Tubular strings in oil and gas wells are the backbone and central nervous system of oil and
gas drilling and production operations. Tubular mechanics in oil and gas wells is the most …

Notwithstanding the presence of some books summarizing specific research bodies on
structural systems, reviews on nonlinear dynamics and chaos in mechanical systems and …

In this paper, a dynamical model of simply-supported spinning pipes conveying fluid with
axial deployment is proposed and the transverse free vibration and stability for such a …

A full-coupled three-dimensional dynamic model of a towed cable body system is
developed. The towed cable with the axial elasticity, bending stiffness, and torsional stiffness …

Nowadays, drill string technologies are among the leading fields in the industries of oil and
gas extraction and are widely used in the construction of subway tunnels. Due to their …

This work intends to analyze the nonlinear stochastic dynamics of drillstrings in horizontal
configuration. For this purpose, it considers a beam theory, with effects of rotatory inertia and …

The response of the drilling system to axial and torsional vibration inputs has a significant
impact on drilling performance. Usually the goal is to minimize dynamic response to limit the …

In this paper we propose a new model for a spinning beam under deployment and present
analyses of the beam's dynamic responses and characteristics. The proposed model is …

As well designs become increasingly complicated, a complete understanding of drillstring
vibrations is key to maximize drilling efficiency and reduce bit wear as well as prevent …

Drilling technologies are widely used in the gas and oil extraction. Nowadays for further
extraction, horizontal drillings are more popular than vertical drillings. One of the main …
