Jie Xiao*, Jianghong Wang and Xin Sun

This paper discussed the mechanisms and processes in clay swelling. Various parameters used to predict the clay swelling processes were discussed. This study also shows how to select the suitable clay stabilizer for clay swelling control under different circumstances. Selection of clay stabilizers depends on the types of formation, the intrinsic the treatments. Different treatments require different types of clay stabilizers. Before applying any chemical treatment for clay swelling, knowing the mineralogy of clay minerals and locations of clay minerals is always being the first priority
