1 INTRODUCTION Pulse Testing is a new method of reservoir evaluation which has been developed for describing formation properties between wells. Pulse-testing utilizes a sensitive differential pressure gauge at a responding well to measure and record the response generated by a series of flow rate changes (pulses) at an adjacent or pulsing well.

2 Use of Pulse Testing The time required is only a fraction of that for an interference test because a special, high-sensitivity differential pressure gauge can detect a much smaller pressure change. Variations in properties between individual wells can be delineated because of the relatively small volume of the reservoir disturbed during these short times. Finally, wells other than the pulsing and responding wells do not have to be shut in or carefully regulated.

4 Pulse Testing Procedure
A well pair consisting of pulsing well and responding well is considered. Then a series of pulses or flow disturbances is generated in pulsing well. This series of pressure transients propagates through reservoir and reaches at responding well . The pressure response is recorded at responding well with the help of very high sensitive pressure gauges. Then from the known data of flow rate , pulse time and in between pulse time and pressure response data, time lag and response amplitude are calculated.
