RESERVOIR PRESSURE MAINTENANCE (RPM) ON OIL DEPOSITS

Abstract

The article provides a brief analysis of the issue of improving oil recovery as a result of lower formation pressure in offshore oil wells. In the introductory part, the issues of lowering the formation pressure during the operation of oil and gas fields were considered. It is known that during the initial operation of wells, the wellhead pressure is high, so the wellhead is sufficient to transport pressure. However, after a period of operation, a sharp drop in formation pressure is observed, and when the wellhead pressure is less than the pressure in the in-house pipelines, it is not possible to transport the oil or gas obtained through these pipelines. In such conditions, in order to improve the development of oil storage, products from offshore oil and gas fields are transported to the shore through special tanks. The issue of increasing the wellhead pressure of such wells has been widely studied, as the occurrence of such transport leads to the consumption of additional funds. The decrease in formation pressure is observed differently in different wells. This situation mainly varies depending on the operating conditions and service life of the wells. In this case, in order to increase the service life of oil and gas fields, work is underway to artificially increase the formation pressure. Thus, in order to eliminate the problem of reducing the formation pressure, gas or liquid is injected into the well from the outside, which helps to increase the pressure. In wells where the pressure in the pipe mouth space is reduced, the process of applying additional pressure from the outside is carried out continuously during the next operation. Then the pumps used to inject liquid and gas into the reservoir were inspected. Their equipment and various parts are shown through graphs. It was noted that pumps and pumping equipment differ in their characteristics depending on the volume and conditions of liquids and gases injected from the outside as a result of the reduction of formation pressure. In addition, the collection system and transportation process of such wells have been reviewed and explained in detail using graphs and tables. Finally, the generalized results from the considered topic were noted.
