Abstract
A method can include selecting a location associated with a seismic survey geometry; selecting a trace for the location where the trace is selected from one of a plurality of different types of traces that include real data traces, interpolated data traces and model data traces; generating a multiple model based at least in part on the selected trace; and adjusting seismic data based at least in part on the multiple model.
Claims20
A method of improving seismic image data processing, the method comprising:
- receiving real data traces acquired via seismic acquisition equipment according to a seismic survey geometry for a geologic region wherein each of the real data traces comprises a series of values representing seismic energy with respect to a corresponding series of times or depths and wherein real data trace coverage gaps exist within the seismic survey geometry;
- generating model data traces from a seismic image;
- selecting locations associated with the seismic survey geometry for the geologic region;
- selecting a trace for each of the locations wherein each trace is selected from one of a plurality of different types of traces that comprise the real data traces, interpolated data traces and the model data traces and wherein at least one distance criterion is utilized for determining whether to select one of the interpolated data traces or one of the model data traces for one of the locations in one of the coverage gaps;
- generating a multiple model using the selected traces;
- adjusting seismic image data for the geologic region using the multiple model to generate improved seismic image data for the geologic region;
- and
- rendering an image of spatial relations of structures of the geologic region to a display using the improved seismic image data.
