Aerodynamic body with carbon fiber frame weighs only 1.3 kg with battery. The low weight increases the flight time of the drone. The magnetometer requires no data exchange with the UAV and uses its own battery, so it can be used with any UAV.

Land Seismic Equipment

Geophysical Survey Seismograph

The Sigma 4+ is a compact 4-channel seismograph tailored for versatile geophysical survey requirements. It features a high-frequency sigma-delta analog-to-digital converter (ADC) and is equipped with a GNSS receiver, providing flexibility for geolocation and synchronization. The device offers continuous recording capabilities and supports multiple configurations, including external 2 Hz 3C geophones, hydrophone streamers, and other seismic sensors. The system operates with a broad sampling rate range up to 64,000 Hz and exhibits a dynamic range of 127 dB. It includes features for digital filtering and noise reduction, ensuring precise data collection in various environments. Designed for rugged use, it can operate across a wide temperature range and withstand harsh conditions. The Sigma 4+ is also well-suited for various applications, such as seismic monitoring during pile length testing, seismic surveys in urban settings, and high-resolution marine seismic acquisition. It supports standard data formats like SEG-Y, making it compatible with existing data processing workflows.

High Resolution Seismic Recording System

DAQlink-5 is a portable inline seismic seismograph that provides seismic surveys with any methods on land, in boreholes and in the water area. The possibility of continuous data recording allows using the seismograph as a stand-alone recording system for seismic monitoring or passive MASW. The number of channels in one recorder could be 6, 12, 24 or 48, but the system configuration allows increasing their number by linking the seismographs through cable lines up to 3 km long, which are used for time synchronization in the modules and data exchange between them. When using the seismograph as a stand-alone recorder, time synchronization of the units is carried out through a GPS receiver, and in the case of operation in mines and tunnels it is maintained through a built-in clock or with the help of a VHF radio modem.

Borehole Seismic Equipment

Geodevice - Energy Source for Seismic Testing and Tomography

Jacks are the lightest, most compact, and fastest energy sources in the world that ensure the operation of borehole sparker and electrodynamic sources used in geophysical surveys including cross-hole seismic testing (ASTM D4428/D4428M) and tomography (CST), high-resolution VSP, and reverse VSP or vertical seismoacoustic profiling (VSaP). Our convenient and intuitive Jack control panel allows flexibility in configuring the shooting mode. It is easy to program the cycle with the required number of shots and the period between them, the required energy and power consumption, as well as triggering from a seismic station or a synchronization system. Remote control unit JackPad duplicates the control panel and allows the seismic station operator to fully control the entire system. It is important to say that JackPad also provides additional safety of work.

Geodevice - Borehole Sparker for High Frequency Seismic Surveys

The Borehole Sparker Pulse is a specialized tool designed for generating high-frequency pressure waves in water-filled wells, with applications in crosshole seismic testing, vertical seismic profiling, and other geological survey techniques. It utilizes a pulsed power supply to create ionized cavities that efficiently generate seismic pulses. The system includes special electrodes that ensure long-term stability and performance. It accommodates borehole depths up to 1000 meters and is adaptable to different depths with cable options ranging from 50 to 500 meters. The design allows easy replacement of electrode groups, and specific configurations can enhance signal-to-noise ratios. The sparker is available on reels with high-voltage slip rings, and its construction includes reinforced polyurethane insulation to ensure durability under demanding geological conditions. Safety and ease of operation in deep wells are enhanced with specialized winches. Customizations are available for specific requirements, underscoring its versatility and application in advanced seismic survey techniques.

Geodevice - SHock Borehole Seismic Source

SHock is a specialized borehole seismic source engineered for the generation of horizontally polarized Shear Waves (SH) and Compressional Waves (P) suitable for techniques like reversed Vertical Seismic Profiling (VSP) and Crosshole Seismic Testing (CST). It features simplicity in operation and a high level of repeatability, making it ideal for both dry and water-filled boreholes when coupled with the energy lever Jack. This system operates on a pneumo-electric line allowing precise source rotation within the borehole, enhancing the signal-to-noise ratio by facilitating opposite SH-wave polarization detection. Its electrodynamic mechanism generates high-frequency energy pulses, critical for detailed seismic data captures that facilitate accurate first break picking and refined VSP seismic sections. This seismic source comes with an integrated high-voltage slip ring and pneumatic fitting which streamlines the data acquisition process without disconnection during cable winding. SHock operates with a voltage up to 6000 V and energy up to 1500 J.
