  • 3D Design of Optimum Complementary Boreholes by

    In the third step, a set of 3D candidate complementary boreholes is designed. In the fourth step, scores along the candidate borehole, relevant to various criteria, are estimated. In the fifth step, the candidate boreholes are ranked using a multi-criteria decision-making algorithm and an optimum borehole is selected for further drilling.
