Down-hole tubular string buckling is the most classic and complex part of tubular string
mechanics in well engineering. Studies of down-hole tubular string buckling not only have …

Well interventions in long lateral-reach wells, ie, wells with laterals 10,000-ft or longer,
continues to challenge the oil and gas industry around the world. Without specialized friction …

A comprehensive buckling model, a group of fourth-order nonlinear ordinary differential
equations, was derived by applying the principle of virtual work. Lateral friction force is …

We investigate the buckling and post-buckling behavior of an elastic rod injected into a
horizontal, frictional, cylindrical constraint through experiments, numerical simulations, and …

Horizontal well is one of the main measures to improve oil and gas production capacity.
However, with the extension of horizontal section, the risk of pipe string buckling will be …

Understanding the buckling behaviors of rods confined in a finite space is of paramount
importance in a diversity of engineering fields. In this paper, theoretical analyses, numerical …

With the growth of oil and gas resource demand, the hydro-oscillator is widely used to
enhance the Rate of penetration (ROP) and improve the efficacy in drilling various wells …

Well intervention in long lateral-reach wells, ie, wells with laterals 10,000-ft or longer, is
predicted to become more common within the current low price oil environment. During …

Research on down-hole tubular mechanics has been more than 70 years so far. Many
breakthrough research results have been obtained, and they have been successfully …

We present results from an experimental and numerical investigation on the compression,
and consequent buckling, of a slender rod constrained inside a horizontal cylinder. An …
