... Abstract This paper approaches the challenges of temporarily abandoned well monitoring with wet christmas tree (WCT), analyzes the regulatory requirements, the Brazilian scenario and proposes a new methodology system to checking the two Well Safety Barriers (WSB) integrity as required...

... the zonal isolation using an image map and to identify cement quality issues, such as channeling and the presence of microannuli. In addition, the casing integrity was evaluated in the same pass using the ultrasonic tool. The new ultrasonic tool makes it possible to achieve confirmation of well integrity...

... Abstract While developing an offshore well in Brazil, the integrity of a well under construction became compromised resulting from channel communication after cementing the production liner. Leaks in producing wells can cause formation damage, loss of production, and increase tubular corrosion...

... cement systems is low, hence there is the need for detailed analysis and action to prevent damage to cement sheath. This work demonstrates cement design procedures by evaluating cement sheath mechanical integrity in intercalated salts. A typical presalt Brazilian well with different lengths...

... The requirement for improvements to existing practices for the management of mooring system integrity has been bought into sharp focus in recent years, with the failure rate for FPS mooring systems being significantly higher than expected. This paper will provide an overview of the recently...

... and drifting off station. This can have consequences for both well control and riser integrity, resulting in huge costs for operators. Unless the operator inspects on a regular basis or monitors in real time it is impossible to know for certain whether all mooring lines are in place. A popular technique...

... control line integrity. ( Fig. 2 ) Thus, it becomes possible to change any part of the upper completion such a non-functioning safety valves, electrical submersible pump (ESP), or other component without recovering the lower completion. In addition to the time saved on well interventions...

... Abstract A well planned and executed Structural Integrity Management (SIM) program is the cornerstone of managing structural risks and it can greatly reduce unplanned, undesired and extremely costly in-situ structural repairs on floating offshore facilities. However, the level of effort...

... (e.g., platforms). Advances in computational power permit specialized software to evaluate safety concerns. Major safety concerns associated with offshore installations can be examined with particular attention paid to structural integrity, deformation and any impact on personnel safety (evacuation...
