GeoEel-Liquid

The GEOEEL series of digital towed hydrophone streamers are the first small diameter arrays with the performance of larger systems. With a diameter of only 41mm, the GEOEEL-Liquid is easy to deploy, easy to transport and largely immune from the noise, leakage and ground loops that plague the installation of analog streamers in a marine environment.

The GEOEEL-Liquid is filled with inert silicon oil which makes it environmentally safe. Thick 1/8" abrasion resistant polyurethane keeps the streamer extremely rugged but still flexible enough to deploy by hand or mount on small winches. And the GEOEEL-Liquid is easy to repair – no fragile fiber optics to break or go bad.

Sampling intervals of 2 ms to 1/8 ms make the GEOEEL-Liquid suitable for deep petroleum, high-resolution engineering surveys or even sub-bottom profiling. Near-zero dead time makes surveys fast and efficient. A built-in digitally controlled oscillator provides calibration test signals for each channel. Other tests include noise, offset, pulse test, timing, leakage and capacitance of hydrophone elements.

The GEOEEL-Liquid transmits data via fast Ethernet to Geometrics CNT-1 controller, running field-proven software that is used on over 40 vessels today. And the GEOEEL-Liquid is entirely built by Geometrics, known for over 30 years as an industry leader in rugged, reliable and well-supported instrumentation.
