Question / Answer

At what flow rate should I survey?

The flow rate for surveying is variable based on well conditions and will change as measured depth increases.  When the pumps are started, the flow of fluid acts on the pulse knob at the top of the tool and forces it down past a series of restrictions, creating the pulses that are read at the surface.  Pumping too fast will force the plunger down to quickly and you may not be able to decode all the pulses at the surface.  Pumping too slow will delay the pulse knob passing the restrictions, cause weak pulses, and you may not receive all of your pulses in a timely manner.  Do not adjust the pump rate during the survey as this may create a false signal.

Ask your authorized Teledrift representative for assistance in determining an optimum flow rate to survey.
