Improvement of friction estimation along wellbores using multi-scale smoothing of trajectories
European Journal of Computational Mechanics
Drilling monitoring aims at anticipating and detecting any drill string failures during well construction. A key element for the monitoring activity is the estimation of friction along the wellbore trajectory. Friction models require the evaluation of the actual wellbore trajectory. This evaluation is performed applying any of various reconstruction methods available in the industry to discrete deviation measurements. Although all these methods lead to nearly identical bit location, frictiondoi:10.13052/ejcm1958-5829.2834 fatcat:yghe7gbifrhr3ljynaayg744ye
