Abstract
Examples of methods and systems are disclosed. The methods may include obtaining, using a seismic processing system, seismic data regarding a subsurface region of interest and determining a plurality of first arrivals based on the seismic data. The methods may also include determining, using the seismic processing system, a plurality of filtered first arrivals by applying a modal filter and replacement interpolation to the plurality of first arrivals, and generating a seismic image based, at least in part, on the plurality of filtered first arrivals.
Claims20
A method, comprising:
- obtaining, using a seismic processing system, seismic data regarding a subsurface region of interest;
- determining, using the seismic processing system, a plurality of first arrivals based on the seismic data;
- determining, using the seismic processing system, a plurality of filtered first arrivals by applying a modal filter and replacement interpolation to the plurality of first arrivals;
- and
- generating, using the seismic processing system, a seismic image based, at least in part, on the plurality of filtered first arrivals.
A system comprising:
- a seismic processing system configured to:
- obtain seismic data regarding a subsurface region of interest, determine a plurality of first arrivals based on the seismic data,
- determine a plurality of filtered first arrivals by applying a modal filter and replacement interpolation to the plurality of first arrivals, and
- generate a seismic image based, at least in part, on the plurality of filtered first arrivals;
- and
- a seismic interpretation system configured to receive the seismic image and to determine a drilling target in the subsurface region based, at least in part, on the seismic image.
