Micro-Spherical Logging Tool (MSFL)

GOWell’s MSFL tool provides a measurement of the flushed zone resistivity (Rxo) with single axis caliper, and/or dual axis caliper borehole diameter measurements. The Rxo measurement is used to calculate the flushed zone saturation, and correct other resistivity measurements to determine true formation resistivity (Rt). The XY caliper and MSFL sondes may be run separately or combined.
