Ann: Operations Update, page-195

Actuallt Warnie I was thinking about this.

Whilst not an expert, it occurs to me that;
1. If you pump in 100% under pressure and get back 100% very quickly under pressure then the rock has not fractured and that is bad
2. If you pump in 100% under pressure and you get back 0% then the fluid has gone away meaning that the area is to porous to hold liquid and that is bad
3. If the top and bottom layers connected under pressure, then it isn't cl;ay down there is it?
4. So you don't want it all back under high pressure and you don't want it all to disappear and have no pressure, so ALL = BAD, NONE = BAD, SOME = GOOD.
5. You want some flow back under its own pressure, the $$ question is how much is good and how much is bad.....
