I could be wrong because I was also having a hard time hearing because of the wind in the video. I think what he was talking about is the acid was pushed far into the formation and it takes a while to get that back. Maybe it took a lot of fluid pushed downhole. Did he say the frac went deep in the formation or the acid? I do agree that it is nothing wrong just because the well has not came around yet. If it is there it will come see us "SOON" LOL
