A method of measuring the azimuthal strike orientation of a planar rock fabric feature in a subterranean formation, which method comprises the steps of: (a) drilling an oriented core through the formation, the oriented core containing principal and secondary scribe lines; (b) recovering the oriented core; (c) taking a computed tomographic scan image of the oriented core; (d) identifying the planar rock fabric feature from the computed tomographic scan image; (e) creating a planar rock fabric trace by translating the orientation of the planar rock fabric feature through the geometric center of the scan image of the oriented core; (f) measuring the angle between the planar rock fabric feature trace and the principal scribe; and (g) converting the measured angle to an azimuthal strike orientation. |
