WebThe Dual Induction Log provides four measurements: Deep and Medium Induction curve, Shallow Focused Laterolog and a Spontaneous Potential curve. It is suitable in high-resistive mud systems. 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, … 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. The … See more chris cousin physio

For example, Figure 1 is a flowchart illustrating the steps used to determine true resistivity from a dual induction log. It should be noted that shoulder bed effect corrections are difficult and require complex algorithms. Web19.5.2 The Dual Laterolog The dual laterolog (DLL) is the latest version of the laterolog. As its name implies, it is a combination of two tools, and can be run in a deep penetration … Webdata. Compensated Density Log-Neutron provided also gamma ray, caliper, and density correction (Ap) curves. Compensated Acoustic Velocity Log also presented self potential, caliper and time depth integrator data, Dual Induction Guard Log provided self potential along with deep induction, medium induction, and shallow guard logs.
