PIPELINES AND HORIZONTAL DIRECTIONAL DRILLING<\/h1>\n

Geophysical surveys are commonly conducted for the diagnosis of the ground for the new, projected pipelines and for directional drilling HDD as-well (Horizontal Directional Drilling). This technology enables a significant reduction in length of the route e.g. Gas pipeline due to bypass the vertical obstacles such as rivers or water channels. Due to the fact that in the soil, where will be constructed new pipe \/ drilling HDD, there may be objects (e.g. Erratics) or be hostile geological formations that could affect the location of the projected route or even damage the equipment drilling. It is very important to accurate recognize the HDD drilling or pipeline route. Specialized geophysical and geological surveys, despite additional costs, allow to optimize and reduce the risk of hardware failure as-well reduce other unexpected costs.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

ADVANTAGES AND APPLICATION OF GEOPHYSICS FOR THE IMPLEMENTATION DIRECTIONAL DRILLING HDD<\/h2>\n
    \n
  • NDT (non-destructive)<\/strong>,<\/li>\n
  • continuously recognition of the medium<\/strong>, high accuracy survey and speed of measurements,<\/li>\n
  • the relatively low cost of the survey compared with the potential costs of drilling equipment repair,<\/li>\n
  • the possibility of measurements in different terrain and weather conditions,<\/li>\n
  • frequently the initial location of the underground objects in the field,<\/li>\n
  • the location of unidentified objects in the ground eg. rocks, tanks, foundations,<\/li>\n
  • determining the occurrence of lithological layers, eg. clay, sand, gravel,<\/li>\n
  • determining the location and shape of the hard soil ceiling.<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
