Multi-Array Induction Tool

Multi-Array Induction Tool uses multi-spacing and multi-frequency measurements to acquire a complete set of data from the formation. The tool acquires formations resistivity from different investigation depths.
Multi-Array Induction Tool is equipped with eight groups of receiving coils, which acquire twenty-eight raw logging data in three frequencies. After correction and self-adapting software focusing processing, the logging data are converted to fifteen curves with three vertical resolutions and five radial investigation depths. The minimum vertical resolution is 11.81 in (30cm); the maximum investigation depth is 88.58 in (225cm).
Multi-Array Induction Tool is an important logging tool for oil/water differentiation and oil saturation evaluation.
The resistivity curves with high vertical resolution are essential in laminated sand/shale reservoirs for thin layer delineation and oil saturation calculation.
The resistivity curves with five radial investigation depths can be further processed to present invasion profile image or oil/water saturation profile image, which presents a clear picture for invasion and oil/water zone identification.
Multi-Array Induction Tool can work in water-based mud, oil-based mud or air filled borehole.
