President's ColumnContinued from page 6rock(s) begat the accumulations (Higley and others,2009).In-place bitumen estimates for 29 majoraccumulations in Alabama, Alaska, California, Texas,Utah, and Wyoming is about 54 billion barrels (Schenkand others, 2006). In-place resources for two bitumenaccumulations in Wyoming total 120 million barrels (MB)measured and 70 MB speculative (IOCC, 1983; Schenkand others, 2006). Utah has the largest number of andtotal size of accumulations, which are located mainly inthe Uinta Basin of northeastern Utah (Blackett, 1996),and in central-southeastern Utah (http://geology.utah.gov/emp/tarsand/index.htm). Estimates of in-placeresources for Utah accumulations range from about11.9 BB measured and 6.8 BB speculative (IOCC, 1983)to 14-15 BB in place and 23-28 BB potential (Gwynn,2007; Gwynn and Hanson, 2009).ReferencesBlackett, R.
