Abstract
A method for evaluating a wellbore treatment includes inducing an acoustic wave in the wellbore prior to treatment. Acoustic energy propagating as pressure waves in the wellbore is detected. A formation in fluid communication with the wellbore is treated. The inducing an acoustic wave and detecting acoustic energy are repeated. A characteristic of the treatment is determined based on differences between the detected acoustic energy prior to the treating and at the end of the treating. In some embodiments, the observed differences are then also compared to differences observed in prior treatment stages to assess benefit of changes to treatment design. In some embodiments, the treatment design parameters are continuously iterated, adjusted, and improved to maximize the contribution to production of all subsequent stages in same or any other well.
