Abstract Globally, hundreds of wells each year face challenges related to unplanned sustained annulus pressure (SAP). Operators need to invest significant costs, time and face HSE risks to either fix the SAP issue or put in place risk reduction measures to operate these wells under dispensation, in order to avoid workovers, production deferment or inactive strings. This paper presents an innovative solution aimed at optimizing well integrity and production efficiency for operators facing problematic sustained annulus pressure (SAP). By combining efforts to minimize inactive well strings and enhance real-time surveillance, the solution focuses on increasing well availability while reducing intervention costs. The technology restores double barrier integrity at the surface, provides reliable and real-time annulus pressure and temperature data, and autonomously manages the SAP pressure within predetermined thresholds. This approach enables a comprehensive understanding of SAP, facilitating the continued production of wells that would otherwise require workover, thus contributing to production quotas and improving HSE standards.
