25 Claims

1. A method comprising:

generating pressure waves that combine to create a standing wave at a specific location within a wellbore using surface pumping/pulse generating equipment;

monitoring a response of the standing wave by making measurements along the length of the wellbore using a fiber optic sensing system;

determining a difference between the specific location and a desired location of the standing wave within the wellbore based on the measurements; and

adjusting one or more properties of one or more of the pressure waves based on the difference between the specific and desired locations to move the standing wave to the desired location.
