Hydromechanical release device (GOU)
Назначение:
Purpose
The GO is intended for uncoupling tubing pipes above the layout of the control panel in case of emergency or scheduled work. The device is used during drilling and blasting operations in vertical and inclined wells filled with oil, water or other flushing liquids.

Advantages and opportunities:
Initiated by GO (ball)
If necessary, the ball is not dropped into the face, after which the perforation system is removed from the well.
In the opposite case, after dropping the ball, the punch system is reset. In the future, a geophysical study of wells or (and) hydraulic fracturing is possible.
