Free fluid control of oil well cements using factorial design

As worldwide demand of hydrocarbons is growing fast,the oil and gas companies are forced to explore reservoirs in more hostile environments. in these conditions,proper design of cement slurry is essential to guarantee the long production life of the well. free fluid content of the cement slurry is one of the main properties,which can leads to the formation of interacting channels through the set cement. the best way to achieve a good cement slurry design is to conduct a series of time consuming and expensive experiments. in this study,factorial design is applied to design a certain number of experiments and investigate the effects of possible additives on the performance of cement. using the experimental results,a simple model is developed to predict the free fluid content of the cement slurry. the given model shows accurate results and therefore can be used to minimize the number of experiments. © 2017,university of kuwait. all rights reserved.
