Dual Spaced Focused Resistivity Tool

The Dual Spaced Focused Resistivity Tool is an advanced instrument designed to measure the resistivity of materials surrounding the borehole. With finer vertical resolution and deeper depth of investigation compared to normal resistivity tools, this instrument excels in providing detailed subsurface resistivity data.

The tool performs exceptionally well in environments with high conductivity mud, saline water, and high-resistivity formations. Resistivity readings are influenced by porosity, mineralogy, and pore water quality, making the tool ideal for geological and hydrogeological investigations. Additionally, in metal-lined boreholes, the tool can provide qualitative information on casing conditions, identifying areas of increased corrosion or encrustation.
