QL40-ELOG
from Mt Sopris

The QL40ELOG multi-point resistivity probe sub can be run stand-alone or with other QL tools in a custom stack. Measurements include 8, 16, 32, and 64-inch (0.2, 0.4, 0.8, 1.6 meter) normal resistivity, single point resistance (SPR), and self-potential (SP). Other QL probes commonly stacked with the QL40ELOG include the QL40GR (natural gamma), QL40FTC-B (temperature0fluid resistivity), and the QL40CAL (3-arm caliper), but many possibilities exist owning to the flexibility of the QL (Quick Link) family. Normal resistivity measurements, single point resistance, and self-potential measurements are designed for surveying open (uncased) fluid filled boreholes.
