... satisfactory standoff of the liner in relation to the wellbore or poor mud conditioning before the cement operation. During cement slurry displacement, a preferred circulation path for the cement slurry may cause poor or even nonexistent isolation. An even greater challenge is remediating this type of failure...

... of these waters, becoming the massive salt formations, one of the major challenges faced, not only for drilling methods and techniques, but for zonal isolation in general terms, related to cementing operations. Cementing jobs executed in salt environments require cement slurries with specific concentrations...

... cement-slurry placement. Additionally, lost circulation materials (LCMs) should be incorporated into the cement slurry to help control loss zones. This paper discusses the field implementation procedures and the cement-slurry design tailored for deepwater wells in offshore Brazil, which helped minimize...

...% on the total drilling time. The saline and production zones are cased and cemented in the same phase, requiring a cement slurry design that minimizes salt dissolution and, at the same time, has specific properties for production zone isolation. The quality of this cement job is key for the success...
