The NGI tool detected a down-dip structural change that was not apparent on the seismic data. The inversion model showed the bit approaching the lower limestone boundary 12 feet early. The team steered aggressively up-hole, avoiding a trip out of the reservoir. Final well data showed 98% net-to-gross (NTG) in the target zone, delivering an IP (Initial Production) 40% above prognosis.
, which offers photorealistic reservoir imaging in oil-based muds. Real-world Use
Tx control for individual pads allows for real-time optimization in varying borehole conditions. schlumberger ngi tool
The NGI is a pad-mounted, high-frequency electromagnetic propagation tool. Key specifications:
The Schlumberger NGI tool has a range of applications across the oil and gas industry, including:
The Schlumberger NGI tool is an advanced induction logging instrument designed to measure the electrical resistivity of subsurface formations. Electrical resistivity is a foundational measurement in petrophysics; because hydrocarbons (oil and gas) are highly resistive while formation water is highly conductive, resistivity logs are essential for calculating fluid saturation and identifying commercial pay zones.

(Voltage Return, Amplitude, Frequency 1) for various pads and buttons. Applications in Formation Evaluation Thinly Bedded Reservoirs
At high frequencies (megahertz to gigahertz), the measured dielectric permittivity is dominated by the water volume, because water molecules have a permanent dipole moment that aligns with the alternating electric field. Gas and oil do not.
Many engineers confuse the NGI tool with its predecessors. Here is the differentiation: The team steered aggressively up-hole, avoiding a trip
High sampling rates enable the detection of features at the millimeter scale, crucial for fractured reservoirs. 4. Case Study: Carbonate Reservoir Characterization
