Dave Cohen on Tuesday September 05, 2006 at 11:04 AM EST These lower Tertiary reservoirs were first identified in the 1930's. Technology prevented drilling any test wells until now. Another well will be drilled in 2007. If things go right and the price stays high -- it will, unless there's a world wide recession -- full-scale production would begin in 2013. Assuming a 5% global decline rate (this is a standard number) and an optimistic daily flow from these GOM reservoirs of 200/kbd in 2013 -- well, you do the math, OK? It's time to make different arrangements for how we live, not engage in cable news-style cheerleading. As Jeffrey says below, in a Hubbert linearization or production curve (same thing, just an easy transform), this is merely an indiscernible bump (depending on the graph scale) in the long tail end of US production. I see we need another "Guide for the Perplexed" here. ======= westexas on Tuesday September 05, 2006 at 10:49 AM EST "In other words, are these extra 5 to 30 billion barrels already part of that cumulative 228 billion barrels, or do you add them to the 228 billion?" The question partly turns on how you define "conventional." A lot of people don't define ultra deep water production as conventional. My personal definition of conventional is that it is oil that will move to a wellbore without having to add heat energy to the system and/or that you don't have to stripmine. The best way to answer the question is that we are not going to see any region show a perfectly straight line down to where the plot intersects the horizontal axis (where P = zero), because a lot of these regions will virtually never stop producing. Inevitably, what we will see is a long production "tail" which on a HL plot, will show up as the data plot asymptotically approaching the horizontal axis, without ever quite getting there. As I pointed out above, what this fundamentally points out is the difference between the fortunes of the energy producers and the energy consumers. If Matt Simmons is right about oil prices ($200 per barrel in 2010, in constant 2005 dollars), every one million barrel oil field that one finds (or redevelops with more advanced recovery techniques) onshore in the Lower 48 will generate cash flows of up to $150 million or so (depending on the royalty and operating costs). In many areas, a one million barrel field can be found in an area as small as 100 acres. If you string together seven small fields like this, you have a billion dollars in net cash flow. The point is that neither these "leftover" Lower 48 fields nor these ultra deep offshore discoveries will do anything to change the fundamental reality of Peak Oil. Both may be profitable, but we are just working the "tail" at the end of the production rate versus time plot.
