Tertiary gelation of oilwell cement
The aim of this research was the investigation of the origin of the oilwell cement slurry gelation problem which can appear during well-cementing operations. In this study, the relations between the development of consistency of cement slurry, the hydration process and surface growth in the paste were studied for several commercial oilwell cements. The effect of gypsum content on the consistency of cement slurry was evaluated. In order to relate the hydration process and the consistency development, the hydration of cements was followed by thermogravimetric analysis (TGA), X-ray diffraction and by proton NMR spectroscopy. A comparison between the results obtained and some published data is presented.
