Something to consider: If we see $10 oil, there will be a world-wide crisis. We could see revolution in Saudi, depression in Russia, Indonesia in civil war, Ven. falls off into the ocean, etc. In other words, you can probably kiss the whole mkt goodbye except for the airlines. I don't think there's a chance of that happening. The powers that be will not allow crude to reach those dangerous levels. Too much uncertainty would be the result. I'm off to the golf course. Watch the store! -Lucretius

Bob, <<<Would anyone give me a run down of what the technique of "frakking" is in the oil& gas industry? Thanks, Bob>>> Frac'ing or fracturing is a process of pumping a mix of usually sand and a special liquid, which is usually a gelled substance, under high pressure down a well through the perforations to fracture, or open up the formation. When the formation has fractured the sand grains are pushed into the newly formed and opened fractures and continue to hold this fracture open. This allows oil and other fluids to flow easier to the wellbore, where by increasing production. There are other types of fracturing but the processes are similar. Paul

Bob, Did anyone explain "fracc-ing" to you yet? Just in case no.... Well underground formations opposite of which the oil/gas well bore has been pierced usually flow naturally into the wellbore for recovery. Now the target reservoir's oil/gas flow potential is measured in two factors porosity and permeability (and actually the thickness of the source rock-but that is not relevant here). "Porosity" means how much oil/gas the little indentations in the source rock formation holds. "Permeability" refers to how well that trapped oil/gas may flow through the source rock formation and toward the wellbore for recovery. You need both porosity and permeability for a good well. Now companies that "frac" wells try to improve the permeability of the downhole formation usually in one of two ways: either flushing acids down the hole and into the formation in order to eat into the source rock and improve flow; or hydraulically-i.e. forcing water or a water /chemical/sand mix downhole and into the formation to fracture it through hydraulic pressure, witht he idea that oil/gas will flow toward the wellbore along these newly created cracks/channels in the source rock Fraccing may be done right after a well is drilled by the drill crew, or later in a well's life by a workover rig..... Sincerely, Doug F.
