The rock unit intervals correlated in this cross section Formation level are described in the accompanying report. Correlations represent interpretations of approximate depths and thicknesses of the units based on available data. Actual Member and bed level depths-11000 and thicknesses may vary, especially in faulted Precambrian areas. It is also important to understand that an interval basement Undiscussed described as a potential saline reservoir will not have correlation characteristics that allow injection and carbon storage across the entire thickness shown. Potential storage Faults will only be possible in much smaller zones of those intervals, as discussed in the accompanying report.
