SAS-90 downhole acoustic scanner

CАС-90 allows for obtaining high resolution acoustic images of the well bore filled with water or oil-based drilling mud.

Images allow for determining bedding elements exposed by the well, for identifying fracture intervals and determining fracture quantitative characteristics (density, dip angle, strike azimuth). Interpretation of the obtained data provides very accurate characteristics of stress and drilling-caused phenomena, such as: inrush of well walls or formation of man-caused fractures, trenches, etc., the well section geometry is studied by intervals, providing confident conclusions as to the well bore stability.

Nuclear magnetic logging

It is based on measuring the signal issued by porous liquid (water, oil or gas) hydrogen nuclei free precession in the rock in the Earth magnetic field under well conditions.

The survey is conducted using YaK-8 instruments in the Earth natural field or nuclear magnetic tomographic logging in an artificial magnetic field created by a permanent magnet.
