Apparatus and method for logging in boreholes with a non-circular section
Abstract:
An apparatus for logging in a borehole comprises a longitudinal body. A pad is coupled to and radially extendable from the longitudinal body toward a wall of the borehole. The radially extendable pad comprises a sensor. The radially extendable pad is rotatable about a longitudinal axis by a predetermined angle. A method for logging a borehole comprises extending a longitudinal body into the borehole; disposing a sensor in a radially extendable pad; coupling the radially extendable pad to the longitudinal body such that the radially extendable pad is rotatable about a longitudinal axis by a predetermined angle; and extending the radially extendable and rotatable pad toward a wall of the borehole.
