    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.

    Abstract: A casing annulus remediation system for overcoming problems associated with lowering a flexible hose (51) into an annulus (21) between strings (13, 15, 17, 19) of casing in a petroleum well by pressurizing the hose (51) so that the hose is rigid and may be forced down the annulus. A nozzle (65) is affixed to the lower end of the hose. The hose may be inserted several hundred feet into the well. Therefore, the hose (51) is pressurized to maintain rigidity to keep the hose from winding about the well during deployment. To keep the hose rigid, internal pressure is maintained in the hose (51). The nozzle (65) is provided with a burst disk (69) that holds the pressure. Once the hose is lowered to a desired depth, an operator may increase the pressure sufficiently in the hose to break the disk (69), thereby allowing heavy liquid to flow out.
