The outlook of ultradeep scientific drilling operations are smmarized.This review was conducted to infer the reason why the synthetic hectorite has been applied to the drilling muds. the results obtained are summarized as follows. 1.The viscosity of synthetic smectite-NaCL suspensions showed the maximum value called viscosy hump at the NaCL concentration of 20 meq/l approximately. 2.In a hydrothermal condition, Na-montmorillonite was easy to change , however, Ca-montmorillonite showed no significant changes. 3.Synthetic saponites showed a crystal growth with increasing hydrothermal duration at 300℃, and they also kept to have physicochemical and rheological properties. The observed differences of synthetic and natural smectites were discussed in relation to rheological behaviors and hydrothermal stabilities.
