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

Research on signal processing of continuous wave mud pulse

2011 Second International Conference on Mechanic Automation and Control Engineering, 2011
The system of continuous wave mud pulse measurement is important for oilfield directional drilling well. The signal processing is one of the key technologies to the system of mud pulse measurement, however, it is difficult to acquire the useful signals, since including most of reflective and mud pump noises. Based on the signal's characteristic of sine,

Simulated Study for OOK Modulation in the Mud Pulse Telemetry

Applied Mechanics and Materials, 2015
Mud pulse telemetry (MPT) transmits data from borehole to surface during the drilling process. Pressure wave is generated in the drilling channel and is used as carrier of the downhole data. Through numerical simulation, this paper analyzes the bit error rate (BER) of mud pulse telemetry under different signal to noise ratio (SNR) based on on-off ...

Understand the Effect of Mud Pulse on Drilling Dynamics Using Big Data and Numerical Modeling

Day 3 Thu, September 23, 2021, 2021
It is common to have measured depth exceeding 20,000 ft for unconventional oil and gas wells. To ensure the pressure pulse can be detected on the surface, many MWD tools have been designed to generate mud pressure pulse with very large amplitude. While

Long-term in situ observations at the Athina mud volcano, Eastern Mediterranean: Taking the pulse of mud volcanism

Tectonophysics, 2017
Abstract Long-term monitoring on mud volcanoes is fundamental to unravel episodic processes and transient changes that might otherwise be missed by using snapshot observations during time-limited research expeditions. We deployed a pore- and seafloor-pressure observatory close to the main conduit of the Athina mud volcano, south of Turkey (Eastern ...
