GeoEel

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 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 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 is easy to repair – no fragile fiber optics to break or go bad.

Sampling intervals of 4 ms to 1/16 ms make the GEOEEL 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 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 is entirely built by Geometrics, known for over 30 years as an industry leader in rugged, reliable and well-supported instrumentation.
