The technology of packer perforation followed by hydraulic fracturing or well logging
Download
Operating principle
Running the assembly with a packer, logging and perforating system on tubing. Next - setting the packer in the required interval. Activation of the initiating head, perforation with automatic release of the perforation assembly to the bottom with the option of subsequent well logging and (or) hydraulic fracturing.
Advantages
- Reducing the time spent for well development (at least 2 days)
- Saving well-killing fluid with high specific weight.
- Making a logging interval that is not clogged with well-killing fluid, without using additional resources of the well workover team to lift the tubing.

The packer perforation technique followed by hydraulic fracturing or well logging saves time and resources during the development of hydrocarbon fields.
The assembly with a packer and a perforation system is run on tubing. Then the packer is installed in a target interval. Next, the initiating head is activated and perforation is performed with automatic release of the perforating elements to the wellbottom. After that, it is possible to conduct geophysical surveys and/or hydraulic fracturing.
Advantages of the packer perforation:
- well development time is reduced (by at least 48 hours);
- the consumption of the well-killing fluid is reduced;
- it is possible to work without the involvement of a well workover team.
Secondary drilling of the formation, hydraulic fracturing and geophysical surveys are performed in one round-trip operation with subsequent release of perforation systems into the well without the need for subsequent killing.
