November 25, 2025
Monitoring annulus pressure is crucial for maintaining well integrity and preventing potential leaks or blowouts. However, offshore platforms’ remote and often inaccessible nature poses significant challenges for effective monitoring.
NEON LoRaWAN Pressure Sensors, combined with IMI TWTG SolidRed Software Suite, offer a comprehensive solution by enabling continuous, remote monitoring of annulus pressure without the need for direct power or network connections.
The challenge
Offshore annulus pressure measurement plays a vital role in regulating pressure and ensuring the integrity of oil and gas wells. However, monitoring these pressures presents challenges due to their remote location and the logistical difficulties of accessing offshore platforms. Traditional monitoring methods are often costly, labour-intensive, and prone to delays, increasing the risk of safety hazards and environmental damage.
The solution
NEON LoRaWAN Pressure Sensors, integrated with SolidRed Software Suite, address the challenges of offshore annulus pressure monitoring. NEON sensors operate autonomously, requiring neither direct power nor network connections, making them ideal for remote offshore environments. SolidRed Software Suite provides a centralised data analysis and visualisation platform, allowing operators to monitor annulus pressure data in real time and receive alerts for potential issues.

Key benefits
Remote monitoring: NEON sensors allow continuous monitoring of annulus pressure on offshore platforms, eliminating the need for costly and labour-intensive manual monitoring trips.
Cost efficiency: By reducing reliance on manual monitoring methods, NEON sensors help oil and gas operators save on operational costs and minimise downtime.
Early detection: Continuous monitoring enables early detection of potential issues with annulus pressure, allowing operators to take proactive measures to prevent leaks or blowouts and ensure the safety of offshore operations.
NEON Pressure Sensor with Gauge, ATEX and IECEx Zone 0 certified, wireless and battery powered, designed for digital and analogue workflows in offshore annulus valve monitoring.
Successful deployments
Several oil and gas operators have successfully deployed LoRaWAN NEON Pressure Sensors integrated with SolidRed Software Suite for offshore annulus pressure monitoring. One such operator, operating in the North Sea, deployed NEON sensors across multiple offshore platforms. Combined with SolidRed Software Suite, these sensors provided continuous monitoring of annulus pressure and real time data analysis, enabling the operator to detect and address potential issues promptly. As a result, the operator was able to improve safety, reduce downtime, and optimise operational efficiency across its offshore assets.
Conclusions
Implementing NEON Pressure Sensors for offshore annulus pressure monitoring represents a significant advancement in well integrity management for the oil and gas industry. By enabling continuous monitoring of pressure located on remote offshore platforms and providing real time data analysis capabilities, this integrated solution offers a cost-effective and efficient way to mitigate risks and ensure the safety and integrity of offshore operations.
