AmerAlia. Inc <br />LI~I'llOLOGl <br />MWU-2 Dnlhng and CompleUOn Report <br />Cuttings samples were described for the interval from 635 [o GR7 feet (Table 3 ). Analysis of <br />these cuttings indicates that 1-our major lithologies exist in the penetrated interval of IviR'l i-~: <br />1. Sandstone and silty sandstone. <br />2. siltstonc :utd sandy siltstonc. <br />3. Carbonate-rich marlstone (< 3 gallons per tun [gpt]). <br />~. Carbonate•rich oil shale (> 3 gpt). <br />Sandstone and siltstonc ~vnplcs arc most common at depths shallower than G00 feet. whereas <br />marlstone and Ivan oil shale are the dominant samples below G00 feet.
