Claim 0:
1. A method for use in a well, comprising:
coupling a pump and a one-way valve with a pressure chamber;
conveying the pump, the one-way valve, and the pressure chamber downhole into a borehole;
operating the pump to decrease a pressure level in the pressure chamber by drawing fluid out of the pressure chamber through the one-way valve while a release mechanism coupled with the pressure chamber remains closed, thereby creating a pressure differential between an interior of the pressure chamber and an exterior of the pressure chamber;
trapping the decreased pressure level in the pressure chamber using the one-way valve; and
rapidly opening the release mechanism coupled with the pressure chamber to create a pressure wave in the borehole via fluid flow between the borehole and the pressure chamber resulting from a rapid reduction of the pressure differential.
