Calibrated Resistivity Check Plugs
Calibrated Resistivity Check Plugs LECERC are a set of two stainless steel reference plugs used to verify and test the calibration of a resistivity meter. The two plugs have different known resistances, 10 ohms and 1,000 ohms, stated to an accuracy of 0.1%. They are used alongside formation factor and resistivity index measurements, where the meter reading feeds Archie-based log analysis.
How it works
The plugs are made in core plug dimensions: 3.0 inches long, with diameters of 1.0 inch, 1.5 inch, 30 mm or 50 mm. The operator loads a plug in the sample position, reads its resistance on the meter and compares the reading with the calibrated value. Because the two values are two orders of magnitude apart, the check covers a low and a high point of the meter range.
A reading outside the stated accuracy points to the meter, electrodes or wiring, and the fault is corrected before rock samples are measured. Repeating the check at intervals gives a record that the measurement chain has not drifted.
