QL40-IND – Dual Induction

Q40-IND-Header-Image

Description

The QL40-IND Dual Focused Induction probe provides two simultaneous conductivity logs, corresponding to “Medium” and “Deep” radii of investigation into the borehole. The two depths of penetration are useful in porous, permeable formations where displacement of formation fluids by drilling mud creates an invasion zone with different electrical properties.

High stability and exceptionally wide dynamic range allow the user to carry out precise measurements of conductivity in formations with sand-clay layers and mineralized, water-soaked sands. In contrast to electrical tools, this induction tool can be used in dry and non-metallic cased holes.

The QL40-IND tool is stackable within the Quick Link (QL) product line or it can be run as a standalone tool.
