Televiewer logs from drill hole GT-2 at the Fenton Hill, New Mexico, Hot Dry Rock Site, have been rectified by conversion of structural traces on the scanner imagery to geographic location and orientation. The rectification method was direct inversion that consisted of mapping from the image to the wellbore, inverting the trace on the wellbore for principal points, and rotating from wellbore to geographic coordinates. From the test imagery of GT-2, 733 structures (fractures and foliations) were measured, compared with 42 structures from recovered core. The 733 new measurements listed in this report are a unique and unrepeatable collection of structural information from the Precambrian basement of northern New Mexico. This direct inversion method is accurate where the magnetic field vector is constant and the tool is centered and aligned in a circular wellbore. In other cases this method yields only approximate results.
