El Paso: Geology

OK, this is my last post from El Paso Corp's analyst event, but I couldn't pass it up. I'm fascinated by the geology of the Haynesville Shale, how it used to be a depository for organic material from rivers 150 million years ago. On this site, I like to show the different takes on the geology of the play. I especially like the first El Paso slide below, which marries a map view with a cross section. It is one of the few images that successfully illustrates what is going on beneath the surface to non-geologists like me.

When I was in high school I worked summers at a geology and petroleum engineering consulting firm. One of my more tedious tasks was to catalog the thousands and thousands of blueline Schlumberger log reports. Those logs were folded accordion style and could be longer than 20 feet. I used to write the S/T/R numbers on the special small file folders and then file them in the appropriate drawer. I have a vivid memory of the geologists sitting in their offices poring over those reports with a red pencil in one hand circling particular jagged lines that caught their attention as they flipped the folds. I was always fascinated that they could see important data in all those lines. It just looked like static to me. It still does. I'm just glad images like those below mean something to those geologists.
