Seismic surveys
All-terrain seismic acquisition concept.
SN388 is the first in the family of Sercel SN seismic data acquisition systems with the reputation of the highest reliability, provision of total pre and post shot quality control of every aspect of the spread.
The SN388 architecture includes packages such as SQC-PRO that runs on an advanced UNIX Workstation directly interfaced to the SN388, Acquisition Processing Module (APM). SQC-PRO offers a powerful tool for real-time quality assurance and quality control of seismic data at the recording site along with the packages for on-line, real-time Vibrator Quality Control (VQC) processing. These provide the opportunity to check and adjust vibrators position and source single parameters.
For Vibroseis operations, the standard HCI software runs complete remote control of the VE416 or VE432 vibrator electronic parameters. During operations, the VE416 or VE432 vibrator status information is received in real-time for storage and Vibrator Quality Control (VQC) analysis.
SN388 can be configured with up to 16 - 1200 channel recording modules providing a total spread capacity of 19,200 channels at a 2ms sample rate, and maximum channel capacity expands to 38,400 at a 4ms sample rate.
The field recording units SN388 (SU1) are packaged into sealed, waterproof aluminium cast cases, and can operate in a temperature range from -40 °C to 70 °C.
A specially designed set of cables and connectors provides the optimal speed and flexibility for deployment and roll along as well as for moving around obstacles and changing terrain.
