428XL is the most popular land seismic acquisition system with a proven performance and reliability. Extremely versatile, it can integrate any sensor type (analog or digital, 1-C or 3-C) and can be used in all survey conditions (arctic, desert, marsh zoneā¦). Leading the market, the 428XL is the system of reference in the industry.
BEST OWNERSHIP VALUE COMPATIBLE WITH UNITE – Benefiting from a very long and vast field experience with more than 5.000.000 channels delivered, 428XL is the reference acquisition system of the industry. Owners of the 428XL will accrue this benefit in the form of a five-year warranty on 428XL Line electronics, the longest in the industry. In case there should ever be a problem with field electronics, Sercel has revamped its customer service to replace covered equipment with a standard exchange instead of repairing any individual piece of equipment. Our customers will have more of their equipment working for them a greater percentage of the time than owners of any other systems
COMPATIBLE WITH UNITE – The Unite cable-free system can now integrate with the Sercel 428XL to act as a single system in some of the toughest environments in the world. UNITE boxes can be linked directly to the 428XL cable network in order to send data and conduct QC in real time. In autonomous mode, harvested data can also be sent directly into the 428XL line enabling immediate data reception by the recording truck. This unique product compatibility allows the use of a mix of cable and cable-free systems, opening up exciting new possibilities.
FULL RANGE OF SENSORS :
DSU1: 1-C Digital Sensor The DSU1 is a MEMS based digital sensor that receives seismic data in one component(1). The use of digital single sensors offers many advantages compared to an array of conventional phones. Single sensors avoid intra-array statics and with broadband linear response (DC to 800 Hz) and low distortion can provide the highest resolution data available. The small package of the sensor and low power requirements result in a very light weight solution compared with analog phones. (1) patents US 7,797,998 & US 7,552,638
DSU3: 3-C Digital Sensor The DSU3 is an integrated package made up of station electronics and three digital accelerometers based on MEMS (Micro-machined Electro-Mechanical Sensor) technology with low power consumption and full functionality at any tilt angle. The DSU has proven to be high-performance, powerefficient and reliable in all operations. The DSU3 digitizes data from a single ground station and its three orthogonal components allow it to accurately record the ground motion on all three axes. This is a significant improvement over traditional analog P-wave geophones that only record the vertical component. Utilization of the full seismic wave field, when accurately recorded and processed, enhances the seismic interpretation and reservoir characterization to help reduce F & D costs.
HIGH SPEED BACKBONE – A new range of equipment is now available for the 428XL system increasing the data transmission rate on the transverse from 100Mb/s to 1Gb/s. The capacity of this new transverse is thus also upgraded from 10,000 channels to 100,000 channels @ 2 ms in real time. For mega crews, the number of transverses and LCI will be divided by up to 10, simplifying the deployment and the recorder moves.
