WirelessSEISMIC RT System 2
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.
Major advantages of SCOUT wireless seismic recording system:
Unlimited number of channels
Automatic positioning on seismic line
Wireless data acceptance w/o retrieval of the field unit from seismic line
Real-time layout parameter control and that of each field unit
32 GB built-in memory
Up to 25 days of continuous operation due to the built-in battery
Operation in environments beyond the reach of cable networks
Connection for external geophone pattern of various configuration
Operation using three-component geophones (single- and three-channel version (setup) of field units)
Wireless power switch;
Tough hermetic housing (case)
Special built-in battery charging system
Possibility of combined layout using any cable networks
Continuous oil&gasfield monitoring.
Output SEG-D and SEG-Y file composition
Interconnection of external battery for off-line operation time increment
Module-type readout system via Ethernet (readout speed – up to 1 Gb/s)
LED indication of technical state of the field units
Operating temperature range - 40 through +70 °С;
Operation with explosive, impulsive and vibratory sources
High mobility system (light weight and small dimensions)
Automatic recorded data transmission from seismic line to the station upon entering station-mounted Wi-Fi access point coverage zone (distance – up to 1 km)
Operation within freak GPS range
Enhanced system reliability (exposure protection, including static-discharge protection)
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.
