Schlumberger Ngi Tool ((new)) Link

| Parameter | Value | |-----------|-------| | Frequencies | Dual-frequency (e.g., 100 MHz & 1 GHz) | | Depth of Investigation | Shallow (~1–2 inches, primarily flushed zone) | | Vertical Resolution | ~1 inch (25.4 mm) | | Measurement principle | Phase shift & attenuation | | Tool configuration | Hydraulically actuated pad (like FMI or micro-resistivity imagers) |

Whether you are landing a horizontal well in the Eagle Ford, drilling a high-angle appraisal well offshore Angola, or simply trying to avoid a water leg in a mature field, the NGI remains the unsung hero of the bottom hole assembly. It answers the two most important questions a driller can ask: "Where am I?" and "What am I in?"

The represents a major engineering leap in openhole wireline formation evaluation . Developed by SLB (formerly Schlumberger) to deliver photorealistic, core-like structural and stratigraphic imaging, the NGI architecture enables precise downhole microresistivity tracking in challenging borehole environments. By utilizing sophisticated impedance measurements and highly articulated sensor pads, this system captures unmatched, high-definition data used to map fractures, define thin beds, and build accurate reservoir models. 🛠️ Technical Specifications and Measurement Physics schlumberger ngi tool

The Schlumberger NGI tool is equipped with a range of sensors and detectors that enable it to collect a diverse set of measurements. These include:

The NGI tool incorporates several mechanical and electronic enhancements over previous generations: Sensor Configuration: | Parameter | Value | |-----------|-------| | Frequencies

: Traditional electrical imaging tools often fail in nonconductive muds because the mud acts as an insulator. The NGI tool overcomes this by using frequencies and electrode configurations that can "see through" the oil film on the borehole wall. Key Applications Formation Evaluation

Carbonate reservoirs often present technical difficulties for logging while drilling (LWD) and traditional wireline tools. In this study, NGI data was integrated with: The NGI tool overcomes this by using frequencies

. This wireline tool is a high-resolution borehole imaging system designed to provide 360-degree coverage of the borehole wall in various mud types, including oil-based and water-based systems.

Raw analog signals from the receiver coils are digitized immediately within the tool. Advanced mathematical algorithms process these signals in real-time, stripping out environmental noise and borehole skin effects before sending the data to the surface. Key Benefits of the NGI Tool

The NGI tool is primarily deployed for:
