Geophysical survey in the waters

1) High Resolution Seismic

Depth of method: up to 1000 m

Resolution: 2-4 m

Source: Air Gun

Receiving device: seismic streamer 100-300 m, the ability to work with a buried system

Tasks to be solved: Search and mapping of geological hazards (gas caps, faults, landslides, frozen rocks, etc.), analysis of the density properties of rocks, determination of the structural features of the section

Sample data:

2) Ultra High Resolution Seismic

Depth of method: up to 200 m

Resolution: 1-3 m

Source: electro-spark (“sparker”)

Receiving device: seismic streamer 32-60 m, the ability to work with a buried system

Tasks to be solved: Search and mapping of geological hazards (gas caps, faults, landslides, frozen rocks, etc.), analysis of the density properties of rocks

Sample data:

3) Ultra-high resolution seismic survey (NSAP, profilograph, VCh NSP)

Depth of method: up to 15 m

Resolution: 0.3-0.5 m

Source: piezoceramics

Tasks: a detailed study of the upper part of the section from 0 to 15 m, mapping of pipelines, finding places of damage to the upholstery of pipelines, searching for gas leaks, detecting and mapping near-surface objects, detecting gas caps in the upper part of the section, mapping landslide bodies

A parametric profilograph allows you to study the upper part of bottom sediments to a depth of up to several tens of meters (under favorable geological conditions) in areas with water depths of up to 400 meters. Suitable for both a detailed study of bottom sediments, and for mapping objects at the bottom

Sample data:

4) Sonar side view

Equipment: Klein 3000, Benthos C3D, StarFish F450

Tasks: mapping of geological objects and phenomena, detection of dangerous objects on the seabed, inspection of underwater parts of engineering structures

Sample data:

5) Multipath echo sounder

Multipath echo sounders are used to perform surveying work on large areas with high detail and continuous coverage of the bottom by shooting.

Tasks: search for objects at the bottom, search for gas bubbles in water, research of underwater engineering structures

Sample data:
