Dynamic Analysis and Vibration of Beam Inside Annulus for Ultra Short-Radius Water Jet Drilling

Tasneem Pervez, Saif A. Al-Hiddabi, Amer S. Al-Yahmadi et al. · The Journal of Engineering Research · 2012 · 10.24200/tjer.vol9iss1pp55-63

Conventional water-jet nozzle systems have been developed and partially used in the oil and gas industry to drill horizontal sidetracks. However, this technique still presents a few shortcomings associated with tube buckling and water jet sagging. Due to these problems, the drilled hole deviates from the desired path a …
