage medium to store instructions that when executed by a computer cause the computer to:
- process first data representing a first image of a subsurface region of interest to generate second data representing a second image, the first image being derived from measurements of seismic waves and the second image being generated by partitioning the first image according to one of a source wavefield direction or a receiver wavefield direction;
- process the second data to determine a dip decomposition for each of the directions associated with the partitioning;
- and
- based on the processing of the second data, generate an angle domain common image gather.
A system comprising:
- an interface to receive first data representing a first image of a subsurface region of interest derived from measurements of seismic waves;
- and
- a processor to:
- process the first data to partition the first image according to a source wavefield direction or a receiver wavefield direction to generate second data representing a second image;
- process the second data to determine a dip decomposition for the direction associated with the partitioning;
- and
- based on the processing of the second data, generate an angle domain common image gather.
