question for the smart cookies, page-2

Brabus,

exactly. They returned 45 barrels of testing fluid, which begs some questions:
- is the fluid lighter than oil?
- does acid-fracturing expand with time (liquid converts to some gas type) thus causing pressure to ensue without movement of oil?
- does acid-fracturing restrict some oil flow until it is cleaned from the face?

I really don't mind if someone says it's a dud, but they need to give a DETAILED explanation WHY! Otherwise, they are just offering dribble just like me - Personally, I'd like to learn, so detailed explanations are most welcome if you have come from valid knowledge and life experience within the industry.
