Abstract
A method for displacing a tubular string in a wellbore can include axially vibrating the tubular string at a surface location, and reducing friction between the tubular string and the wellbore due to the axially vibrating. The axial vibration may be imparted by operation of an injector assembly. The axial vibration may be imparted by operation of a vibration tool connected between the injector assembly and a wellhead or a support structure that suspends the injector assembly. The axial vibration may be imparted by varying a flow rate of fluid into the tubular string.
Claims15
A system for use with a subterranean well, the system comprising:
- a tubular string deployed in a wellbore of the well;
- and
- an outlet of a first pump hydraulically connected to respective inlets of first and second parallel flow paths at a surface location, in which respective outlets of the first and second parallel flow paths are hydraulically connected to each other and to an inlet of the tubular string at the surface location, and in which a flow rate of fluid pumped via the second flow path is periodically varied upstream of the hydraulic connection of the respective outlets to thereby produce axial vibration of the tubular string.
