Novel High Speed Telemetry System with Measurements Along the String Mitigate Drilling Risk and Improve Drilling Efficiency
Daan Veeningen, SPE
Introduction of the Broadband Network, addressing deepwater challenges
High speed telemetry to measure and control downhole operations improving drilling efficiency
Measurements all along the string to warn for developing trouble
Cases and conclusions
IntelliServ Broadband Network
57,600 bits/sec Simultaneous data High bandwidth High definition High Volume Real time
10 bits/sec Sequential data
Continuous bi-directionaldata transfer
Data transferred in 2-5 sec pulses
1) Armored coax cable
2) Induction coils
Because downhole signals are transmitted and evaluated as time-series measurements, they have to be measured quickly enough to ensure they can be accurately defined.
