00055:16 Q. Lost returns is a situation
17 where you're injecting mud down, you expect
18 to get it back up with the cuttings, but
19 you're not getting it back, you're losing
20 it to the formation?
21 A. Sure.
22 Q. Lost returns, to put it bluntly,
23 is a bad thing, right?
24 A. Yes.
25 Q. Okay. And it's a bad thing
00056:01 because you have fractured the formation
02 and you cannot drill when you lose returns?
03 A. Yes.
Page 56:22 to 57:06
00056:22 Q. All right. With respect to this
23 issue of drilling into weak goo or possum
24 shit and leaves as opposed to hard rock,
25 why is that relevant or important to keep
00057:01 an eye on when you're drilling?
02 A. The less consolidated formations
03 will be more susceptible to fracture.
04 Q. Why?
05 A. They have a lower tensile
06 strength.
Page 58:10 to 58:15
00058:10 Q. Sure. And I don't mean to
11 oversimplify or demean the, you know,
12 importance of what you do. But the idea
13 that your hydrostatic mud weight needs to
14 be in line with your pore pressure, I mean,
15 that's just basic physics, isn't it?
Page 58:18 to 59:25
00058:18 A. I don't know how physics applies
19 to it necessarily.
20 Q. If you put something into the
21 well that is heavier --
22 A. Yes.
23 Q. -- than the pore pressure, it's
24 not going to want to rise up relative to
25 the gas, is it? It's going to want to
00059:01 sink?
02 A. There's, perhaps, other factors
03 in play. There's -- there's a certain
04 degree of uncertainty. I don't believe
05 it's that clear-cut.
06 Q. But in terms of what is
07 clear-cut, if your hydrostatic mud weight
