Abstract
A mathematical model is built describing the evolution of a pulse signal in a well at a longitudinal or a transverse fracture in the bottomhole section. It is assumed that the signal is sent from the wellhead with a wavelength exceeding the well diameter and the length of the open section of the well. The behavior of the echo of the pulse signal returning to the wellhead makes it possible to assess the quality of hydraulic fracturing. The results of numerical calculations for a bell-shaped pulse are presented. It is shown that in diagnosing fractures, water is preferable to oil as a fluid in which the signal propagates.
