Abstract
A deviated borehole penetrating a subsurface formation and intersected by a formation fracture is surveyed with a borehole televiewer acoustic logging system. Relative fracture dip angle and dip direction calculated from such survey with respect to the borehole axis is transformed into a true fracture dip angle and dip direction with respect to the vertical of the earth's coordinate system.
