Let me take a stab at it, while saying up front that all I know is what I've learned from reading these boards for three years.

Issues:
- volume -- we're talking about several thousand barrels per day of water. Again, it's nothing unusual -- this formation has produced much water over the years, while coughing up a billion barrels of oil. But 6000 or 8000 bbls/d is several hundred thousand gallons of water;
- composition -- it's not exactly potable water. What comes up from a well is typically saline for starters, and it's not unusual to have other contaminants, like sulphur, heavy metals and the like. So you have to be really careful to keep it away from ground water, acquifers, etc.
- temperature -- it's bloody hot water, which is a good thing for EOR operations, but unfortunately the composition is such that it's corrosive.

As I understand it, the ideal is to drill a water disposal well into a formation that can (a) take the volume, and (b) not communicate with other formations, acquifers, etc.

I think that's the direction you were looking for? Usual disclaimer -- others please correct my errors.
