An Experimental Setup to Measure the Conductivity of a Solid or Liquid Sample Utilizing Multi-Frequency LCR Meter

Shahryar Darayan Department of Engineering Technologies Texas Southern University

Abstract

A computer-controlled automated data acquisition system is designed to measure the conductivity of the liquid (saline water) or the solid sample (rock saturated with saline water) in the frequency range 10 kHz to 2 MHz. The set-up is based on LCR (Inductor, Capacitor, and Resistor) multimeter and four-terminal sample holder system that was developed to reduce the contact resistance, to minimize any stray capacitance, and residual inductance associated with the test leads or the test fixture at high frequencies. However, the instrumentation calibration scheme cannot completely eliminate the aforementioned errors. In order to accomplish this, a calibration model is designed to compensate for the inherent error of the system. In this study, the conductivity of some samples was measured. The measured data was compared with conductivity provided by Society of Core Analysis Guideline (SCA-GL). The agreement between available data and experimental data is excellent.

Introduction

The increased ability of those in the petroleum industry to analyzed the formation characteristics from electrical resistivity data, it is imperative to have more precise method to measure that parameter 1,2.

Several types of resistivity sensors are available on MWD (Measurement-While-Drilling) tools. The earlier ones were short normal sensors operating near DC (Direct Current)3, 4, 5 and coil-type sensor operating at 2 MHz 6, 7, 8. For instance, the coil-type MWD resistivity tool measures phase and attenuation. Then, some conversion algorithms are used to transform the measured quantities in terms of apparent resistivities. In this conversion, the formation dielectric constant is assumed to be either a constant value or a known function of the resistivity which is not a correct assumption. Therefore, it is a common practice to obtain some samples from the core selected reservoir and then an actual electric permittivity are measured in the core measurement facility.
