Frequently Asked Questions

Q: What is the difference between the Wenner and Schlumberger arrays?

A: The Wenner array is a popular array used for resistivity measurements, while the Schlumberger array is a dipole-dipole array used for resistivity measurements. The Wenner array is typically used for shallow resistivity measurements, while the Schlumberger array is typically used for deeper resistivity measurements.

Q: What is the difference between resistivity only and resistivity with IP measurements?

A: Resistivity only measurements are made using the supported measurement arrays, while resistivity with IP measurements are made using the supported measurement arrays, along with IP measurements in terms of PFE, Chargeability in msec, or Phase in mrad. Resistivity with IP measurements provide a more comprehensive understanding of the subsurface, including both resistivity and IP properties.

Q: How do I configure the measurement configuration?

A: To configure the measurement configuration, select the frequency range, coil spacing, and instrument height from the available options. The frequency range should be selected based on the type of measurement being made, while the coil spacing and instrument height should be selected based on the specific requirements of the measurement.

Q: What is the difference between horizontal coplanar, vertical coplanar, and vertical coaxial frequency-domain electromagnetic measurements?

A: Horizontal coplanar frequency-domain electromagnetic measurements are made using a horizontal coil configuration, while vertical coplanar frequency-domain electromagnetic measurements are made using a vertical coil configuration. Vertical coaxial frequency-domain electromagnetic measurements are made using a coaxial coil configuration. Each type of measurement has its own unique characteristics and applications.

Q: How do I invert the data using the IX1D program?

A: To invert the data using the IX1D program, select the inversion algorithm and parameters from the available options. The inversion algorithm should be selected based on the type of measurement being made, while the parameters should be selected based on the specific requirements of the measurement.
