| Abstract:With referemce to the first case of cutting a window in the dual case set in a directinal well for side traking process and its effect in directional wells. Methods of incteasing side tracking efficiency and reducing cost are presented It is concluded that whether side tracking in derectional wels succed or not mainly depends on the orientatio of the deflection wedge. |
