Q&A: Job well test with completion

Dear Test well team,

We had test the well but due to constraint budget with some host authority we test with completion string withouth PDG.
we tested the well with MRT and using SSD with thickness of reservoir based on log was 28 ft MD and 14 (4751- 4765) ftTVD.
our PDG at 4712 ft TVD
Our PVT gas SG 0.65, condy 49.8 and CGR 4.43
During built up, due to no downhole valve, we close at surface C/M.

I use the sapphir and use the model “changing the storage”

Here i attach some picture for your quick look,

I have question is it my methode is correct or not according to your experinces, and would you like to suggest what should i do for this.

Thank you
regards
