Abstract
A method can include receiving seismic survey data of a subsurface environment from a seismic survey that includes a source arrangement of sources that is spatially denser than a receiver arrangement of receivers; processing the seismic survey data using the principle of reciprocity for performing interpolation across the receivers to generate processed seismic survey data; and generating an image of at least a portion of the subsurface environment using the processed seismic survey data.

A method comprising:
- receiving seismic survey data of a subsurface environment from a seismic survey that comprises a source arrangement of sources that is spatially denser than a receiver arrangement of receivers;
- processing the seismic survey data by performing interpolation across the receivers using the principle of reciprocity to generate processed seismic survey data, wherein the processed seismic survey data includes interpolated seismic survey data;
- deriving priors from non-aliased low-frequency spectrum of the interpolated seismic survey data using the principle of reciprocity;
- distinguishing between aliased and true events in the processed seismic survey data based at least partially on the priors;
- and
- generating an image of at least a portion of the subsurface environment using the true events in the processed seismic survey data.
A system comprising:
- a processor;
- memory operatively coupled to the processor;
- and
- processor-executable instructions stored in the memory to instruct the system to:
- receive seismic survey data of a subsurface environment from a seismic survey that comprises a source arrangement of sources that is spatially denser than a receiver arrangement of receivers;
- process the seismic survey data by performing interpolation across the receivers using the principle of reciprocity to generate processed seismic survey data, wherein the processed seismic survey data includes interpolated seismic survey data;
- derive priors from non-aliased low-frequency spectrum of the interpolated seismic survey data using the principle of reciprocity;
- distinguish between aliased and true events in the processed seismic survey data based at least partially on the priors;
- and
- generate an image of at least a portion of the subsurface environment using the true events of the processed seismic survey data.
One or more computer-readable storage media comprising computer-executable instructions executable to instruct a computing system to:
- receive seismic survey data of a subsurface environment from a seismic survey that comprises a source arrangement of sources that is spatially denser than a receiver arrangement of receivers;
- process the seismic survey data by performing interpolation across the receivers using the principle of reciprocity to generate processed seismic survey data, wherein the processed seismic survey data includes interpolated seismic survey data;
- derive priors from non-aliased low-frequency spectrum of the interpolated seismic survey data using the principle of reciprocity;
- distinguish between aliased and true events in the processed seismic survey data based at least partially on the priors;
- and
- generate an image of at least a portion of the subsurface environment using the true events of the processed seismic survey data.
