1. C15/C16 is the "worst" level. As they go up, the flows will increase.
2. They didnt perforate twice - just once and the acid was injected into the same perforations. Lets see the next NR
3. They can come back to this level later and try to properly clear it after the other 3 are tested. Why you ask? Because if they get 15-50 mmcf from the other 3 levels combined, they may decide not to mess with C15/C16 anymore. The gun may provide some answers.
4. C15/C16 still has the same amount of gas they did before - nothing changes for any other well drilled or the field. C15/C16 is a bonus.
