PathFinder Resistivity Services

Array wave resistivity

The PathFinder AWR array wave resistivity tool uses dual frequencies to provide up to 12 resistivity curves in all mud types. It has 12 diameters of investigation with three sensors at spacings of 15, 25, and 45 in. The spacings are optimized to provide robust quantitative data for invasion corrections and processing without dielectric assumptions or single-frequency results.

Compensated wave resistivity

The PathFinder CWR compensated wave resistivity tool offers four resistivity curves (two phase and two attenuation) and symmetrical receiver spacings at 25 and 55 in for maximum depth of investigation. The balanced transmitter-receiver array provides repeatable measurements that are less susceptible to measurement noise induced by borehole rugosity and washouts, making accurate resistivity much easier to determine. PathFinder CWR measurements are made well beyond the invaded zone to give quick and accurate readings through porous and permeable lithology.

Slim compensated wave resistivity

For holes as small as 5 5/8 in, the PathFinder SCWR slim compensated wave resistivity tool supplies the same high-quality resistivity measurement as the PathFinder CWR tool, but with a limber design in a 4 3/4-in collar. The PathFinder SCWR tool resolves beds as thin as 6 in and directly measures resistivity in beds thicker than 4 ft. It can slide through 34°/100 ft curves and can be rotated through 17°/100 ft.
