... energy source during operations of winding / unwinding the cable.
The set includes:
Reel with high-voltage slip ring
Wire to connect a reel and a energy source
An example of the CST on P-waves field data obtained using the Pulse sparker, energy source Jack, and a hydrophone cable connected to ELLISS-3 seismic station:
above – CSP seismograms for two shot points; below – amplitude spectra of signal and noise recorded before first arrivals
Example of raw CST field data for operations with ...
... super-ultra-high-resolution / super-high-resolution (SUHR / SHR). The operation of the sources is provided by energy sources of the MultiJack series.
Due to specialized containers filled with multi-electrode groups, FWS sources allow operation on freshwater reservoirs. Sparkers SWS are the sources of open type with a number of electrodes in groups varying from 50 to 1000 pcs. The DWS series is equipped with a removable container and is designed for realization of shootings with buried systems.
As one wishes, it is possible to manufacture ...

Example of the сrosshole seismic testing field data and its spectral composition (blue – for the entire wave pattern, green – for the first break, brown – for noise before the target waves arrival).
Data obtained with borehole sparker Pulse, energy source Jack-2500HP and hydrophone array WellStreamer.
Crosshole seismic testing field data obtained with borehole sparker Pulse, energy source Jack-2500HP and hydrophone array WellStreamer.
The distance between the central and lateral wells - 30 m.
High charge rate
Flip-flop, simultaneous source, code sequences and multilevel sources support
Energy sources MultiJack provide operation of
sound sources that are used in geophysical surveys in the water area with Continuous Seismoacoustic Profiling (СSP), High Resolution or Ultra High Resolution Seismics (HRS/UHRS) and VSP.
In addition to supporting the standard mode of operation with a single ...
Capability of grouping
High pulse frequency
Operation in sea and fresh water
Stainless steel frame
Aquatory electrodynamic sources G-Boomer with a towed deployment device are designed to excite an ultra-high-frequency seismic pulse during detailed seismoacoustic studies in water areas. Unlike the sparker, boomer does not contain electrodes that are subject to wearing and can also work in both sea and fresh water. Electrodynamic excitation principle provides an exceptionally stable pulse with frequencies of 2-4 kHz, and the capability of grouping ...
The source generates a shear wave through an asymmetric blow delivered into wall of the well. A rigid pneumo-electric line makes it easy to rotate the source in the borehole, providing generation of “right” and “left” blows. The SHock source allows excitation of a seismic signal in both water-filled and dry wells, which is not feasible for borehole sparkers.
SHock is supplied on a reel equipped with a high-voltage slip ring. Thus, one does not need to disconnect the energy source during operations of winding / unwinding the cable.
The standard set consists of:
RT-3R reel is designed for the operation with
borehole sparker Pulse
. It is equipped with specially developed high-voltage slip ring that makes possible the high-voltage energy source while winding and unwinding the cable. Frames are made of lightweight and durable titanium alloy, the drum is made of aluminum alloy. The reel is equipped with ergonomic folding rotary handle. The reel frame has both special holder of the Pulse ...
SDW deck winches for high-voltage cable line of a source (sparker) are designed for temporary or stationary setup on sea vessels in order to provide hoisting operations and towing seismic sources during geophysical surveys in the water area. The winch is equipped with a high-voltage slip ring and water-resistant ...
