Spinner/Flowmeter measures vertical fluid velocity in a pumping or non-pumping well. Asensor counts the revolutions of a mechanical impeller as the tool descends or ascends in the well. Aproduction profile of thepumping well can be determined over the entire perforated interval. With a continuous record, Q values from any interval can be measured without interpolation. Hydraulic conductivity can be derived, aiding in well design and ascertaining production problems. Combined with our depth specific fluid sampling system, the spinner can be used to determine concentration of specific constitutes when chemical analysis is available. In non-pumping wells, the spinner can locate confining zones and calculate fluid velocity between zones.
Spinner diameters are either 1” or 1 11/16”. The length can range from 24” to 5 ft, depending on configuration. The 1” spinner is primarily used in small tubing or when the need arises to pass tight clearances, such as pump bowls.
