Dynamic Invasion Correction Charts for Dual-Induction Logs

Commercial induction tools consist of multiple coil arrays designed to optimize vertical resolution and depth of investigation. However, to illustrate induction-tool fundamentals, it is instructive to first examine the basic building block of multiple-coil arrays, the two-coil sonde. Fig. 1shows that a two-coil sonde … See more To produce adequate sensitivity to the uninvaded zone, induction tools perforce include signals from a large volume of formation. The challenge is to determine exactly where the … See more Because the direct transmitter-receiver mutual coupling of a two-coil array can produce a voltage several thousand times that from a formation, two-coil arrays are not practical. The … See more The DIT tool became the standard resistivity tool and remained virtually unchanged for more than 20 years. However, as its … See more One of the challenges of measuring formation resistivity is to sort out the resistivity of the invaded zone from that of the virgin zone.
