Data Processing and Technology seismic modeling to simulate the results of a seismic survey under various source and receiver configurations. Nucleus+ is the most comprehensive planning package on the market and is widely used throughout the oil and gas industry. At PGS, the unique holoSeis visualization technology is an integral part of the complete seismic workflow — from quality control of seismic data during acquisition, to the building of complex velocity models for pre-stack depth migration and visualization of the end product for customers. PGS’ holoSeis is in daily use at Company facilities worldwide, including onboard survey vessels. More than 500 holoSeis systems have been installed under license at customers’ offices and field locations. PGS holoSeis package is a preferred tool for visualization and interpretation of exceptionally large volumes of 3D seismic data Processing Technology PGS has invested considerable resources to develop and deliver efficient data processing solutions and technological differentiators to its clients. In the realm of time processing, this has included a client-rated “best in class” 3D Surface-Related Multiple Elimination (SRME). PGS has also developed a proprietary suite of multi-dimensional regularization algorithms and technologically advanced solutions for the automated selection of dense velocity fields. Optivel is one of these proprietary solutions. Optivel uses a generic algorithm to quickly provide the optimum velocity and anisotropic parameter fields for use on very dense processing grids. Development projects also focus on methods that ensure that each processing project is completed at optimum efficiency — which reinforces PGS’ value proposition of delivering outstanding quality and cost effectiveness. and down-going components and uses the data to build industry-leading velocity models which result in superior depth-migrated images. The additional signal energy in the low-frequency range also benefits full waveform inversion, an automated method to refine seismic velocity models. Additional cascaded benefits are realized in later stages involving data interpretation and reservoir characterization. Intellectual Property PGS’ patents, trademarks, service marks, copyrights and licenses protect its proprietary technology. The Company’s intellectual property rights include the Ramform TM seismic vessels, GeoStreamer ® , Multi-Transient Electro Magnetic (MTEM TM ), OptoSeis® and HD3D ® seismic solution software, PGS hyperBeam ® and GeoSource ® . The Company’s intellectual property rights collectively represent a material business asset. As of December 31, 2011, PGS held 305 patents under the laws of the U.S., U.K., and Norway — an increase of 52 new patents in these jurisdictions during 2011. Additional patent-protected innovations help sharpen and preserve the competitive advantages achieved by PGS through technological differentiators. PGS offers GeoStreamer as an integrated acquisition and processing solution that delivers unparalleled features that differentiate the Company’s product capabilities from industry alternatives. The Company has developed proprietary technology and built up considerable know-how concerning the generation of up-going pressure wavefield data (P-UP) and full processing through to final product delivery. Workflows have been implemented to match the new generation of GeoStreamer and GeoStreamer GS survey data with non-GeoStreamer legacy data in the context of 4D processing. Full backward compatibility has been demonstrated. PGS data processing techniques have been enhanced to take full advantage of the additional low-frequency signal content of GeoStreamer GS surveys. For example, data processing separates the wave field into up- 36 PGS Annual Report 2011
Data Processing and Technology Operations GeoStreamer GS : A New Era of Ghost-free Broadband Seismic Data Seismic data acquired without source or receiver sea-surface reflections (ghosts) yield subsurface seismic images of unprecedented quality. Ghostfree GeoStreamer GS technology removes the noise components that have historically plagued marine streamer seismic surveys. the ultimate expression of geological structure, stratigraphy and fluid distribution. GeoStreamer GS technology is scheduled to be available in 3D in most regions of the world by year-end 2012. In 2007, PGS solved a 40-year-old industry problem by eliminating the receiver ghost through the use of the Company’s unique dual-sensor solution, GeoStreamer. Deploying GeoStreamer acquisition, results in seismic data with considerably broader frequency bandwidth and resolution than conventional seismic data. Immune to receiver ghosts, GeoStreamer is towed at depths of 15 to 25 meters. Greater towing depth significantly increases operational efficiency while greatly reducing surface-induced noise — additional unique advantages of GeoStreamer. At the EAGE conference in Vienna in 2011, PGS announced development of GeoSource, which removes the source ghost, and the resultant combined product offering: GeoStreamer GS. By deploying GeoStreamer GS technology, both source and receiver ghosts can be completely removed, thus revealing the true earth response, Conventional GeoStreamer GeoStreamer GS Conventional GeoStreamer GeoStreamer GS GeoStreamer GS offers significantly improved data quality compared to a conventional data set.
