1 DR. AYERS: Obviously, the volume of cuttings would be large. The 



2 signal that you see from it, you know, you do see more barium and you 



3 can follow a gradient further with the other associated trace metals 



4 beyond barium. Again, that signal falls back off to background still 



5 fairly close in. 



6 The barium signal, though, does stay elevated fairly far out to a 



7 couple thousand meters, but again, I bring it up to make a point that, 



8 you know, you don't see 26 times as much of everything out there just 



9 because you had 26 wells. 



10 Anyway, that's a general scenario of a development drilling type 



11 of operation. The discharge volumes, over a period of time and on a 



12 daily basis, are the same as an exploration. The difference is you've 



13 got one well after another discharging in the same location. 



14 We might drill something like five or six wells a year at that one 



15 spot and we'd be doing pretty good. 



16 DR. RAY: Depending on the depth of the wells. 



17 DR. VALENTINE: What happens after the platform is totally--after 



18 all the wells are drilled and it is in full production? Are there any 



19 different activities that cause pollution, like tanker--spillages from 



20 pipelines or tankers? 



21 DR. RAY: Once the drilling phase is done, depending on how that 



22 platform is produced, you really have two options. One is to pipe to 



23 shore from platform; the other one is that you lighter off onto a tanker 



24 for transportation to shore from there. 



25 A third scenario is the production ship, like Exxon did out in 



26 California but that's almost a one-up type of operation to do that, so 



27 most likely, you have a pipeline operation. 



28 You have the possibility of pipeline spills if you had a pipeline 



29 rupture. The key thing from the platform, other than domestic discharge 



30 and deck drainage, which are two key ones in produced water. If the 



31 platform is a production platform that does the production work right 



32 there, then you have the discharge of produced water, which is usually 



33 done right at the surface or shunted just below the surface.
