..., correlation of the tables in API Recommended Practice 10B are usually chosen to predict bottomhole circulating temperature (BHCT), but both are not suitable in every block with a different geological condition. To design thickening time of the cement slurry, it is necessary to give a credible temperature...

...K. Harestad; I. Karimfazli; A. Ghazal; M. Harestad; A. Saasen Summary It is shown how the flow from pumping cement through an open-ended pipe very quickly changes direction and the cement flows upward. This rapid change in flow direction indicates that a diverter tool, which leads the cement slurry...

.... Formation fluid inflow takes place when the hole pressure is lower than the formation pore pressure. This results in the contamination of the cement slurry with the formation fluid and/or the creation of fluid-induced channels in the cement. Wellbore breakout ( Guenot 1989 ) is attributed to rock failure...

The HSC of the cement-formation interface was likely to be compromised if the cement slurry was contaminated with a spacer and oil-based mud (OBM). When the cement...

... in the design of gas-tight slurries. Although cement slurries under controlled conditions in the laboratory can be gas-tight, the in-situ performance of cement slurries is highly variable and difficult to predict. Therefore, a new approach has been designed to evaluate gas-migration potential under a range...
