Abstract
A method for detecting an object in a borehole includes acquiring at least two ultrasonic logs of a borehole section. Each of the ultrasonic logs includes ultrasonic measurements taken at a plurality of tool azimuths of a plurality of depths including a target depth. The method also includes inferring a VDL image relative to the target depth for each of the ultrasonic logs. Further, the method includes aligning the VDL images. Further still, the method includes merging the aligned VDL images into a high-resolution VDL image. Even further, the method includes detecting an object present in the borehole based on the high-resolution VDL image.
