Abstract: Sinusoidal buckling of drill strings will be easily caused during drilling process of extended-reach horizontal wells due to the factors such as excessive well length and larger friction torque, which will cause measurement errors of… read more here.

DOI: 10.1109/lwc.2017.2737619
Abstract: Wireless communication of information in oil wells is a key component of drilling operations. For cost-effective, fast, and low-risk drilling, information such as temperature, pressure, etc., should be transmitted from downhole to the driller on… read more here.

DOI: 10.1177/10812865231166129
Abstract: The classical lateral buckling of a straight drill string confined within an inclined cylindrical borehole is formulated as a singularly perturbed boundary-value problem which is subsequently explored using asymptotic techniques. In particular, the localised nature… read more here.
