Array Laterolog Tool (ALAT)
Reliable resistivity profiling in conductive borehole fluids
Our Array Laterolog Tool provides a reliable resistivity profile in conductive borehole fluids using five borehole-corrected resistivity curves at increasing depths of invasion. The service enables the visualization of invasion and the measurement of true formation resistivity (Rt).
Not affected by the borehole, invasion, or shoulders, Rt is obtained by inverting the measured resistivity curves using a step-invasion profile model. This also provides resistivity in the flushed zone Rxo and the diameter of invasion.
Our service offers resistivity measurements up to 100,000 Ω-m and in a wide range of mud systems resistivities (from 0.02 to 2 Ω-m).
