about these developments, but we are very focused on bringing them to the market.    You mentioned earlier the focus on producing photo-quality imaging. Will you discuss some of the evolutions that have recently taken place in this area? FC: Most of our new products are based on broadband technology which allows the image to have a much deeper, richer, tonal quality. Complementing this architecture is a number of signal and display processing improvements which further enhance the imagery.   Where do you see the greatest opportunities for growth? FC: From our perspective

PGS 2D and 3D surveys in Eastern Canada

PGS : Building Further Success in Newfoundland, Labrador

recently completed the fifth consecutive acquisition season offshore Newfoundland and Labrador as part of the ongoing joint venture (JV) with TGS. The successful 2015 season was the biggest yet with PGS operating four vessels, two 3D and two 2D vessels, all of them equipped with GeoStreamer, PGS' broadband technology. This season marked the commencement of the first MultiClient 3D programs to be acquired by the JV, as well as continued building of the regional MultiClient 2D library coverage. There were a number of other "firsts" associated with this year's seismic season:   * First MultiClien

Broadband Seismic for Enhanced Pre-salt Imaging

almost a decade for the first deepwater wells to be drilled offshore Brazil and these were targeting post-salt prospects. Only after the turn of the century did seismic surveys begin to deliver higher quality data needed for deepwater pre-salt formation analysis, and only around 2004-2005 was the Broadband technology first applied to seismic surveys in the Santos Basin, which led to the discovery of the Lula field (at the time named Tupi). By then the quality of the seismic data allowed, Petrobras and partners to confidently commit to the hugely expensive drilling of the first pre-salt pilot well. Before

CGG secures contracts for 3D seismic acquisition of four major surveys

CGG Nets Quartet of BroadSeis-BroadSource Marine Contracts

  French Firm CGG announced today that it has been awarded contracts for the 3D seismic acquisition of four major surveys using its BroadSeisTM with BroadSourceTM, marine broadband technology. The four surveys represent a total contract value of over 80 million USD. Three of the surveys have been awarded in the Asia-Pacific region, with two offshore Malaysia and one offshore NW Australia, while the fourth is to be acquired offshore West Africa. Jean-Georges Malcor, CEO, CGG, said: "Only CGG’s BroadSeis-BroadSource technology delivers full-bandwidth broadband data. These

with its accompanying strong customer support is confirmation of TGS' strategy in growing our library in this region over the past several years," commented Stein Ove Isaksen, Senior VP Eastern Hemisphere for TGS. Data processing will be performed by TGS using its proven proprietary broadband technology, Clari-FiTM.  TGS add that the first season of data will be available to clients in Q1 2015. The survey is supported by industry funding.

3D library in the region, bringing the total volume of recent TGS 3D in the area to more than 17,500 km2. The broadband seismic data will be acquired by the M/V Polarcus Naila towing 12 streamers at 6,000 m cable length. Data processing will be performed by TGS using its proven proprietary broadband technology, Clari-FiTM.  Initial data will be available to clients in Q4 2014. "TGS is pleased to announce the industry's first 3D data over the Brendan Basin in UKCS Quad 219" commented Stein Ove Isaksen, Senior VP Eastern Hemisphere for TGS.
