The logs in [[:file:standard-interpretation_fig3.png|Figures 3]] and [[:file:standard-interpretation_fig4.png|4]] are used for this example. [[:file:standard-interpretation_fig3.png|Figure 3]] is a deep induction log recorded with a shallow resistivity device and SP, while [[:file:standard-interpretation_fig4.png|Figure 4]] is a compensated density-neutron log with a gamma ray. The well is an unconsolidated sand and shale sequence from the Gulf Coast area. Interval D is apparently wet because of the low resistivity. ''R''<sub>w</sub> can be determined in this interval from either the SP or by the Archie method (see [[Determination of water resistivity]]). ''R''<sub>w</sub> was determined here by the Archie method to be 0.026 Q-m at formation temperature. For the purposes of this example, no environmental corrections were made and were assumed to be unnecessary.
