Equipment

Our crews use the latest seismic technology and are capable of operating in all terrains. We also have extensive experience of transferring equipment from Russia to other geographies.

The type of equipment used to acquire seismic data has a direct effect on the quality of seismic data ultimately obtained. Therefore, each of our field crews carries the specific equipment necessary for different types of data acquisition. This typically consists of three principal categories: seismic signal sources (such as explosive, vibration, electromagnetic or high pressure pulse), a grid of geophones and a recording system.

The equipment required varies from region to region and is dependent on the survey area’s surface and geological conditions. For example, due to the significant forestation of Western and Eastern Siberia, the use of vibration signal sources is limited there. Therefore, we rely on explosive sources in approximately 70% of our projects undertaken in these areas.

We utilize the US manufactured Input/Output and ION seismic systems, the French manufactured SERCEL and some other Russian providers. However, the choice of which signal source manufacturer to use hinges on the brand of the data recording system used by the relevant crew.

With this in mind, a significant number of our vibration sources are manufactured by SERCEL – as it complements our choice of SERCEL data recording systems. By eliminating the need for the special adjustment procedures necessary for cross-brand set-ups, the efficiency of our operations is increased.

IGSS operates a large fleet of support ground vehicles and machinery, including tractors, trucks, bulldozers, off-road vehicles and snow-mobiles. In addition, we run a fleet of specialized exploration support and transportation units specifically designed for use in transition zones.

Fleet

We operate a fleet of approximately 3,500 support ground vehicles and machinery. This includes tractors, trucks, bulldozers, off-road vehicles and snow-mobiles. We also utilise a fleet of specialised exploration support and transportation units, specifically designed for use in transition zones.

Operational bases

The field crews are supported by 28 operational bases, located in each Russian hydrocarbon province where we operate – as well as Kazakhstan. 16 of these bases have specialized repair and maintenance centers which service our transport, machinery and equipment. They also calibrate the tools and conduct training for our engineers.

Cutting-edge technology

At IGSS, we are always looking for the next innovation. This means continually monitoring opportunities to implement new technologies and optimize our processes.

Historically, we have implemented a number of advanced technologies, enabling the company to enhance the geologic interpretation of seismic images. Vertical seismic profiling (VSP) is one example – an innovation which provides additional accuracy in measuring seismic velocity values at exact depth intervals beneath a site.

Currently, we are testing the use of a wireless high-speed data transmission system – a cutting-edge piece of technology which connects our on-site equipment with the recording system. Being wireless, it cuts out the need to unreel and lay cabling. This saves time and labor, while providing valuable flexibility when working in complex terrains and challenging environments.

Other recent innovations include three-component digital telemetry equipment produced by SERCEL which improves the quality of acquired data and adaptive seismic 2D/3D technology which allows for controlled modification of the linear sweep based on vibration feedback – improving the stability and reliability of seismic signals.

Finally, we have also implemented new technologies for transition zones during a recently completed 3D project in the Caspian Sea – named ‘Zykh and Govsany Oilfield’ – we were able to seamlessly record data in the ‘land-sea’ transition zone using a single recording placement. This was achieved by using an efficient combination of the four types of sources we believe to be optimal for each of the relevant landscape zones: vibration, pulse, explosives and air-guns.
