... multiple barrier evaluation technology to prevent loss of pressure containment (LOPC) incidents. In addition, the method allows to extend the production life of wells with sustained annulus pressure (SAP) and continue operating those wells under specific conditions and periodic monitoring instead...

... Abstract Managing sustainable annulus pressure (SAP) is critical for maintaining well integrity since it poses significant health, safety and environmental (HSE) risks. For safe operation of the aging wells (40+ years old) beyond their design life, it is critical to accurately define maximum...

... Abstract Unplanned Sustained Annulus Pressure (SAP) in the A Annulus (sometimes referred to as the tubing/casing annulus or TCA), is the most common of all well integrity management challenges. Typically, this is as a result of a failure in a well integrity barrier envelope element / component...

... Abstract Monitoring and handling Sustainable Annulus Pressure (SAP) is a daily challenge in today's oil and gas industry. Well integrity failure can affect production and the environment and, consequently, lead to high economic losses from fixing the resulting damage. Once SAP is confirmed, its...

... implemented in 2007. The integrities of both wells were restored by eliminating the gas bubbles flow at surface, annuli pressures of well US-AA and eliminated the production annulus pressure of well US-AB. Restored tower Integrity, gas production and injection resulted in huge capital saving estimated...
