Abstract
Reverse circulation drilling is one of the most effective drilling method on drilling of high capacity water supply wells in soft sedimentary aquifer. Technological process of reverse system are: - Counter flush drilling system - Suction drilling system. - Suction jet drilling system - Air-lift drilling system Based on drilling theory and reality of applying of RC drilling method, all the RC drilling systems will be analyzed for choosing the suitable system for Nambo area.
