Abstract
A method is described for seismic imaging that may include receiving digital seismic data; processing the digital seismic data to create a digital seismic image in a seismic domain; flattening the digital seismic image to generate a digital flattened image; identifying artifacts in the digital flattened image; transforming the artifacts back into the seismic domain; and reprocessing the digital seismic data based on the artifacts in the seismic domain to generate a digital image with reduced artifacts. The method may be executed by a computer system.
Claims4
A computer-implemented method of seismic imaging, comprising:
- a. receiving, at a computer processor, digital seismic data;
- b. processing the digital seismic data to create processed digital seismic data and performing migration on the processed digital seismic data to generate a digital seismic image in a seismic domain;
- c. flattening the digital seismic image to generate a digital flattened image;
- d. identifying artifacts in the digital flattened image;
- e. transforming only the artifacts back into the seismic domain utilizing tau volume transformation;
- and
- f. reprocessing the digital seismic data based on the artifacts in the seismic domain to generate a digital image with reduced artifacts.
A computer system, comprising:
- one or more processors;
- memory;
- and
- one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions that when executed by the one or more processors cause the device to:
- receive, at the one or more computer processors, digital seismic data;
- process the digital seismic data to create processed digital seismic data and perform migration on the processed digital seismic data to generate a digital seismic image in a seismic domain;
- flatten the digital seismic image to generate a digital flattened image;
- identify artifacts in the digital flattened image;
- transform only the artifacts back into the seismic domain utilizing tau volume transformation;
- and
- reprocess the digital seismic data based on the artifacts in the seismic domain to generate a digital image with reduced artifacts.
A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by an electronic device with one or more processors and memory, cause the device to:
- receive, at one or more computer processors, digital seismic data;
- process the digital seismic data to create processed digital seismic data and perform migration on the processed digital seismic data to generate a digital seismic image in a seismic domain;
- flatten the digital seismic image to generate a digital flattened image;
- identify artifacts in the digital flattened image;
- transform only the artifacts back into the seismic domain utilizing tau volume transformation;
- and
- reprocess the digital seismic data based on the artifacts in the seismic domain to generate a digital image with reduced artifacts.
