It is often run as part of the or Sonic Scanner tool strings.
But what exactly is the NGI tool? Why has it become a critical component of modern geosteering and reservoir characterization? This article provides a deep dive into the technology, applications, and operational benefits of the Schlumberger Near-bit Gamma and Inclination (NGI) tool. schlumberger ngi tool
Its primary purpose is to determine:
: 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 It is often run as part of the or Sonic Scanner tool strings
The is a high-resolution, multi-detector spectral gamma ray tool. Unlike a standard total gamma ray tool (which simply counts all gamma rays), the NGI measures both the total count and the energy spectrum of naturally occurring gamma rays. This article provides a deep dive into the
The NGI tool is most commonly deployed in production logging and well integrity surveys:
