rt_sys2.jpg

•The only available today cableless seismic recording system providing   real-time data quality control.
•Combines all advantages of cabled and cableless systems.
 
MAJOR ADVANTAGES:
•System compactability and reliability
•Operating in areas where cabled systems cannot be used
•Unit location automatic positioning mode
•Real-time layout parameters control and that of each field unit
•Real time data transmission or recording to the built-in memory (4 GB)
•Up to 22 days continuous battery operation
•Any external group of geophones connection
•Roughneckproof and sealed case (IP67)
 
 

MUSTER SERVICES LTD employs SCOUT wireless telemetric system in the capacity of commutation device (seismic recording system).

SCOUT is a wireless telemetric seismic recording system intended for executing the wide range of projects: engineering surveys (min. quantizing interval – 0.25 ms), survey of the upper part of profile, 2D projects, 3D projects with unlimited number of channels, 3C projects (operation using three-component sensors), 4D projects (oil&gasfield survey, monitoring while drilling). Due to the absence of cables and availability of wireless interfaces SCOUT makes it possible to arrange the flexible scheme of project implementation, spare financial assets by reducing logistics costs and expenses, enhance work performance.

                                   MUSTER Service LTD makes use of  GS-One pickup geophones designed by Geospace Technologies company to record elastic vibrations.   

 

The new GS-One, single-element geophone is designed in such a way as to be comparable in sensitivity with seismic geophones of 3 х 2 or 6 x 1 pattern, resulting in price, weight and compactness gain. It features low-distortion level, high “signal/noise" ratio and reliable quality signal. The sensitivity rate enhanced to more than 2 V/in/s turns this single-element unit into the hi-tech device fully compatible with the state-of-art 24-bit systems which are capable of recording extended amplitude range offered by this pick-up.
