AmerAlia, Inc. <br />MWD-1 Drilling and Completion Report <br />Although cuttings were only collected and described between 950 and 1,731 feet (TD) in <br />MWD-1, a good understanding of the total lithologic variability of the stratigraphic section in <br />this well can be obtained by use of cutting descriptions from wells MWA-2 (cuttings were <br />described from the surface to 1,198 feet) and MWB-2 (cuttings were described from 1,095 to <br />1,398 feet), which aze located on Drill Pad 2 approximately 420 feet northeast of MWD-1. T'he <br />composite data from MWA-2, MWB-2, and MWD-1 show that five major lithologies exist <br />between the surface and 1,731 feet (L-5 Zone). <br />Litholo¢v Dominant Stratigraphic Occurrence <br />Sandstone and Surface colluvium and Uinta-Green River transition <br />Silty Sandstone zone. <br />2 <br />Siltstone and Sandy Uinta-Green River transition zone, and the A- and B- <br />Siltstone Grooves of the Parachute Creek Member. <br />3. Cazbonate-rich Uinta-Green River transition zone, and the R-8 Zone, <br />Marlstone A-Groove, Mahogany Zone, B-Groove, and L-5 Zone <br />(< 3 gallons/ton [gpt]) of the Pazachute Creek Member. <br />4. Cazbonate-rich Uinta-Green River transition zone, and the R-8 Zone, <br />Oil Shale (? 3 gpt) A-Groove, Mahogany Zone, B-Groove, R-6 Zone, and <br />L-5 Zone of the Parachute Creek Member. <br />5. Volcanic tuff {deposited R-8 and Mahogany Zones of Parachute Creek Member. <br />in water) <br />A graphic summary of gross lithology variations in MWD-1 between 950 and 1,731 feet is <br />shown in Figure 6, which is based on data from Table 5. For this figure, Lithology 5 (volcanic <br />tuff) is not included because this rock type makes up only trace amounts of the total stratigraphic <br />section. Also shown on Figure 6 are estimated oil-content (gpt) values, as defined by the general <br />color of the rotary drill cuttings (shades of dazkness between light brown, gray, dazk brown and <br />black). Light-colored cuttings have lower kerogen contents than those with darker hues. <br />Estimated shale-oil data also aze included in Table 5. <br />4 <br />
