COMPASS Azimuthal Gamma ModulE
Reduce uncertainty with the Compass Azimuthal Gamma Module and easily distinguish between formation layers with low gamma ray content. This highly accurate azimuthal gamma ray LWD tool measures gamma rays from 4 quadrants in the formations adjacent to the wellbore and is ideal for Gamma Ray imaging in real-time and recorded mode.
Compass Azimuthal Gamma Module has a 3-axis Vibration sensor to optimize drilling by logging vibration data. Four scintillation detectors spaced 90° apart allow for gamma-ray imaging that places wells accurately and maximizes reservoir contact with a clear view of the surrounding geology. Operators can makegeo-steering decisions with greater confidence.
Geological and petrophysical applications
- Place wells accurately and maximize reservoir contact with a clear view of the surrounding geology while in rotating or sliding mode
- Target zone can be precisely identified based on the superior gamma ray images
- Capable to optimize the stratigraphic placement of laterals
- Determine shale volume
- Very helpful to pick accurate casing and coring point by determining formation tops
