I have been wondering, and haven't found much literature on the subject of applying GIS to the E&P chain. I can see it would be useful, but can't exactly see where and how. Also note, that I am coming from a geology background, now working with reservoir geophysics, and that one of my previous jobs was with GIS in the Brazilian Geological Survey. I can see GIS helping with facilities management, decicion support, but all that is not related to G&G (geology and geophysics), but more to the engineering aspect of the E&P chain. If any of you has any experience, or relevant pointers, I would like you to share some. This is important for me because I would like to get back into GIS, and found that I need to convince my boss(es) that I need to pursue a Master's in this field (Which is what I want). -- Paulo Marcondes = PU1/PU2PIX -22.915 -42.224 = GG86jc _______________________________________________ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
