The PU has experience in working both on land and in transit zones. In recent years, the focus of work has shifted towards marine work. The PU has modern equipment and is equipped with the necessary technical means to perform work in transit zones.

The production department of JSC «GEOTEK» in Astrakhan has modern equipment and is equipped with the necessary technical means to perform work in transit zones and successfully copes with the tasks set for seismic exploration work in the waters of the seas.

Seismic exploration using 2D and 3D technology on land and in the transit zone using the following types of sources:

• · explosive;
• · vibration;
• · pulse;
• · pneumatic.

Related research methods:

• · vertical seismic profiling (VSP);
• · study of the upper part of the section (UPS) and low-velocity zones (LVZ) by microseismic logging (MSL) and refractive wave method (RWM);
• · magnetic exploration, electrical exploration, gravity exploration;
• · airborne laser scanning (ALS).

Use of highly productive systems:

• · Flip-Flop —excitation of elastic vibrations is performed by signal sources alternately;
• · Slip-Sweep —signal sources operate simultaneously;
• · wireless seismic exploration — Seismic data are collected and recorded via radio or stored on memory devices inside the blocks and then read via Wi-Fi or when collecting all recording blocks of the NODE type.

Data quality control.
