Research on the Efficiency of Oil and Gas Well Monitoring Systems

Nikolaienko, Y.S.

The master's thesis is dedicated to a comprehensive analysis of modern methods and technologies for monitoring oil and gas wells, assessing their efficiency, and formulating an optimal approach to well condition control under real geological and technological conditions of hydrocarbon fields.
The first section provides an overview of modern monitoring systems, including telemetric systems (SCADA), hydrodynamic and geophysical research methods, production logging, temperature logging, as well as electric and radiometric logging methods. Particular attention is paid to the role of tracer studies in establishing hydrodynamic connections between wells and assessing the efficiency of waterflooding.
The second section is devoted to the analysis of the real-world conditions of a specific field. The geological and physical characteristics of a carbonate cavernous-fractured reservoir are considered, the production characteristics of the wells and their performance indicators are evaluated. An analysis of the operation of SCADA in mechanized (artificial lift), flowing, injection, and observation wells is conducted.
The third section formulates the concept of an optimal telemetric monitoring system, develops an algorithm for conducting well testing based on SCADA data, presents the structure of the monitoring database, and outlines the principles for integrating the system into the overall field development management scheme. The software, interpretation tools, and opportunities for automating decision-making processes are analyzed.
