... Abstract Long term wellbore integrity is crucial to produce a well for the entire life of the well. Cement sheath placed in annulus between casings and the formations experience high stresses under high temperature and high pressure which deteriorates mechanical properties of cement. This leads...

..., a new thermal-mechanical coupled model and analysis method for analyzing the mechanical response of casing-cement sheath-formation have been established. The model, which can be simplified to a plane strain problem, has considered the combined actions of temperature, pressure and non-uniform in-situ...

... good tool centralization in high wellbore deviations, and enables evaluation of multiples casing sizes in a single pass. The primary mechanical forces responsible for the failure of the cement sheath are shear forces differences between the wellbore and surrounding formation. The new technology...

... operation during the installation so that necessary remediation can be made to minimize the delays and losses of cement. At present there is no technology available to monitor cementing operations without using buried sensors within the cement sheath and also monitor the movement of the drilling mud...

... Abstract In drilling wells, zonal isolation is provided by cement sheaths. To maintain a good integrity to these cement barriers, it is recommended to optimize the placement of the fluids and thus the mud removal in the wellbore. It means that cement slurry properties like mixability...
