Our booth at the 79th Conference & Exhibition EAGE (photo report)
June 12-15, 2017
At this time, all new technology implementation, seismic data processing and interpretation projects are being operated by NPP Spetsgeofizika, founded in 2007. GDS retains its role as a petroleum geology consultancy and purveyor of innovative technologies.
Vibrators group management sequence:
To support thease objectives GDS-I® is equiped with modern radio and navigation devices.
The control system uses the following radio devices:
Radio modems provide radio net between the Encoder and Decoders through Radio.
Three types of data transmitting are supported::
The control system allows working in poor radio signal conditions (signal/noise 10 – 20 dB depending on the transmission speed). The radio transmitted PSS data are at the same time recorded to the Decoder NVRAM and can be read later over the radio or cable.
Local Net is based on the built-in transceivers of the license-free range of 433-434 MHz.
Local Net provides:
Vibrators from different groups can use various frequency subranges
The control system can use built-in GPS/GLONASS receivers (JAVAD JNS 100-GG) or any other external ones working under the NMEA protocol.
In the DGPS mode, correction transmission is provided through:
When the vibrator is moving, the name of the nearest source point (SP), the distance from the SP to the vibrator, and the distance from the vibrator to the nearest center of gravity are shown on the display.
