 Kansas Geological Survey Open-file Report 2002-9 |
Wireline log water saturations were interpreted using the available resistivity logs and the Archie equation for water saturation calculations. Previous analysis of Morrow sandstones has shown that the cementation exponent, m=1.81, and intercept, a=1, for channel sandstones and m=2 and a=1, for other lithofacies (Figure). For the Morrow in the Minneola Unit, average m=1.78+0.09 for a=1 for the channel sands, or alternately, linear regression analysis of the trend indicates that m=1.74 and a=1.08. Other lithofacies exhibit an average m=2.
