Paper presented at the SPE/IADC Middle East Drilling Technology Conference & Exhibition, October 7–9, 2013
Paper Number: SPE-166799-MS
... Abstract Drillpipe (DP) work strings are used for continuous operations during the drilling phase and also for various cementing operations, such as running casing, liners, casing with inner string, squeeze jobs, and balanced-plug cementing. There are reported cases of residual cement adhering...

...Kristian Harestad; T. P. Herigstad; Arne Torsvoll; N. E. Nødland; Arild Saasen Summary Placing properly balanced cement plugs in wells has been a serious problem to the drilling industry for decades. The cement plug is rarely found at the desired depth. Because of the fact that the cement slurry...
