Beyond Traditional Methods: RFID Technology-Based Solutions for Upper Completions

Abstract

Traditional methods for isolating upper completion strings often involve complex, risk-prone, and costly intervention operations. This paper introduces a pioneering approach that leverages radio frequency identification (RFID) technology to eliminate the need for such interventions or conventional ball-drop systems. This paper focuses on the adoption of an intervention-less radio frequency identification (RFID) reservoir isolation valve (RIV) for upper completion installations.

Traditional methods for isolating, such as ball and seat, dart, and e-line conveyed intervention plugs, often introduce complexities, risks, and significant costs. These methods can lead to increased intervention time and technical challenges, particularly when circulating balls or darts onto seats. To address these limitations, an innovative RFID remotely activated reservoir isolation valve (RIV) was developed. This technology offers multiple built-in downhole contingencies, providing a more reliable and efficient solution for upper completion isolation. Following a thorough review of the operation requirements along with the associated historical challenges compared to conventional isolation methods, the intervention-less RFID RIV solution was developed, manufactured, tested, and subsequently deployed in a horizontal well. The technology is installed in the open position and is activated by specifically engineered RFID tags encased in a transportation carrier which allows it to be introduced to the flow stream and pumped to the toe of the well, even in highly deviated/horizontal reservoir sections. Once the RFID tag has reached the onboard electronics in the RIV, it passes a pre-programmed command to the RIV instructing it to close after a pre-determined time interval and isolate the upper completion. The programming logic also allows for built-in "timer" contingencies in the unlikely event that the RFID tags do not reach the tool as intended.

The RFID-activated RIV was successfully deployed in a challenging wellbore environment. The valve was activated on-demand by circulating the RFID tag to its designated location, ensuring precise and timely isolation of the upper completion. Subsequent operations, such as setting production packer, were carried out against the securely isolated upper completion string, enabled by the RFID RIV. This streamlined workflow eliminated the need for multiple intervention runs, significantly reducing operational risk and cost.

The RFID technology yielded several key benefits as enhanced wellbore integrity, improved operational efficiency, reduced risk, and increased flexibility. The RFID RIV provided a reliable and durable barrier, preventing fluid migration and ensuring wellbore integrity. The streamlined workflow and reduced intervention time led to significant cost savings and accelerated project timelines. Additionally, eliminating the need for complex and risky intervention operations minimized the potential for accidents and equipment damage. The RFID RIV's adaptability to various well configurations and operational scenarios further enhanced its flexibility and utility.

The successful deployment of the RFID-activated demonstrates the potential of innovative technologies to improve the efficiency, safety, and cost-effectiveness of well completion operations. By adopting this technology, the engineering teams can significantly enhance the efficiency, safety, and cost-effectiveness of upper completion operations.
