Abstract
A method includes receiving seismic data for a geologic region of the Earth; building a velocity model of the geologic region of the Earth; selecting at least one mode of multiple and corresponding travel time data from a data storage where the travel time data correspond to at least one complex ray signature in the geologic region of the Earth and are based at least in part on the velocity model; performing migration on the seismic data using at least the selected travel time data to generate processed seismic data; and rendering an image of the geologic region of the Earth to a display where the image includes at least a multiple image.
Claims20
A method comprising:
- receiving seismic data for a geologic region of the Earth;
- building a velocity model of the geologic region of the Earth;
- selecting at least one mode of multiple and corresponding travel time data from a data storage wherein the travel time data correspond to at least one complex ray signature in the geologic region of the Earth and are based at least in part on the velocity model;
- performing migration on the seismic data using at least the selected travel time data to generate processed seismic data;
- and
- rendering an image of the geologic region of the Earth to a display wherein the image comprises at least a multiple image based at least in part on the processed seismic data.
A system comprising:
- a processor;
- memory accessible by the processor;
- and
- processor-executable instructions stored in the memory that are executable to instruct the system to:
- receive seismic data for a geologic region of the Earth;
- build a velocity model of the geologic region of the Earth;
- select at least one mode of multiple and corresponding travel time data from a data storage wherein the travel time data correspond to at least one complex ray signature in the geologic region of the Earth and are based at least in part on the velocity model;
- perform migration on the seismic data using at least the selected travel time data to generate processed seismic data;
- and
- render an image of the geologic region of the Earth to a display wherein the image comprises at least a multiple image based at least in part on the processed seismic data.
One or more computer-readable storage media comprising computer-executable instructions executable to instruct a computer to:
- receive seismic data for a geologic region of the Earth;
- build a velocity model of the geologic region of the Earth;
- select at least one mode of multiple and corresponding travel time data from a data storage wherein the travel time data correspond to at least one complex ray signature in the geologic region of the Earth and are based at least in part on the velocity model;
- perform migration on the seismic data using at least the selected travel time data to generate processed seismic data;
- and
- render an image of the geologic region of the Earth to a display wherein the image comprises at least a multiple image based at least in part on the processed seismic data.
