Abstract
A method includes deploying a logging tool in a borehole formed in a subsurface formation. The logging tool has a transmitter and a receiver. The method includes emitting, by the transmitter, a signal into subsurface formation. The method includes detecting, by the receiver, a response to the signal being propagated through the subsurface formation. The method includes creating, from the response, a borehole image that includes distorted features representing bedding dips in the subsurface formation. The method includes correcting the distorted features, wherein correcting the distorted features comprises mapping points of a non-circular shape in the borehole image to points on a circular shape.
