Fiber Optics Reservoir Monitoring System Sustainability in Extreme Gas Well Conditions

Abstract

The purpose of this study is to illustrate how the long-term viability of fiber optic technology in conjunction with a Permanent Downhole Monitoring System can considerably endure the difficult conditions that are present in wells that are subjected to severe vibration and extreme pressure. The system ensures that defined target objectives are consistently delivered, which adds value to a large middle eastern National Oil Company (NOC). This is accomplished within the challenging conditions of gas production wells.

One of the most persistent challenges that arises during routine operations is the deployment of a downhole pressure and temperature gauge that is both dependable and sustainable in wells that are subject to high levels of pressure and vibration. Because of the intense vibrations and pressure that are exerted on the electronic components of a normal electronic downhole monitoring gauges, electronic systems that are deployed downhole are frequently prone to failure. With its ability to perform well under high-pressure, high-temperature, and high-vibration circumstances, the optical pressure and temperature (P&T) gauge system, in conjunction with Distributed Fiber Optic Sensing (DFOS), provides a solution that is reliable.

Optical P&T systems have been thoroughly integrated into a variety of field applications, and additional systems are planned to be deployed both onshore and offshore in the near future. After they have been installed, these technologies will transfer vital information in real time to the control room of the engineering team as well as to the teams responsible for reservoir management. Using fully developed fiber optic systems, which alleviate prevalent operational difficulties such as high vibration settings, harsh pressures, and extreme temperatures condition survivability, it is possible to guarantee reliable and superior data transmission even in challenging downhole conditions. This is made possible through the utilization of fiber optic systems. Through real-time data access and advanced analytics, which include well integrity acknowledgments, the inclusion of a monitoring system that is enabled with DFOS considerably improves the supply of crucial insights into the integrity of the well (Gang Tao, 2023). It is anticipated that the combination of DFOS and downhole monitoring gauges will result in long-term benefits. These benefits will be achieved through the enhancement of performance, the prediction of possible failures, and eventually the maximization of the well system's longevity and efficiency.

The integration of DFOS technology with downhole monitoring gauges results in the creation of a cutting-edge monitoring solution that generates data in real time on the dynamics of reservoirs under extreme conditions, such as those that are encountered during fracturing applications. The system is positioned as a new solution for proactive reservoir management as a result of these qualities. It provides novel chances for optimization and enhances operational decision-making to an extent that has never been seen before.
