- [Teacher] In conclusion, what I wanted to point out to you is that so often all of us that are in petrophysics know that by the time we get to a production stage in a reservoir, our managers like to have just a cased-hole gamma ray running wells. It may be nothing else, just for correlation purposes, and this particular paper, this presentation, shows you how important it is to get other data because although we didn't see a lot of breakthrough, or matter of fact, we didn't see any breakthrough unless there's a fractured system, we were able to get Archie Ms and Ns determined for each of the sands. We had a whole, as they say, 25 identified sands up and down the reservoir. Get a better oil and place determination just to hit all these Ms and Ns and you get a better saturation model. And as we can see down here, because we can determine from it what saturation models were appropriate. And we use the dielectric logs to determine where we had depletion. We also were able to use it for relative permeability data because you didn't see it. And you'll read in the paper, it was just published in October in Petrophysics, we can get endpoints for the relative permeability curve, residual oil saturation, and irreducible water and we can get the N value and show where we had water wet sand. So I guess the bottom line was we were able to understand this reservoir a lot better, determine where we need to perforate. Obviously where we had depleted zones, we didn't want to perforate there. Where we had invaded, where we had flood waters coming in, we didn't want to perforate there for the completions of going from 20 acres to ten acres. So with that point, thank you very much for your attention.
