It is designed to determine bed slope angles and bed dip azimuth, rock stratification and fracturing in oil/gas, core-parameter and engineering-geological wells including inclined horizontal wells.

The dipmeter is used with any-type logging stations which are equipped with any three-core armored cable.

Featues and advantages

  • Large radial depth of focused circumferential scanning sounding of the near-borehole space;
  • High reliability of bed elements measurements, of fractures and other planes of rock anisotropy both in vertical wells and in inclined horizontal ones;
  • Identifying of sub-vertical and vertical fractures including the fractures which do not cross the bore hole; and of picking out of co-ordinates of their spatial orientation within the near-borehole space of up to 1 m in diameter.
