Geophysical Researches IN THE OPEN WELL OF WELLS

GIRS in the open wellbore. Tasks to be solved:

• Lithological and stratigraphic section of a well section;
• Isolation of collectors;
• Quantitative determination of reservoir properties of reservoirs;
• Determining the nature of saturation of reservoirs;
• Determination of the position of GNK, VNK;
• Monitoring wiring and determining the spatial position of the wellbore.

Technologies for the delivery of downhole equipment during the GIRS in an open wellbore (sidetracks):

• standard logging cable - vertical, directional;
• rigid geophysical cable (ZhGK) - directional, horizontal;
• technological complex "Lateral" - directional, horizontal;
• drill pipes - directional, horizontal.
