Well Integrity: A Holistic Approach to Annulus Pressure Management for Subsea Wells

Annulus Pressure Management refers to an engineered approach ensuring that casing annulus pressures do not challenge the well’s integrity during the life of the well. The aim is to maintain the casing pressure within the well’s mechanical design limits at all times by controlling the ‘A’ annulus pressure. 

The ‘A’ annulus is the annular space between the production tubing and the first string of casing (i.e. production casing) as shown in Figure 1.  In subsea wells, the ‘A’ annulus is the only annulus that can be monitored and controlled.
