- [Voiceover] Well, good afternoon everyone, and appreciate you attending this webinar. I'm going to be moving fairly quickly through the slide, and I want to emphasis that, you know, this is gonna be kinda all over the map, it's gonna be an interesting presentation, but it will be moving. But before we completely start, I always like to put up my disclaimer statement, since that seems to be the vogue of the day, and I've written it in the smallest font I could find down at the bottom of the page for people who prefer it to be in fine print. Now, more seriously. Where we're going today is with concepts of scale that you may have remembered the days back when your English teachers were talking about recurring thematic elements. Well it occurred to me that concepts of scale just keeps on happening, recurring in so many different ways in all the things that we do with our Wolfcamp shale oil efforts. Our discussion today is going to be broken into two parts, geosciences and engineering for more technical group set of discussions, and then the second major group will be things that impact everything that we try to do technically as geoscientists, and that's the land and the capital and the partnership issues, which can actually have more impact than the actual technical issues sometimes. But, again, I want to emphasize that this is a fairly random, eclectic group of topics, we're not delving deeply into any one subject, we're trying to, I'm trying to present some of the issues as it were posed to me in question form from David Ensminger back last year, when he asked me to put one of these talks together, and basically, it was, you know, what were the problems, what were the issues, what things would you have liked to have known about before you got started in the play? If we had perfect knowledge, and so, that's what I'm trying to do, is answer some of the issues inspired by his question. So let's move right on into some of the geoscientific topics.
