TGS Announces Clari-Fi, a New Technique to Provide Broadband Seismic Data From Conventional Acquisition

HOUSTON, TX--(Marketwire - Jun 4, 2012) - TGS announces the release of Clari-Fi, a proprietary seismic data processing technique.

TGS' Clari-Fi technique allows broadband seismic to be generated from conventionally acquired seismic data. In order to achieve this, acquisition related frequency attenuation effects and the attenuation caused by the earth's filter must be addressed. TGS' proprietary Clari-Fi imaging technique enhances low and high frequencies and effectively solves for the earth's attenuation, resulting in images that are broadband and focused, thus improving the resolution of the data. This technique works with conventional streamer acquisition and so enables reprocessing of legacy data.

"The industry is increasingly recognizing the benefits of broadband data," says Zhiming Li, Senior VP Data Processing and Research & Development. "Broadband seismic provides greater richness of both robust low frequencies -- ideal for deep structure imaging and high frequencies -- which aid temporal resolution."
