Hello ratih,

Welcome to your forum FANARCO..

The Difference is that both cases the well is SI but in Pressure build up the well is shut in after a flowing period and you should put the flow rate or the production history in positive value.

In Fall-off testing the well is shut in after the injection period and you should put the production history in negative value which is (in common) water.

If this answer not satisfy you please tell me to provide you with more details
