The Sondex Diverter Basket Tool may be used in surface read out mode or in memory mode. It is run in the hole in the closed position, and opened to record measurements whilst the tool string is stationary.
Description
The tool utilises a patented fabric diverter element to divert well
bore flow up through a modified in-line spinner. By reducing flow
cross-sectional area this allows measurement of very low flowrates.
Also in multi-phase wells the tool minimises the effects of fluid
segregation. For more accurate holdup measurements a shroud may be
fitted to the exit of the in-line spinner housing to redirect flow past
the fluid identification tools above.
The 12 arm cage is opened and closed by a motor section at the lower
end of the tool with motor power supplied by a high current Lithium
battery or the line. The tool is opened and closed in response to
temporarily interrupting the line power from surface or from the MPL
memory recorder. For safety the tool will not open if motor battery
voltage is less than 14V, it will close if the spinner rotation exceeds
a pre-set level (where the PLT string is in danger of being lifted up
the well), or if battery voltage drops to below 14V.
