Abstract: A sonic oil recovery apparatus for use in a well having a casing therein, has an injector tubing adapted to extend within an interior of the casing and a resonator tube affixed to or within the injector tubing. The resonator tube having an interior flow pathway so as to allow a fluid to flow therethrough from the injector tubing. The resonator tube is suitable for transmitting an acoustic signal of greater than 30 Hz therefrom. The resonator tube has at least two orifice plates formed therein. The orifice plates include an upper orifice plate and a lower orifice plate. The orifice of the upper orifice plate has a diameter greater than a diameter of the lower orifice plate.

Abstract: A sonic oil recovery apparatus for use in a well has an injector tubing extending interior of the casing of the well, and a resonator tube affixed to or within the injector tubing. The resonator tube has an interior flow pathway so as to allow a fluid to flow therethrough from the injector tubing. The resonator tube is suitable for transmitting an acoustic signal approximately equal to the resonate frequency of a formation in the well. The resonator tube can have a plurality of orifices plates formed therein such that the fluid flowing through the resonator tube generates the acoustic signal. The resonator tube can alternatively be a solid state acoustic resonator therein.

Abstract: To increase oil recovery from an oil reservoir, an acoustic transmitter is disposed in a source well and an acoustic receiver is disposed in a producing well. A portion of the oil reservoir is disposed between the source well and the producing well. An acoustic signal is transmitted from the acoustic transmitter at frequencies of 30 Hz and greater. The transmitted acoustic signal is received by the acoustic receiver and a resonant frequency of the portion of the oil reservoir is determined based on attenuation of the transmitted signal. The acoustic signal is transmitted from the acoustic transmitter at the determined resonant frequency to reduce a boundary layer effect between oil in the oil reservoir and a surface of a substrate in the oil reservoir and between the oil and a brine interface in the oil reservoir.
