Patent ·
OSTI ID:5400931
A method is described for displacing a logging tool through a nongravity descent portion of a well, comprising the steps of providing a logging tool at the lower end of a drill pipe as an exposed extension to the drill pipe, displacing the tool thus exposed through the non-gravity descent 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.
