Main pipelines, oil and gas

Near-surface geophysics for main pipelines and oil and gas infrastructure facilities

Engineering-geological surveys along oil and gas pipeline routes and at well cluster sites:

• identification of high-ice rocks
• study of taliks, cryopegs
• study of the dynamics of permafrost phenomena (seasonal freezing zones)
• identification of geological bodies that are dangerous during drilling (vein, formation ice)
• bedrock roof mapping
• determining the level of groundwater and the presence of perched water
• identification of zones of distribution of specific soils (peat, silt, saline soil, etc.)
• identifying gas pockets in the upper part of the cut
• assessment of reserves of construction materials in quarries
• study of dangerous engineering-geological processes (landslides, quicksand, karst phenomena)
• study of the engineering and geological situation of territories adjacent to oil and gas industry facilities
• study of the velocity characteristics of the upper part of the section for 2-3D seismic exploration
• geoecological surveys of oil industry enterprises
• conducting reconnaissance technological studies in oil and gas fields
