It looks wet. That's because the volcanics changed the log response. On a lot of the logs that we see, and if you look at what Great Bear has done with the pipeline state's well which is the black dot just above the peak of the bow, they're saying that that's a discovery because they've gone back and done some forensic analysis on the logs and calculated the impact that these other materials in the reservoir have on the logs and say, "Look, we can now see based on what these other discoveries that have been made that this looks the same and therefore, simplistically, this has oil in it." Whereas before, people would have thought it was wet.
wash out but not in Icewine :-)
"We've started doing similar work, and Steve alluded to that. We need to do more of that work. One of the challenges is that some of the log quality is quite poor in some of these wells. They've had what's called wellbore washout where the shape of the hole expands and gets quite rugose. When that happens here, your logs become ratty and not very reliable. Reconstructing them sometimes is just not possible. When we go back and look at Malbec and Smilodon that Steve talked about, in the interval where we see this reservoir, hopefully it's a reservoir coming through those wells, we can't see a lot on the logs. When you look at the mud log, they've got oil shows throughout the ascensions.
Unfortunately, and this is a funny way to say it, there's a lot of oil shows on the slope. That's obviously a good thing. However, it doesn't make it differential for us to say that is definitely something. We know the oil is there. You can't tell from the logs whether there's actually bypassed prior reservoir there. I assume that we currently know it, but we're going to do more work to try to improve upon that. If we can, that's the maturation that could lead us to say, "Bang, we're going to go and drill Bravo and Charlie.""
