2016

Beginning of development of the Perfobore vehicle

The first prototype of the equipment was developed. The production and technical center has started functioning

2017

Successful bench tests

To conduct bench tests, a special stand was created for drilling sand and cement blocks that correspond to the characteristics of the productive reservoir. A number of decisions were made to improve individual nodes of the Perfobore vehicle for greater performance and reliability

2018

First downhole tests

Based on the results of a series of field tests of the first-generation layout, it was proved that the concept of the Perfobore system was chosen correctly, and the calculated data converged with the actual ones. The team started developing a second-generation system that takes into account the accumulated experience. It was proposed to introduce new node materials and more promising technical solutions

2019

First commercial works

Work was successfully carried out on 5 wells. The first experience of working on a terrigenous reservoir in a gas well, a record increase in Qg +217 thousand m3/day was obtained. For the first time, hydrochloric-acid treatment was performed in drilled channels in a carbonate reservoir

2020

Commercial works

Work was successfully carried out on 5 wells. For the first time, the casing of drilled channels with slot filters in a terrigenous reservoir was carried out, the increase was Qn +100t/day

2021

Work was completed on 20 wells, development of new territories

Successful work has been carried out in new countries: the USA, Kazakhstan and Uzbekistan. Work was performed in a well with a depth of 4500 m.

2022

Work was completed on 25 wells

The 100th channel has been drilled. A layout for drilling channels with a length of 25 m has been developed and applied. The technology has been tested as an alternative to ZBS (side barrel cutting) and a finishing method. A record increase in the Qh +44t/day carbonate reservoir was obtained

2024

First work in open hole

Successful drilling channels from a horizontal wellbore
