Abstract

A system for oscillating compressible working fluid in a wellbore defined in a subterranean formation includes a fluid supply and a fluid oscillator device. The fluid supply communicates compressible working fluid into a conduit disposed within the wellbore. The fluid oscillator device is configured to reside in the wellbore. The fluid oscillator device includes an interior surface that defines an interior volume of the fluid oscillator device, an inlet into the interior volume, and an outlet from the interior volume. The interior surface is static during operation to receive the compressible working fluid into the interior volume through the inlet and to vary over time a flow rate of the compressible working fluid from the interior volume through the outlet.
