Fines Migration: Problems and Treatments

Jie Xiao, Jianghong Wang and Xin Sun

Fines migration can cause severe damage to formation permeability and can plug the formation under certain circumstances. To effectively address this address, the mechanisms of fines migration and factors that causing fines migration were analyzed in this study. Different treatment techniques were discussed in this paper and the newly application of UTTA has been very successful in most formation types. The films it forms can enhance the ability of formation to withstand high shear stress and high flow rate. Lab core flow tests demonstrated this positive effects and it can greatly minimize the side effect of acidizing treatments, as a post-treatment method.
