The technique is performed with the, injection, of, fracture fluid,, a high-pressure fluid containing water in approximately 95%, additives (0.5%) and proppant (4.5%). When the, fracture fluid, is injected, the fractures that had been generated and propagated by implosion into the reservoir expand as the proppants fill and maintain them open when the pressure is finally relieved 8 .
