Schlumberger Ngi Tool Jun 2026

: Capable of operating at multiple frequencies (e.g., Frequency 1 and Frequency 2) to capture varied impedance data, which is essential for characterizing different formation types.

| Application | How NGI Helps | |-------------|----------------| | | Corrects for non-clay radioactivity (e.g., K-feldspar, mica) | | Source rock identification | High Uranium indicates organic matter | | Clay typing | Th/K ratio distinguishes swelling vs. non-swelling clays | | Unconformity detection | Uranium enrichment below unconformities | | Heavy mineral zones | Thorium peaks (monazite, zircon) | | Borehole environmental correction | Uses near/far ratio to correct for mud weight, standoff | schlumberger ngi tool

Conventional resistivity tools often fail to detect gas in certain formations due to: : Capable of operating at multiple frequencies (e

: It operates by measuring voltage returns, amplitude, and phase across different frequencies to deliver real-time, high-resolution full-azimuth coverage of the wellbore. Applications in Field Development high-resolution full-azimuth coverage of the wellbore.

Traditional micro-resistivity imagers often struggle in oil-based mud because the oil acts as an insulator; the NGI overcomes this by using a high-frequency alternating current and capacitive coupling to inject signals through the nonconductive mud and into the formation.
