1 408UL TITRE SEISMIC ACQUISITION All-Terrain Vibrators SYSTEM The most popular system in the world

2 408UL Recognized for the strength and reliability of its components, the 408UL acquisition system has dominated the seismic industry since it s entry into the market. Heavily used by seismic contractors, trusted by acquisition crews, and successful in all parts of the world; this system has proven itself the most popular seismic acquisition system in the world. Sophisticated Ground Equipment You are no longer restricted by design limitations. The 408UL ground equipment, enables you to create the best solution for your operational and safety needs. Modify the confi guration from job to job, whether it s 2-D, 3-D or 3-C. Flexible Telemetry You are no longer restricted by the limitations of traditional telemetry. A brilliant approach to combined telemetry, named Seismic Areal Network, provides complete fl exibility offering an effi cient solution for today s complex operational problems. Powerful Software In order to support its technological advances in telemetry, the 408UL system software, named Seismic Network Software, is distributed throughout the complete seismic array as well as the central unit. Reliability beyond expectations Spend even less time troubleshooting and more time recording. In any environment from deserts to transition zones, the years of experience the 408UL has spent in the fi eld have demonstrated its unmatched reliability.

3 408UL Sophisticated Ground Equipment The Sercel Link consists of a set of between 1 and 48 extremely small acquisition units (FDU s), integrated with a small diameter cable with a connector at each end. The cable and the acquisition units are handled together as one unit enabling you to defi ne the characteristics of the system to match your support infrastructure. The Link has been specifi cally designed to enable you to modify the confi guration from job to job, whether it is 2-D, 3-D or 3-C. This truly fl exible solution can be adapted to meet all of your operational and safety requirements. The Link offers further adaptability by directly connecting sensors into the acquisition unit, thereby eliminating takeouts. The sensor can also become a part of the acquisition unit, accommodating digital accelerometers. The choice is yours. Signifi cant reductions in size, weight and lower power requirements will not only result in greater portability, but will also reduce operating costs, thereby helping to fund the system purchase. The 408UL Ground equipment can be used with the new 428XL Acquisition System. Cable and FDU s handled as one unit Smallest size and lowest weight of the entire system No analog data within the cable Variable confi guration Lowest power ever on any system Digital sensors

4 408UL FLEXIBLE TELEMETRY A true multi-mode approach to seismic acquisition The total seismic array not only becomes a path for data and commands but supports a communications protocol which allows the 408UL to act as a computer network in addition to the standard functions of transmitting data and commands. We call this the Seismic Areal Network. Data and commands can now fl ow through user defi ned routing, adding Multi-Path capability, to avoid obstacles or equipment problems such as a broken cable. To further support this approach, buffering within the network allows data to be re-transmitted until it has been successfully received through either radio or cable sections of the network. Furthermore when the terrain of operations is not favorable to the deployment of cables; when rivers, canyons or large roads are real obstacles to the productivity of operations, the 408UL offers other solutions to transmit data and bypass these obstacles. Radio transmission, with the Line Repeater Unit (LRU) or laser transmission with the Laser Link can be setup and link together two portions of a spread cut by an obstacle. 8

7 408UL powerful software Specifically designed to maximize the performance potential of the 408UL The 408UL software offers highly effi cient single component or multi-component 3-D or 4-D recording and improved Quality Assurance and troubleshooting methods to address the huge volumes of data encountered in large full wave fi eld surveys. In order to accomplish this, Sercel 408UL software has been designed to work through a distributed architecture. We call this software Seismic Network Software. In this architecture the software not only exists in the recording node but is also distributed throughout the entire Seismic Areal Network. This structure allows the implementation of our new telemetry approach and the resultant fl exibility in operation of the Sercel 408UL. While the capability of the system has been changed we have maintained a consistent philosophy in our software as well as maintaining the Sercel look and feel. In this way we can help to minimize the amount of retraining necessary for personnel already familiar with the Sercel SN388. Enables the Seismic Areal Network Improved troubleshooting Supports channel numbering with ground coordinates to handle complicated spread layouts Constant, real-time Quality Assurance with esqc-pro Consistent user interface to reduce training.

8 Reliability beyond expectations... Extending our reputation for the highest reliability in the industry Throughout our long history we have developed a reputation for the highest reliability in the industry. With the 408UL we have increased this reputation for reliability still further: Fewer components Lower power Simple battery management Uncomplicated 4-wire cables No take-outs Fewer connectors Improved spread troubleshooting capability
