Soft Decision Decoding in Mud Pulse Telemetry System
2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring), 2020 In this paper, we propose a new probabilistic decoding method for the measurement-while-drilling telemetry system. The mud pulse telemetry system transmits the data from inside a borehole to the surface during drilling operations. The mud pulser is equipped with a mechanical valve, which partly shuts the mud stream for a short time, realizing ...

Evolution in Reliability of High-Speed Mud Pulse Telemetry
Offshore Technology Conference, 2016 Mud pulse telemetry (MPT) is the leading real-time data transmission technology in the oil industry to deliver answers while drilling. New logging-while-drilling (LWD) tools produce increasing amounts of data that has to be transmitted to the surface. To avoid a compromise between rate of penetration (ROP) and log density, the real-time

Field Performance of Automated High-Speed Mud Pulse Telemetry System
IADC/SPE Drilling Conference and Exhibition, 2016 AbstractPresent logging-while-drilling (LWD) technologies have substantially increased the amount of information collected downhole. Mud pulse telemetry (MPT) is the core real-time data transmission technology in the oil industry, and it must deliver answers while drilling with equal log densities despite the increased number of services.
