Schlumberger Ngi Tool Guide

: Identifies natural and induced fractures, hard streaks, and stratigraphic features that are otherwise invisible in OBM systems. Core Calibration

The NGI is typically run as part of an integrated wireline logging platform, such as the Platform Express

: The tool has been deployed globally, including a notable 2,000-meter interval acquisition in Australia's North Carnarvon Basin to support reservoir quality assessment. compares to newer tools like Quanta Geo at-bit imaging service?

The tool’s architecture is deceptively simple but exceptionally powerful. It houses two primary sensors:

Thus, the NGI can compute independently of salinity. : Identifies natural and induced fractures, hard streaks,

The is a sophisticated wireline logging tool designed for high-resolution microresistivity imaging of the borehole wall. It is part of the next generation of formation imaging devices that provide precise structural and stratigraphic data.

The tool transmits electromagnetic waves from one antenna to a receiver. By comparing the and attenuation between receivers, the complex dielectric permittivity (( \varepsilon^* = \varepsilon' - j\varepsilon'' )) is derived. Microresistivity - Oil-Based Microimaging | SLB The tool’s

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:
