Schlumberger Ngi Tool [hot] Info

SLB (Schlumberger) NGI tool (Next Generation Imager) is a high-resolution borehole imaging tool designed to replace legacy systems like the Dual OBMI (Oil-Based Microimager). It is primarily used for formation evaluation in wells drilled with oil-based mud (OBM).

Best Practices

• Run complementary logs (caliper, density/porosity, sonic) to validate image interpretations.
• Use statistical fracture analysis (rose plots, spacing histograms) rather than relying on single picks.
• Cross-check image-derived stress indicators with independent stress-measurement methods when possible (e.g., mini-frac, DFIT).
• Schedule imaging runs in clean, stable borehole sections when possible; optimize mud type/viscosity and logging speed for best contact.
• Archive raw images and picks with metadata to support re-interpretation and machine-learning applications.

How does the NGI tool work?

1. Drill Bit
2. Schlumberger NGI Tool (Near-bit)
3. Mud Motor / RSS
4. Periscope (Deep Directional Resistivity)
5. EcoScope (Multi-function LWD)
6. Telemetry Module

The NGI tool solves this latency problem. By placing sensors within 4 to 10 feet of the bit, the NGI delivers "real-time zoning." When the bit crosses a formation boundary (e.g., from sandstone to shale), the NGI registers the gamma spike almost instantaneously. schlumberger ngi tool
