ABSTRACT:
A method and apparatus for stimulating fluid production in a producing well wherein a well stimulating tool comprising a sealed tool housing with an acoustic transducer in the housing. The tool is run into a producing well on an electric wireline and placed at a depth opposite perforations in a producing zone. The sealed housing of the tool contains a liquid to couple and enable pulses of acoustic energy from the acoustic transducer to be transmitted through the housing into well formation fluids surrounding the housing to reduce the viscosity of the formation fluids by agitation and thereby enhance fluid flow from the formation into the producing well.
