N-S Seismic Line in Hancock Co.
• Thickest development of sandstone (estimated 589 feet) is likely below the proposed drill location (updated from values provided 2/7/08)
• Possible sand-rich facies below in pC1*--could represent reservoir rock (likely sedimentary, but not previously drilled)
• Mt Simon downlaps and changes facies to south—from sandstone to interbedded rocks (shales and sandstones ?)—formation pinches out to south
