Mud Pulse Telemetry (MPT)
Principle
Pressure builds by reducing flow cross-section
– Mud pulse travels to surface
– Propagation speed approx. 1200 - 1500m/sec
Pressure fluctuation detected on surface– transducer installed in standpipe

Baker Hughes Overall Approach to MPT
Data rates up to40 bps
![Page 9: FESAus – New Technology Forumfesaus.org/webcast/2012/09/NTF/7_aXcelerate_MWD... · 2018. 2. 2. · Baker Hughes Drilling & Evaluation aXcelerate™- High-Speed Telemetry Martin](https://reader035.vdocument.in/reader035/viewer/2022071500/611e8b5179440d6d5310bf05/html5/thumbnails/9.jpg)
Baker Hughes Approach to MPT (BCPM 1)
Action: Poppet Valve reciprocating
Data rates up to 10bps (offshore Australia, commonly
4-6bps is expected without decoding issues)
Parameters fully adjustable via downlinks
Telemetry system limitation is the PoppetValve (relaxation time of the MVA body)

BCPM2 Summary
Increased RT data density allowing for either:
i. Increased ROP
ii. More data RT
Reduced drilling risk due to a clearer picture of down-holedynamics
Improved tolerance against LCM plugging – less NPT
Greater flexibility on decoding issues
