Figure 99. Dual induction-SFL* with spontaneous potential log and R,,/R, curve, Devonian Hunton Delomite, Anadarko basin.
Note:
1. From 16,300 to 16,390 ft, the deflection of the R,,,/R, curve to the right away from the SP curve in track #1
which indicates the presence of hydrocarbons (see Chapter VD.
2. From 16.325 to 16.370 ft, see the much lower resistivities in tracks #2 and #3. This is the result of either a
water productive zone or a substantial change in the type of carbonate porosity (see Chapter V1, Table 8).
