HRStreamer is an easy-to-operate seismic streamer, which perfectly suits for basic UHR/HR marine seismic surveys.

HRStreamer is protected from acceleration noises and allows to receive broadband signal in 10-10000Hz frequency range, which ensures registering the signal from UHR sources without any high frequency energy loses.

Main advantage of the streamer is it its flexibilty in terms of group adjustment. We designed unique streamer, which can be applied for wider depth range without lose of resolution comparing to traditional single-channel streamers.

We use 4 groups with variable length, starting from the pure single hydrophone group and ending up with 48 hydrophones per group. These groups receive signal separately and can be used on its own or/and stacked together to increase signal-to-noise ratio.

Single channel HRStreamer can be easily placed on a small boat and deployed/retrieved by a single person.

Key features:
  • Wide depth range application due to variable length of hydrophone groups
  • Broadband signal registration: 10-10000 Hz
  • Towed buoys with positioning system
  • Noise acceleration protection
  • Environmental and shipping friendly (non-flammable filler)
  • Can be used with any HR/UHR source (sparker, boomer)
  • Easy to operate and maintenance
