The latest most significant development projects of Vega LLC
Magnetically Shielded Calibration Unit (MSCU)
Every specialist involved in accurate measurements of weak magnetic fields is familiar with the problem of using sensitive magnetometers in conditions of urban environment.
During the production and maintenance of precision induction magnetic sensors, the most efficient setup and calibration process for these complex instruments is required.
The Company’s engineers designed and manufactured a calibration unit with a multi-layer system of magnetic shields, which significantly reduces the level of external electromagnetic noise in a wide frequency range. With this facility, sensitive magnetic sensors can be set up and measured in almost any convenient location – in a laboratory, workshop or office building.
This facility significantly reduces the production and maintenance time of the IMS series sensors.

Magnetically Shielded Room (MSR)
Creating a space for physical measurements that is protected from magnetic interference is an important task not only in the production of magnetic sensors, but also in a wide range of different research tasks.
Experience in designing and calculating magnetic shields, as well as the need for a wide range of organizations to use magnetically shielded laboratories for their needs, led to the idea of designing a room that is completely shielded from any magnetic interference.
Employees of the Company, using the vast experience, gained in fulfilling the order of the Centre for Cognition and Decision making, Institute for Cognitive Neuroscience, HSE University, Russian Federation, for the installation and research of MSR characteristics, developed by the German Company Vacuumschmelze, began to create their own magnetically shielded rooms.
The Presentation of the first MSR in the Company’s office is planned for 2024.

Marine Magnetotelluric Station
One of the new research field actively developed in the modern geophysical industry is an offshore electrical exploration and, in particular, magnetotelluric method, which is recognized as promising for oil and gas exploration. Magnetotelluric or MT is one of the most popular non-seismic methods for studying the Earth’s crust.
Since 2009, the company has been developing equipment for conducting geophysical measurements on the shallow water shelf. For more than ten years of experience in the design of marine equipment, three versions of marine bottom magnetotelluric stations have been developed and manufactured as part of commercial order.
MMS-20. Depth up to 20 meters.
MMS-70. Depth up to 70 meters.
MMS-300. Depth up to 300 meters.
Advanced audiomagnetotelluric station VAMT-23
Audio-magnetotelluric or AMT is used to perform geophysical surveys in which the target depth of exploration is the first hundreds of meters. For this technique, a special type of magnetic sensor records EM field variations. Typically acquisition last for several tens of minutes.
Usually a broadband MT-station operating in AMT mode is used in such works. The task of developing a specialized AMT station that works only in audio frequency bands is considered appropriate and promising. Such a complete set of instruments seems to be more compact and cheaper to produce as well.
The new model of search coils IMS-003 has been specially developed for usage with VAMT-23.
Advanced complex for sounding using high-power single electromagnetic impact
The promising method of a high-power single electromagnetic impact can become an alternative to classical methods of electrical exploration. By generating a powerful single pulse and recording its response with MT or AMT set of stations, it is possible to achieve detail and depth of sensing compared to the traditional MT method, while using a controlled, rather than natural source.
The hardware and software complex for sounding the Earth’s crust using a powerful single impact method includes:
- Single impact powerful transmitter based on a 3-axle truck (developed and manufactured by ROSATOM State Corporation);
- Transmitting antenna (a loop);
- Observation network consisting of MT stations VMTU-10 or VAMT-23 (depending on the depth of research and geological conditions)
- Center for Reception and processing of field data (CRP);
- Processing software package.
Advantages of the new method:
- A regular monitoring network, created with the help of MT stations already developed by VEGA, will allow performing electrical exploration not in single point, but simultaneously on a large area of work.
- The controlled current source can be located with a given orientation of the radiating line relative to the possible configuration of the studied geological objects, which will increase the resolution of the method.
- The transmitter facility has a possibility to generate of 1 pulse in every 30 minutes, which allows you to adjust the parameters from the CRP during research and get results directly at the work site.
- The complex is mobile, high-performance, easy to maintain and can be used at any time of the year for conducting area electrical exploration.
Hydraulic fracturing monitoring system
Hydraulic fracturing (FRAC) is a promising method for developing oil fields. The method allows to extend the life of the oil field. It is widely used in the operation of oil and gas fields to increase the flow rate of wells. When planning hydraulic fracturing, it is very important to have information about the configuration of the fracture space, especially with multiple and directional hydraulic fracturing options.
Electromagnetic monitoring of crack propagation during hydraulic fracturing is based on changes in the electromagnetic properties of the medium in real time. Stations are arranged by area, and data acquisition systems are attached to the main head unit. A special program collects data simultaneously from all devices and analyzes the entropy of the electrical conductivity of the hydraulic fracturing site.
Fluxgate magnetometer
A fluxgate magnetometer is a compact sensor for measuring low-frequency magnetic fields. Unlike the IMS series of induction sensors, fluxgate magnetometer is designed for measuring large-scale magnetic field variations and can be used as a low-frequency sensor in MT-based work and other applications. At present, Vega’s engineers are developing a new fluxgate magnetometer of its own design to satisfy the needs of the Company.
