CWR™ Compensated Wave Resistivity
2 MHz Compensated Wave Resistivity
PathFinder’s CWR™ tools offer the greatest diameter of investigation of any 2 MHz resistivity tool in the industry! It provides 4 resistivity curves (2 phase and 2 attenuation) with symmetrical receiver spacing at 25” and 55” for maximum depth of investigation. Since the transmitter-receiver array is balanced, it provides repeatable measurements that are less susceptible to the noise induced by borehole rugosity and washouts which makes Rt much easier to determine accurately. The CWR’s measurements will be made well beyond the invaded zone to give quick and accurate readings through porous and permeable lithology.
Data processing algorithms have been developed than can enhance the functionality of resistivity profiles normally encountered in shallow well environments with corrections thin beds, high dielectric constants and anisotropy.
The CWR™ tool is available in nominal collar sizes from 4 ¾” to 9 ½” for hole sizes ranging from 5 7/8” to 26”.
