Speaker: Christof Stork
Interpreters can be frustrated by that land seismic data is often 10-100x noisier than marine data. There is room for optimism since source and receiver counts for land seismic data are each recently going up by about 10x. This increases total fold by about 100x, which is a revolution. But, there are still some significant noise issues the huge fold does not fix well: 1) consistent wavelet distortion of the near surface, 2) near surface scattering, 3) guided waves, 4) 3C noise, and 5) acquisition access issues. Because of the competitive & heuristic nature of land seismic acquisition and processing, these topics have been R&D starved. I will demonstrate the issues and show there is potential for significant technology improvements that are complementary with the new high fold data.
Speaker Biography: Christof Stork
Christof Stork started as a theoretical geophysicist with a Ph.D. in geophysics from Caltech in 1988 and then had a Postdoc at Stanford (SEP). He has done leading work on tomography and imaging. He has also been very practical during his employment at oil companies, service companies, and software companies. Christof is one of the few theoretical people who is taking a broad look at improving land seismic data beyond just using statistical methods. He has been involved with 4 startup companies, of which 3.5 were successful.
