Abstract
An injection pumping system is used to generate pressure pulses in a wellbore to create pressure spikes for stimulation treatment of the wellbore. An initial pressure pulse is generated with a known travel time from the surface to a termination point and back to a specified location within the wellbore. A subsequent pressure pulse with a known travel time from the surface to the specified location can be generated to collide with the initial pressure pulse at the specified location. Knowing the speed of sound throughout the wellbore allows for an accurate calculation of the required travel times for each of the pressure pulses. Multiple sections of the wellbore can be treated preferentially and independently without requiring multiple runs of a perforating tool as the pressure pulses can be manipulated to collide at different locations throughout the wellbore based on the known travel times.
