Abstract The weight loss of cement slurry is the main cause of early annular air channeling and accurate experimental
evaluation of the law of loss change is the key to achieve compression stability and prevent this undesired phenomenon. Typically, tests on the pressure loss of cement slurry are carried out for temperature smaller than
120°C, and this condition cannot simulate effectively the situation occurring in high temperature wells. For this
reason, in this study a series of experimental tests have been conducted considering a larger range of temperatures, different retarders and fluid loss additives. The results show that with an increase… More >
