Abstract This paper proposes a new method for designing 3D trajectory in sidetracking horizontal wells based on optimization theories, in which some factors such as kickoff point, performances of bent housing motors, and tool-face angles etc. are considered quantitatively. The validation of this method is shown by more than 10 case histories. Comparison with conventional methods, the new method can greatly simplify the design process, generate more smooth curves with less length and can hit the predetermined point or target with higher accuracy.
