Near-bit Measurement System
Features and benefits.
- The module is integrated with the existing MWD systems LHE630N and LHE650N
- Communication between transmitter and receiver is carried out through wireless communication channel in all types of solutions
- Independent power supply
- Measurement of curvature near the drill bit
- Lithologic sectional layering
- Binding in the geological section
- To the feedback module for 2 sectors in real time (Top/Bottom). Data from the memory module represented by the responses in 8 sectors.
- Geosteering
