  <dc:description>&lt;p&gt;In the southern part of the Piceance Creek basin the upper&amp;nbsp;part of the Green River Formation above the Mahogany zone contains&amp;nbsp;beds of rich oil shale which may be economically recoverable by a&amp;nbsp;surface-mining operation. Four units within this sequence were evaluated&amp;nbsp;for thickness, distribution, oil yield, and potential shale-oil&amp;nbsp;resources. In the area appraised, total estimated resources of 128.5&amp;nbsp;billion bbl of oil are contained within the sequence. It is thickest in&amp;nbsp;T. 3 S., R. 96 W., where 354 feet of oil shale yields an average of 14 gal&amp;nbsp;of oil per ton, with a total resource of 9.0 billion bbl. It is richest in&amp;nbsp;T. 5 S., R. 96 W., where 250 feet of oil shale yields an average of 19 gal&amp;nbsp;of oil per ton, with a total resource of 6.5 billion bbl. Resources are&amp;nbsp;tabulated for four units of the sequence.&lt;/p&gt;</dc:description>
