A method and apparatus are provided for obtaining measurements from a wellbore during tripping operations. A drilling sub is attached to the drillstring adjacent to or as near as possible to the drillbit before commencing normal drilling operations. Prior to commencing tripping operations, a logging tool is engaged within the drilling sub. The engagement of the logging tool within the drilling sub opens a window mechanism that enables the sensors of the logging tool to obtain data from the wellbore. As tripping operations are conducted, the logging tool obtains data along the length of the wellbore.
