Engineering geophysical surveys for oil and gas field

Constant improvement of methods of complex engineering geophysical surveys for oil and gas field makes it possible for GEOTECH to guarantee the gaining of reliable and high-precision data.
The application of a complex of electrical survey, seismic survey and GPR survey methods with own manufactured equipment enables the experts to obtain quite interesting and substantial research results.
The main applications:

• Engineering geological surveys
1. Geophysical surveys for oil and gas pipelines construction
2. Geophysical surveys on sites of cluster wells location
3. Detection of heavy icy rocks
4. Examination of taliks, supercooled water brines with permafrost
5. Examination of permafrost dynamics (seasonal freezing zones)
6. Examination of geophysical bodies associated with drilling hazards (vein, bedded ice)
7. Mapping of bedrock foundation roof
8. Determining occurrence level of subsoil waters and upgrade water existence
9. Locating zones of specific subsoil spread (peat, silt, salt subsoil etc.)
10. Detecting gas pockets in the profile upper part
11. Assessment of construction material reserves in open-cuts
• Study of dangerous engineering geological processes:
1. landslides
2. floating earth
3. karstic phenomena
• Study of engineering geological environment of the zones adjacent to objects of oil and gas branch
• Study of speed abilities of the profile upper part for 2-3 D seismic survey
• Geoecological survey of enterprises of oil branch
• Reconnaissance seismic surveys of oil and gas fields
