86. Why would pressure be down? Because...
The oil well has been producing oil for two months at very high rates. The flowing oil requires energy to move it from "out there" to the well itself. This induces a pressure drop. So one thing we know for sure is the pressure is down. I'd guess at least 500 psi. If you are trying to pump water to flood it out, the amount of water to be pumped depends on the thickness of the oil reservoir, and how close the injection well is to the blow out well. Say you set the injector as close as 20 feet, then the water should show up at the producer in a matter of days. If the injector is pumping in 100,000 B/D (and this would take some mighty pumps as well as a very large pipe diameter), then the water being pumped in should overwhelm the oil - or at least it should cut the amount of oil so much, then the top kill can be tried successfully, because a water column sure weighs a lot more than an oil & water column.
