Как работает технология
How technology works
Placement stations on the site
The vessel places the stations on the bottom of the GPS coordinates at regular intervals along the lines that form a flat two-dimensional grid. The exact location of each station at the bottom is determined by the acoustic channel.
Pneumatic source application, seismic data registration by stations
The source vessel runs along marked lines. Bottom stations record direct and reflected waves from the internal layers of the medium, generated by the source.
Start lifting stations
An acoustic signal is sent from the vessel to the ascent of a given station. Each station has its own ascent code. Further, the station with the help of special ejector, eliminating the jam at the bottom, is disconnected from the eco-anchor and floats. The ascent of bottom stations is carried out sequentially at regular intervals.
A GPS transmitter is installed at each station to determine its location on the surface of the water. At night, the lamp is turned on at the station for its prompt detection.
Lifting stations on board automated equipment
Bottom stations climb aboard the vessel with the help of special equipment, which allows to significantly speed up the production of works.
Wireless data copying
Stations are delivered to the terminal where the collected data is copied to the server over a high-speed wireless channel. Data acquisition occurs simultaneously using two technologies:
- 3D / 4C bottom reflection seismic;
- Direct searches for hydrocarbons by the low-frequency component of the wave seismic field.
Mounting eco-anchors to stations, placement in a new section
The lifting of the stations on the ship and the new arrangement takes minimal time, since there is no need to put on / remove the rope, reprogram and install into the service rack, which distinguishes us from the competitors. A large park of stations ensures the continuity of the work of the folding ship
