Biocide-mediated corrosion of coiled tubing [PDF]
PLOS ONE, 2017 Coiled tubing corrosion was investigated for 16 field water samples (S5 to S20) from a Canadian shale gas field. Weight loss corrosion rates of carbon steel beads incubated with these field water samples averaged 0.2 mm/yr, but injection water sample S19 had 1.25±0.07 mm/yr.

Analysis of sinusoidal post-buckling deformation of horizontal coiled tubing with initial residual bending. [PDF]
PLoS ONEIn the process of horizontal well construction, the working environment in the well is very complicated. It is difficult to determine the actual deformation and force of the coiled tubing in the wellbore from the load change at the wellhead along.

Coiling instabilities of multilamellar tubes [PDF]
Physical Review E, 2002 Myelin figures are densely packed stacks of coaxial cylindrical bilayers that are unstable to the formation of coils or double helices. These myelin figures appear to have no intrinsic chirality. We show that such cylindrical membrane stacks can develop an instability when they acquire a spontaneous curvature or when the equilibrium distance between ...

Buckling load of bending coiled tubing under an injector
Advances in Mechanical Engineering, 2018 When coiled tubing is applied in high oil–gas wells, buckling load of a coiled tubing under the injector is the key for functionality. The coiled tubing is curved, but it is simplified to straight tubing for buckling load solved in the past.
