| Abstract: | In this paper, a new method is proposed to calculate the parameters related to directional coring and deflection in drilling practice. This method is based on the principles of stereographical projection. The formulas derived from spherical triangle explain and improve the graphical treatment of directional deflection and coring. Two examples are given in the paper to show how to use the new method to calculate parameters pertinent to directional coring and deflection. |
