    Advanced well stimulation method applying a propellant based technology
    (2008) Krilov, Zoran; Kavedžija, Boris; Bukovac, Tomislav
    The world oil industry practice, during over the century of its history developed widely known conventional methods of well stimulation. Recently, an advanced well stimulation method, based on implementation of high energy (HE) materials (special explosives, propellants or rocket fuels), has shown to be competitive. The basic principles of propellant based well stimulation technology, employing propulsive thermo-chemical reaction for generation the multidirectional fractures inside reservoir rocks around the wellbore and laboratory investigation of original permeability modification on core samples due to propellant treatment are explained. Also, the well treatment procedure, using high energy gas fracturing tool, applied at two onshore oil wells in Croatia is described along with post stimulation well production results.
