ORIGINAL: Archer I was EHS (Environmental Health and Safety) at ARCO before BP bought them, LOL but I worked at the lab that did enhanced recovery research for the prudogh bay and some other areas. Refining not my strong suit either but I did learn a thing or two about crude oil and the various grades. and the product percentages you get from them. Another thing about sour/ heavey/ extra heavey crude is the percentage of gasoline you get per barrel of crude. lighter oils (light sweet) you get 30% or so gasoline and such products when you move to sour you drop down closer to 10 or 15%, and when you get down to extra heavy you get 5% gasoline. A major reason we still get so much from the middle east, (very light sweet). I was all ERRD (Enhanced Recovery Research Department) when I was w/ Shell in Bellaire. Chemical stuff. Some polymer work, mostly alkaline (alk foams too) and surfactant experiments, and a pilot project in Whie Castle. LA, south of Red Stick. Had 3 labs devoted to it. Alkaline was usually Silicates, OH- converts petroleum acids to soaps, soaps form a high-viscosity emulsion which drives out the oil in front of it. Had up to around 80% recovery under lab conditions (low pressure, formation temp, unconsolidated medium). Had to work up a wet lab silicate analytical technique derived from some Russian inorganic chem journal (pre-interwebs, library was most engineering/geology/metallurgy/organic chem stuff). Interesting stuff. In-situ cat-cracking will probably be used extensively in heavy-crude formations soon (if it isn't already; I'd have to do the research). Guys... could you get just a tiny little bit more technical please ? Nah, they know it makes us nerdettes hawt hawt hawt! thornhappy
