Abstract
A system for use with a subterranean well can include a fluid oscillator which discharges pulsating fluid from a tubular string in a direction at least partially toward an end of the tubular string proximate a surface of the earth. A method can include discharging a fluid from the tubular string, thereby applying a reaction force to the tubular string, which reaction force biases the tubular string at least partially into the well. Another method can include discharging a pulsating fluid from a fluid oscillator in a direction at least partially toward an end of the tubular string, and drilling into an earth formation with a drill bit connected at an opposite end of the tubular string in the well.

A system for use with a subterranean well, the system comprising:
- a tubular string including first and second ports;
- and
- a fluid oscillator, wherein fluid is discharged from the tubular string alternately via the first and second ports in a first direction at least partially toward a first end of the tubular string proximate a surface of the earth, and wherein discharge of the fluid from the tubular string produces a vibratory reaction force applied to the tubular string in a second direction opposite to the first direction.
A system for use with a subterranean well, the system comprising:
- a tubular string including first and second ports;
- and
- a fluid oscillator, wherein fluid is discharged from the tubular string alternately via the first and second ports in a direction at least partially toward an end of the tubular string proximate a surface of the earth, and wherein discharge of the fluid from the tubular string applies a reaction force to the tubular string, which reaction force at least partially biases the tubular string into the well.
A method for use with a subterranean well, the method comprising:
- alternately discharging a fluid from a tubular string via first and second ports, wherein each fluid discharge applies a reaction force to the tubular string, which reaction force biases the tubular string at least partially into the well.
