<p>In the representative embodiments of the new and improved methods disclosed herein, a cable-suspended spinner-type flowmeter is successively raised and lowered at different selected speeds in a well bore containing one or more flowing fluids whose velocity or flow rate are to be determined. In one manner of practicing the invention, output measurements obtained from each of these runs are plotted versus the respective travel speeds at which the tool was moved to uniquely derive one or more correction factors from which the velocity and flow rate of each increment of the well bore fluids can be accurately determined.</p> |
