Borehole Seismic Survey Systems
HGS-Downhole 3C Unit
The Downhole 3C Geophone Unit is a specialized downhole and crosshole receiver designed to record seismic P-wave and S-wave travel times within boreholes, enabling detailed analysis of subsurface rock formations and sediment properties for geotechnical and geophysical investigations.
HGK3/HGK7 Borehole Geophone
The HGK series borehole geophone detects P- and S-waves in dry or water-filled boreholes using pneumatic clamping and multi-axis sensors with magnetic compass orientation.
HG-Downhole Source (DHS)
The Downhole Source is a specialized seismic source system. This instrument is designed for cross-hole surveys, a technique used to measure the subsurface seismic wave velocity between boreholes and is a crucial method in geotechnical and geophysical site investigations.
Borehole Deviation Probe
Deviation probes are used to measure borehole deviation and ensure accurate positioning of seismic sources and receivers, enabling precise borehole seismic measurements.
Energy Sources Jack
Jacks are lightweight, compact, and fast energy sources designed to operate borehole sparker and electrodynamic sources used in geophysical surveys such as cross-hole seismic testing and tomography (CST), high-resolution VSP, and reverse VSP or vertical seismoacoustic profiling (VSaP).
Borehole Sparker Pulse
Pulse is a borehole sparker source designed to generate high-frequency compressional (P) waves in water-filled wells up to 1000 m deep for applications such as crosshole seismic testing or tomography (CST), vertical seismic profiling (VSP), and other borehole seismic surveys
Borehole source of SH and P waves SHock
The SHock is a unique borehole seismic source designed to generate horizontally polarized shear waves (SH) and compressional waves (P) for applications such as reverse Vertical Seismic Profiling (VSP) and Crosshole Seismic Testing or Tomography (CST).
Borehole source of SV-waves GeoSV
GeoSV is a borehole electrodynamic source used to generate vertically polarized shear waves (SV) in dry or water-filled wells up to 200 m deep for parallel cross-hole seismic testing (CST).
Borehole Hydrophone Array WellStreamer
WellStreamer is a borehole hydrophone array designed for seismic data acquisition in water-filled wells. It features sensitive piezoceramic sensors with built-in preamplifiers to record compressional (P) waves during VSP, crosshole surveys, parallel seismic testing, and borehole seismic methods.
GStreamer - 3C Multi-Level Downhole Seismic Array with Spring Anchoring
GStreamer is designed for Vertical Seismic Profiling (VSP) and cross-hole seismic testing and tomography (CST) in boreholes with PVC casing.
GStreamer-E
GStreamer-E is a multi-level borehole 3-component (3C) seismic array equipped with a geared motor–driven anchor in each module. It is designed for applications such as Vertical Seismic Profiling (VSP), downhole seismic logging, and cross-hole seismic testing and tomography (CST).
GStreamer-P
GStreamer-P is designed for Vertical Seismic Profiling (VSP), downhole seismic logging, and cross-hole seismic testing and tomography (CST) in both open-hole and cased wells up to 1000 m deep. The system can be configured with 4 or 8 borehole 3-component (3C) tools mounted on a pneumoelectric cable line.
