Abstract
Method for displacing a logging tool through a non-gravity descent portion of a well such as a highly deviated portion, comprising the steps of providing a logging tool at the lower end of a drill pipe as an exposed extension to said drill pipe, displacing the tool thus exposed through said portion of the well by connecting additional sections of drill pipe and lowering the drill pipe, and, during this displacing step, continuously generating and sending uphole a signal indicative of the compressive load undergone by the tool.
