Increasing oil recovery in reservoirs is of critical importance for optimizing hydrocarbon production and sustainable development of the industry.

The relevance of enhanced oil recovery in reservoirs is due to several key factors. Firstly, global hydrocarbon reserves are gradually being depleted, which requires the development of new technologies and methods for the efficient extraction of oil residues from existing fields. Secondly, the modern development of production technologies, such as hydraulic fracturing, steam injection and improved oil recovery methods, can significantly increase the index of hydrocarbon recovery from reservoirs, thereby increasing the economic efficiency of projects.

Increasing oil production is one of the main tasks of the oil and gas industry aimed at maximizing the extraction of hydrocarbons from the reservoir. The development and implementation of various methods of increasing oil production can significantly increase the economic efficiency of using oil fields. There are many types of enhanced oil recovery. In this article, I have considered one of the most effective methods of increasing oil recovery – the thermal method, including steam cyclic well treatment (SWT). The steam-cyclical effect on the formation is an important aspect in hydrogeology and oil and gas drilling. This topic covers the influence of steam-cyclical processes on the migration of hydrocarbons, their accumulation and distribution in geological formations.

Steam cycling processes can affect rock permeability by determining how efficiently oil and gas can move through porous layers. This, in turn, affects the efficiency of hydrocarbon production.

As a result of research in this area, more accurate forecasts of hydrocarbon reserves and their extraction are becoming known, which is actively used in modern methods of field development.In addition, the features and advantages of the SWT process are discussed here.
