Abstract
Methods and apparatus pertaining to determining shape and size of a borehole at a depth within a subterranean formation using ultrasonic measurements obtained by a downhole tool at four different azimuthal locations corresponding to four mutually orthogonal directions extending radially from a central axis of the downhole tool. The measurements are indicative of a distance between a wall of the borehole and the downhole tool at each azimuthal location. The borehole shape and size are determined by estimating an ellipse approximating the borehole shape and size using the ultrasonic measurements.
