Abstract Floating Production Systems (FPS) remain on station many years without dry
docking. The mooring lines, which ensure station keeping, are designed to last the entire …

Predicting the pressure behavior of annular fluids during production and injection operations
in oil wells became a major research topic in the exploration of deep-water reservoirs …

This article aims to present the evolution of well design and well integrity monitoring
throughout their life cycle and life extension analysis. The motivation comes from the need to …

Temperature increases and creep in saline rocks can cause annular pressure buildup
(APB), presenting a significant challenge in oil well operations, particularly in deep and ultra …

A physical evidence of an injector well failure caused by transient thermal behavior in
cooling operations has lead to technical actions in order to provide a safe operational …

Subsea wellhead design has always rendered the B annulus on subsea wells inaccessible
for monitoring. One of the leading causes of sustained casing pressure especially inside the …

This paper proposes to explore the application of new operational limits for wells under a life
extension in mature fields and wells subjected to changes in production parameters caused …

A cascade casing collapse occurred in a well in the Santos Basin was caused by the thermal
transient effect, as discussed on Moreira Jr. et al, 2019, leading to operational restrictions …

During production start-ups and shutdowns, the ASA (Annulus Seal Assembly) is subjected
to compression and tension cycling loads, featuring the normal condition loads, and for this …
