The subject of the study is oil fields of the Perm region, which is one of the oldest regions of hydrocarbon production in Russia. On the example of the largest Oil Company of the Perm region, LUKOIL–PERM LLC, the increase factors analysis of oil production for the period 2005–2019 for the specified formation was carried out.

The purpose of the work was to identify fields in Kashirskian-Vereiskian oil and gas formation, which are characterized by an increase of oil production in 2005–2019, and to rank by the increase in production. As a result, the main factors of production increase are noted on the example of the main fields.

The role of development technologies it noted, due to which it was possible to bring into production previously poorly drained or non-drained reserves. A number of factors that contributed to the forming of complex solutions to improve the development due to the large-scale application of geological and technical actions related to geological conditions and available technical capabilities that provide cost-effective results are indicated.

During the analysis, authors were based on previously performed work of the defining of 6 time periods, which are typical for oil production history in the Perm region in 1939–2019, and results and conclusions that were obtained in another oil and gas reservoirs of the Perm region.

The results presented in the article are the next step in generalizing the experience of field development aimed at a detailed search and analysis of the oil production increase causes in the Perm region.

The authors plan to consider the following topics in more detail in the future: The use of complex design wells on the fields of the Perm region as a factor of increasing oil production; bringing into development the new fields since early 2000s and their impact on the total oil production.
