A method of oil/gas well stimulation. Firstly, positioning a venturi-style pumping apparatus (12) in a wellbore (14) within a selected production zone (16) of an oil/gas producing formation (18). The pumping apparatus (12) is connected to a first conduit (21) and a second conduit (25). Secondly, activating the pumping apparatus (12) to induce a flushing of fluids and contaminants from the oil/gas producing formation (18) into the wellbore (14). Thirdly, pumping power fluid that powers the pumping apparatus (12) via the first conduit (21) and directing a portion of the power fluid through at least one fluidizing nozzle (15) to sufficiently fluidize contaminants to enable the contaminants to be removed from the wellbore (14) along with pumped fluids by the pumping apparatus (12) via the second conduit (25).
