Mud Pulse Signal Extraction and Noise Cancellation based on Adaptive LMS and NLMS Algorithms Performance

Mwachaka, Saleh M. (International Journal of Engineering Research & Technology (IJERT), 2020-05-05)

During logging-while drilling data collection and transmission, strong noise and interferential signals contaminate mud pulse encoded signals. Varying and unpredictable statistical noise characteristics severely influence ...
A Novel Weak Signal Detection Method of Electromagnetic LWD Based on a Duffing Oscillator

Wu, Aiping; Mwachaka, Saleh M.; Pei, Yanliang; Fu, Qingqing (Journal of Sensors, 2018-06-21)

Numerical modeling of electromagnetic wave logging while drilling in deviated well

Wu, Aiping; Fu, Qingqing; Mwachaka, Saleh M.; He, Xiaoying (Journal of Ambient Intelligence and Humanized Computing, 2018)

Electromagnetic wave logging-while-drilling (LWD) tools are used in geosteering for hydrocarbon exploration. Comparing with vertical wells, the response of logging has widely changed because the electrical parameters ...
A review of mud pulse telemetry signal impairments modeling and suppression methods

Mwachaka, Saleh M.; Wu, Aiping; Fu, Qingqing (Journal of Petroleum Exploration and Production Technology, 2018-06-02)

Exploration and drilling operations are the most costly and risky activities that require logging while drilling effective tool operation and high speed real-time data transmission. Among other logging technologies, mud ...
