Update On EOG's Waterflooding Experience In The Bakken

From a recent EOG presentation:
Specifically on the waterflood, we have a waterflood pilot going on now in the Bakken and there has been a bit of -- quite a bit of studies from the universities and we have done our own in-house study. And when you put water on the Bakken, it absorbs the water and it expels oil, in the lab. So that's good in the lab but you got to figure out how to do it in the field. And we did our first pilot on our -- when we were on our 640 acres between spacing, one well per section and basically, we just did not get any answers there.
It basically told us that 640 acre spacing is much too wide to try that kind of process.
So as we go into the core well per section, kind of senior that we're in now and we're doing a better job with the frac connecting up more reservoir, we'll go back in and retry these waterflood efforts there. But I think we're optimistic that in the better plays, again that's the advantage of having a better rock, the better the rock is the more conducive it is the secondary recovery. So in the Eagle Ford, we're doing dry gas injection pilots there and in the Bakken we're doing a waterflood pilot. So in at least those two plays we're optimistic that we'll find some mechanism to enhance the recovery over time. We haven't proven it yet but that is a process we're very much engaged in.
