The first operational decision, prior to the application of pulse testing, is the determination of the pulse durations, i.e. the fundamental period. This parameter depends critically on the expected reservoir properties and on the pulse test configuration. Expected values for the parameters can be used with the theoretical relationships to determine for what values reasonable signals can be expected. This is also related to the choice whether monitoring is employed in the pulser well only or also in an observer well.
The number of pulses must be sufficient to obtain the frequency information. Usually, 7 to 10 pulses suffice.
To be able to obtain a maximum amount of useable frequencies, high-quality data are required. The least critical component of the data is the : it should be in the order of 5 to 10%. More important are timing parameters. Firstly, the sampling rate should be high enough – for instance, for one-hour pulse durations, a sampling rate of 5 seconds. or higher is preferred. Secondly, the moment of switching between rates should be controlled to within 2 or 3 times this sampling rate. Otherwise, higher frequencies will not appear clear enough in the frequency spectrum. Finally, the clocks for sampling the rates and the pressures should be synchronized to the same precision. A mismatch has a direct impact on the delay, with linearly increasing effect for increasing frequencies.
