This test looks not usual and un-interpretable
The injection periods was not stabilized (not a constant injection rate for each period).
The well closed while fall off test which caused a vacuum during falling the water into the formation (common problem in fall off test).
What you can get from this test is:

- Injectivity test
- Reservoir pressure
- Skin factor

Thank you for your reply.
can you tell how you know this situation "The well closed while fall off test which caused a vacuum during falling the water into the formation (common problem in fall off test)." ???

and another question how can i get skin factor if i can't select permeability slop???

thanks in advance.

dear Fanarco,
as you said about the P@dt=0 this problem indicating that the last Pwf is not correctly assigned. i.e. in many cases the Shut in from well head doesn't prevent well to flow at sand face.
i try to change P@dt=0 manually but i didn't get the match between Dp line and derivative line in well-bore storage period i can get match only on the starting point!!
but when i move the line of last draw-down to right i get a good match between the two lines! but with the different skin result!

which way is give us a right results??
and where exactly select P@dt=0 in the pressure history plot?
