... Abstract The cement between the casings and formation is a critical barrier element for ensuring zonal isolation. Shrinkage during curing and mechanical or thermal loads applied during production can compromise the cement and result in fluid migration paths such as micro-annuli. The fluid...

..., and also the high number of potential flow zones to be isolated, the client has decided to run a 13 5/8" stage collar in order to isolate all sandstone formations and cement the combined 14" × 13 5/8" Intermediate Casing. The idea of using the stage collar was to isolate the water holder formation...

... Abstract Well integrity and zonal isolation are crucial in deepwater wells requiring accurate cement bond log analysis. These wells require high mud weights and/or thick-wall casing strings that can prevent the use of some tools and, in the best case, result in a significantly reduced response...

... lost circulation issues were expected. Cementing operations in such conditions can be challenging and require special attention to cementing the drillstring and completely achieving zonal isolation objectives. During preplanning, foamed cement was considered based on its ability to mitigate formation...
