Abstract
AbstractPrevious work has shown that large force waves traveling through the coiled tubing (CT) correlated with extended reach tool (ERT) operations can generate axial vibration harmonics in the CT that may lead to CT failures. This paper documents continued work which has shown that the surface equipment also has natural frequencies of vibration. When these natural frequencies are multiples of the ERT frequency, the ERT stimulates the surface equipment vibration modes.
