Microprocessor System of Initiation
Download
Application
Provides for remote initiation of a perforating system and recording of well parameters before, during and after the initiation. Allows to perform selective perforation in one run.

Advantages:
- separate initiation of two (or more) devices running simultaneously reduces the number of runs;
- the possibility to set an individual initiation delay for each MPSI head reduces the shock effect on the casing string;
- reduction of the cost of one hole due to the use of tubing pipes as passage sections instead of perforators with a detonating cord;
- reliability of operations under varying pressure and in all types of wells, including wells with complex profiles;
- no additional security measures required, except for the restrictions on the explosives used.
