  • Publication number: 20200003923
    Abstract: The harmonic wave, which is oscillation of a physical value along one direction of propagation in a homogeneous medium, is recorded by means of sensors along the direction of propagation of the oscillation at least at five points equally spaced from each other. The output signals of the sensors are converted into the corresponding complex spectral amplitudes corresponding to the frequency decomposition of the output signals. A model of harmonic wave propagation in a homogeneous medium is created, in which for any oscillation frequency the wave is represented as descending and ascending exponentially decaying harmonic waves propagating in opposite directions. The absolute values of the complex spectral amplitudes of the output signals of the sensors at each frequency are used as input data for equations comparing the absolute values of the complex amplitudes with the created model of wave propagation.

  • Publication number: 20140060822
    Abstract: An acoustic signal is recorded at least once, the signal being a response of a wellbore-reservoir system onto acoustic impulses of pressure. A source of the pressure impulses is an electric submersible pump located inside the wellbore. The acoustic signal is recorded at least once by at least one sensor placed in a bottomhole chamber of the wellbore, the sensor measuring at least one physical parameter of the wellbore-reservoir system, which characterizes a process of propagation of the acoustic signal in the wellbore. A mathematical model of propagation of acoustic signals in the bottomhole chamber is created and data obtained by means of modeling are compared with data obtained by means of registering of the acoustic signals.

  • Publication number: 20110276318
    Abstract: The method relates to the field of hydraulic fracturing of subsurface formations. A mathematical simulation model of a pressure pulse propagation inside a wellbore and inside a fracture is created. Pressure pulses are sent to the wellbore, and the response of the well to the pressure pulses is registered. Then, a bottom-hole pressure corresponding to each pulse is determined. An average fracture width is derived by using the mathematical simulation model of pressure pulse propagation inside the wellbore and inside the fracture, and a ratio between the simulated average fracture width and the determined bottom-hole pressure is determined. The said ratio is extrapolated to a zero-width point, and the closure pressure is determined as the bottom-hole pressure corresponding to the zero width.

  • Publication number: 20100039893
    Abstract: The invention relates to oil-gas engineering, in particular to maintaining wells in the oil-gas industry and, more specifically the hydraulic fracturing seismic monitoring. A first method is carried out when a pulse amplitude is sufficient for opening a strike-slip fractures around a crack, wherein said crack is detectable with the aid of traditional means for passively recording seismic waves produced by acoustical events related to the opening of strike-slip fractures and by interpreting the position of the thus obtained events in the form of the events adjacent to the crack.
