Towed HRStreamer for high resolution and ultra-high resolution marine seismi

Product code : 1753088316

Suitable for all types of HR/UHR surveys Supports optimal towing depth, slanted cable and deep tow acquisitions High sensitive hydrophones, protected from acceleration noise AVO friendly Custom configurations available 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.
