Methods of Orientation Direct Method
Methods of Orientation Direct Method : Magnets embedded in the non-magnetic drill collar are used to indicate the position of the tool face with respect to magnetic north. A picture of a needle compass pointing to the magnets is superimposed on the picture of a compass pointing to magnetic north. By knowing the position of the magnets in the tool, the tool can be positioned with respect to north. Indirect Method: A method of orienting deflecting tools in which two survey runs are needed, one showing the direction of the hole and the other showing the position of the tool
