Slips explosive packer (SEP)

Назначение:

Purpose

VPS is used to install drilled separation bridges in fixed well intervals.

This equipment is used when it is required to separate productive formations in exploration wells, form an artificial bottom, isolate the formations from water, or cut off a certain perforation interval when examining the technical parameters of the column.

Advantages and opportunities:

it is possible to lower packers into wells on cable and tubing
the small outer diameter of the packers improves patency in the well
they are installed in the well regardless of the depth of the work being carried out
unification with other models of explosive devices
the possibility of liquidation by drilling
It has original design features that enhance the safety of restoration and repair activities.
