Wireline Resistivity Logging Services

Two categories of resistivity logs are: induction and laterolog. The laterolog tools use electrodes to inject a current on the formation and to measures voltages at different points in the tool.

The induction tools use coils and magnetic fields to develop currents in the formation whose intensity is proportional to the conductivity of the formation.

The intensity of these currents is measured on receiver coils in the tool. Halliburton provides offerings of both types.




Dual Laterolog (DLLSM) Formation Resistivity Log Service
Wireline service that measures the resistivity of a volume of formation close to the borehole (shallow resistivity) and the resistivity far from the borehole (deep resistivity).
Hostile Array Compensated True Resistivity (H-ACRt™) Tool
Rated to 500°F and 30,000 PSI. Wireline induction tool that consists of a single transmitter operating at three frequencies and six receiver antennas with spacing from 6 to 80 inches. It gives resistivity values at 5 different depths of investigation and with the same vertical resolution (either 1, 2, 4 ft).
Micro-Spherically Focused Log (MSFL®) and Microlog (ML)
Wireline tool developed to eliminate borehole effects and achieve superior shallow investigation; provides two resistivity and caliper measurements.
The ACRt™ array compensated resistivity tool system
The ACRt™ array compensated resistivity tool system represents the latest thinking in conventional array induction technology
Xaminer™ - MCIT
Halliburton’s Xaminer™ Multicomponent Induction (MCI) tool enables the evaluation of anisotropic formations by measuring the formation resistivity both vertically and horizontally at differentdepths of investigation.
