(Voltage Return, Amplitude, Frequency 1) for various pads and buttons. Applications in Formation Evaluation Thinly Bedded Reservoirs
: Helping distinguish between sand and shale in complex, thinly bedded reservoirs. Wellbore Stability schlumberger ngi tool
By the early 2000s, the NGI was largely by more advanced tools: the HNGS for hostile environments, the Elemental Capture Spectroscopy (ECS) tool for detailed mineralogy, and later the LithoScanner platform. (Voltage Return, Amplitude, Frequency 1) for various pads
:
: The tool’s software automatically compensates for the "signal noise" caused by the borehole size, mud type, and the "skin effect" (electromagnetic interference). Key Benefits for Reservoir Analysis schlumberger ngi tool
